Getting on insurance panels in California, and the arithmetic nobody runs first

The question every caller asks first

Somebody rings. Before they tell you anything about why they are ringing, they ask whether you take their insurance. You say no, and a good share of those calls end there.

That is the whole decision, and it is not an ideological one. It is a decision about which hours in your week are empty. A panel does not make your full hours pay better — it makes your empty hours pay something. Everything else follows from that.

What is missing from almost everything written on this is the sequence and the numbers. This page gives you both: the steps in the order a payer actually needs them, the clock California law imposes on plans and where that clock does not apply, which panels were open to a California LMFT, LCSW or LPCC as of August 2026, whether Medicare is worth enrolling in now that it is open to you, and what a panel caseload is worth after you price the unbilled work it brings with it.

One thing to settle before you start: this page is about what panels pay you and cost you in time. What they pay per session, by payer and by region, is on the reimbursement page and the rate gap page, and it is a thinner evidence base than anyone admits — payers treat contracted rates as confidential and most will not quote you a number until you are already credentialed.

The order of operations, and what each step needs

Seven steps. They do not run in parallel, and skipping one does not save time — it just moves the delay later, where it costs more.

1. An NPI, Entity Type 1. The National Provider Identifier is “the 10-digit standard unique health identifier for health care providers”, and Type 1 is the individual one: “For individual health care providers, such as physicians, nurse practitioners and sole proprietors. Individuals are only eligible for one NPI.”^[1] You apply at NPPES. It follows you for the rest of your career, through every name change and every move.

Type 2 is a different animal. Type 2 is for organizations. You need one the moment you stop being the billing entity yourself — that is, when you incorporate and claims go out under the corporation’s tax ID rather than your Social Security number. In California a licensed therapist cannot form an LLC to deliver clinical services,^[35] so the entity in question is a professional corporation; whether that is worth doing at all is a separate question, worked through on the sole proprietor or professional corporation page. If you are a sole proprietor billing under your own name, you do not need a Type 2 and should not get one.

2. A CAQH profile. This is the shared credentialing database nearly every commercial payer reads instead of asking you the same forty questions each. CAQH rebranded as DataSpring on 7 June 2026; the provider login is still at proview.caqh.org and nothing about your profile changed.^[3]

The profile is not a one-off. CAQH’s instruction to providers is to attest “every 120 days”,^[2] and payers restate it as a condition of participation — Evernorth tells applicants to “Attest that all your information is correct every 120 days”.^[4] Three times a year, forever. Let it lapse and your file goes stale in every payer’s queue at once, which is the single most common self-inflicted delay in this whole process.

Evernorth also publishes the most specific list of what has to be in the profile, and it is a fair guide to what every payer wants:^[4]

• A current state license for every location you will work in, with an expiry date at least 60 days away.
• Professional liability insurance, again with at least 60 days to run — Evernorth’s own minimum for a non-prescribing clinician is $1 million per occurrence and $1 million aggregate.
• A W-9 for the taxpayer identification number you are applying under.
• Five years of consecutive work history with no unexplained gap longer than six months. Education counts as history. This is the item that stops applications, because most people have not written it down anywhere.
• Authorization for that specific payer to read your profile. A complete profile the payer cannot see is the same as no profile.

3. The application itself. Some payers work straight from CAQH; others want their own form first. Aetna asks behavioral health clinicians to complete a Behavioral Health Provider Application Request form, promises an acknowledgment “within 7-10 business days” and a CAQH registration package within 10–14, and warns that “completing the request form does not guarantee participation in our network”.^[36] Health Net has a separate Behavioral Health Network Participation Request form covering “Psychiatrists, MFT, LCSW, PhDs”.^[13] Blue Shield of California takes an application packet by email or fax and requires it to be “dated no more than thirty days from submission”.^[9]

4. Primary source verification. The plan does not take your word for your license; it checks with the BBS, with your malpractice carrier, with the National Practitioner Data Bank. California’s statute calls this to “assess and verify the qualifications of a health care provider”.^[5] Nothing you do speeds this up except giving them a file with no holes in it.

5. The contract. Credentialing decides whether you are qualified. The contract decides whether they want you, on what terms, in which networks. These are two different decisions made by two different departments, and the law is explicit that they are not the same clock: “The 60-day timeline shall apply only to the credentialing process and does not include contracting completion.”^[5][6]

6. The fee schedule — which is a negotiation. This is the step most therapists do not know exists as a step. The rate is an exhibit to the contract, and it is filled in before anyone verifies anything about you. Blue Shield of California states the order plainly: “Upon submission of a completed application packet, signed contract, and rates as outlined, the credentialing process will begin.”^[9] The rate is settled first. If you sign whatever arrives, you have negotiated, and you have lost.

Ask for the fee schedule for your CPT codes in writing before you sign, and put your counter in terms of a percentage of the Medicare rate for your locality — that is the language the contracting department already thinks in, and the Medicare number is the one rate in California that is genuinely published. The next-but-one section shows you how to compute it for your own city.

Once you have signed, California gives you something: under the Health Care Providers’ Bill of Rights, a plan contract may not give the plan “Authority to change a material term of the contract, unless the change has first been negotiated and agreed to by the provider”, and any change requires at least 45 business days’ notice with a right to terminate before it takes effect.^[8] Your rate is a material term. This does not stop a plan proposing a cut; it stops the cut arriving silently.

7. The effective date. Contracts are not backdated. Blue Shield’s own wording: “Services rendered to Blue Shield members prior to this effective date will process as out-of-network.”^[9] Do not start seeing a payer’s members on the strength of a welcome email that has no date in it.

How long it actually takes, and what the law requires

California is one of the few states with a statutory clock on this, and it is specific to your profession. For provider contracts issued, amended or renewed on or after 1 January 2023, a health plan that covers mental health and substance use disorders “shall assess and verify the qualifications of a health care provider within 60 days after receiving a completed provider credentialing application”, and must acknowledge receipt within seven business days, telling you whether the application is complete.^[5] The identical rule applies to insurers regulated by the Department of Insurance rather than the DMHC.^[6]

Two catches, and they are the whole reason the 60 days rarely describes your experience. The clock starts on a completed application, and the plan decides what complete means. And it covers credentialing only — not contracting, not the fee schedule, not the effective date.

That gets wider from 2027. AB 1041, signed in October 2025, requires a determination within 90 days of a completed application, an acknowledgment within 10 business days, and provisional approval for 120 days if the plan misses the deadline — all from 1 January 2027. Mental health and substance use disorder providers keep the tighter 60-day rule. From 1 January 2028 plans must use the current CAQH credentialing form and follow CAQH processes.^[7]

A realistic range, then. Where the payer is open, your CAQH file is complete and attested, and you accept the rate offered: 60 to 120 days per payer. Where any of those three is untrue, it runs longer, and the extra time is almost never the verification — it is the queue in front of it, or the contract behind it.

What pushes it long, in rough order of how often it happens: a CAQH attestation that lapsed while you were waiting; a work-history gap you never explained; a license or liability certificate inside 60 days of expiry; a payer that reviews network need before it will even credential you, which is Aetna’s published step two;^[11] a rate you are negotiating, which is outside the statutory clock entirely; and a panel that is simply closed.

Which panels were open in August 2026

Checked against each payer’s own provider pages in the first week of August 2026. Where a payer does not publish its status, this table says so rather than guessing — a confident wrong answer here costs you a month.

The closed one is Evernorth, and the date is 1 September 2026. Its provider page says: “As of June 1, Evernorth has paused accepting applications from new individual and clinic providers seeking to join our behavioral health network.” It directs everyone else to an interest form “to be contacted when our application process reopens, or revisit this webpage after September 1, 2026”, and promises “a new and improved application and credentialing experience in September”. Facilities can still apply throughout. If you started before 1 June 2026, your application “will not be impacted and will be processed as expected”.^[4] There is one narrow exception, and it is not a side door for private practice: a clinician delivering behavioral services inside a Cigna-participating medical practice who does not take direct referrals from the community can be added to that practice’s medical contract instead. Anyone seeing community referrals, or working in their own practice, is sent to Evernorth.^[4]

Optum is the clearest yes on the list. Provider Express states it is limiting additions only to its Arizona Medicaid network, and that “Our commercial and Medicare Advantage networks remain open to all types of behavioral health providers.”^[12] That is an unusually explicit statement and worth acting on while it stands.

Blue Shield changed shape on 1 January 2026. Magellan’s own notice reads: “Effective Jan. 1, 2026, Magellan no longer manages the behavioral health services for Blue Shield of California members.”^[14] Blue Shield now credentials behavioral health directly.^[9] Any advice you read about Blue Shield rates dated 2025 or earlier is describing a payer relationship that no longer exists. One quirk of the new arrangement worth knowing before you sign: “A behavioral health practitioner may not be listed in more than ten (10) in-person service location addresses across the entire network.”^[9]

Kaiser is the one nobody can answer for you. Southern California publishes a single line — behavioral health providers “send a letter of intent to Regional Behavioral Health Department at SCAL-BH-Panel@kp.org” — alongside a general warning that submissions “are not a guarantee that you have been accepted as a contracted provider”.^[16] Northern California publishes no equivalent route for individual clinicians, and its status cannot be established from a public page. The reason to try anyway is context: in October 2023 the DMHC fined Kaiser $50 million, the largest fine it has ever levied on a health plan, for failing to give members timely behavioral health appointments, and Kaiser committed a further $150 million over five years, including improving how it refers members out of network.^[17] Kaiser has a structural reason to buy outside capacity. It has no public front door for it.

Medi-Cal has two doors and they are not interchangeable. The county Mental Health Plan covers specialty mental health for higher-acuity members and contracts mostly with organizational providers; DHCS says a provider “must be certified by the Department of Health Care Services” before it can be reimbursed.^[19] Non-specialty mental health — the mild-to-moderate outpatient work most solo practices do — runs through the Medi-Cal managed care plan, and there you must also be enrolled with the state: federal rules require the state to screen and enroll every network provider, so a contract with the plan alone is not enough.^[18] Start with PAVE, DHCS’s enrollment portal, and expect 120 days if the plan screens you and up to 180 if DHCS does.^[18]

One warning about county rates, because they look extraordinary and are not what you would be paid. DHCS publishes county specialty mental health fee schedules where the MFT/LPCC maximum for 90837 is $435.39 in Los Angeles and $548.91 in San Francisco for 2025–26.^[21] Those are program rates paid to a county Mental Health Plan’s contracted organizational providers, carrying an organization’s overhead, supervision and documentation burden. The rate a solo practice sees under Medi-Cal is the non-specialty fee schedule, and there the published maximum for an LMFT, LCSW, LPCC or psychologist is $67.16 for 90834 and $128.08 for 90791.^[20] Read that table carefully before you plan around it: the same published page lists 90837 at $38.01 in the non-physician column, less than the 45-minute code above it. That is what the manual says; it is very likely an error, and it is exactly the kind of thing to get in writing from the plan before you build a caseload on it.

Medicare, which is open to you and was not two years ago

This changed on 1 January 2024. Under section 4121 of the Consolidated Appropriations Act, 2023, “Payment for MFT and MHC services under Part B of the Medicare program will begin January 1, 2024.”^[22] Before that date an LMFT or LPCC could not bill Medicare at all. LCSWs and psychologists always could.

CMS asks for a master’s or doctoral degree that qualifies you for licensure, a current state license, and “at least 2 years or 3,000 hours of post master’s degree clinical supervised experience”.^[22] If you licensed in California you have already done exactly that — the BBS requires 3,000 hours, and if you are still counting them, the hours planner is the page you want first.

The route is short. Set up an Identity & Access Management account, which is what gets you into both NPPES and PECOS; then enroll either “electronically using the Provider Enrollment, Chain, and Ownership System (PECOS) or the paper CMS-855I enrollment application”.^[22] The separate CMS-855R reassignment form has been merged into the CMS-855I, so if you are reassigning your benefits to your own corporation it is one form now.^[25] There is no fee: “Physicians, non-physician practitioners (NPPs)… don’t pay a Medicare enrollment application fee.”^[25] Answer any request from your contractor within 30 days or the application can be rejected outright.^[25]

Now the money, which you can compute exactly — this is the one in-network rate in California that is genuinely published. MFTs and MHCs are paid “80 percent of the lesser of the actual charges for the services or 75 percent of the amount determined for the payment of a psychologist”,^[23] which Noridian, the Medicare contractor for California, states as 75 percent of the physician fee schedule amount.^[24] The fee schedule amount itself is relative value units times your locality’s geographic indices times the conversion factor. For 90837 in the Los Angeles locality in 2026:

• Work 3.78 RVU × 1.041 = 3.935
• Practice expense (non-facility) 1.20 RVU × 1.183 = 1.420
• Malpractice 0.02 RVU × 0.664 = 0.013
• Total 5.368 × $33.4009, the 2026 conversion factor for practitioners who are not qualifying APM participants, = $179.29 — the psychologist amount
• × 75% = $134.47 — what an LMFT or LPCC is allowed^[26]

Computed from the CMS 2026 relative value file and the 2026 geographic practice cost indices, then reduced by the statutory 25 percent — the same arithmetic, code by code, is laid out on the page on what insurance actually pays.^[26][23] Medicare pays 80 percent of the allowed amount and the member or their supplement owes the other 20 percent — on a Los Angeles 90837 that is $107.58 from Medicare and $26.89 you have to collect. You cannot routinely waive the 20 percent.

Is it worth doing? For most California practices, yes, for a reason that has nothing to do with the rate. Medicare is the only panel that cannot say no to you on network need. It does not close, it does not review whether your zip code has enough therapists, and its rate is the benchmark you will use to argue with every commercial payer. Enrolling costs you a form and no money.

The honest caveats. The rate sits below Bay Area private pay by a wide margin and above what several commercial panels pay. You will collect a 20 percent balance from people on fixed incomes. And if you decide you would rather see Medicare beneficiaries privately, you cannot simply not bill — you have to formally opt out, which is a two-year commitment that renews automatically.^[24] Enrolling and opting out are the two lawful options; drifting is not one of them.

The arithmetic that decides it

Here is the comparison nobody publishes, on a stated caseload: 20 sessions a week, 46 working weeks, 920 sessions a year, in Los Angeles. Expenses, tax and the entity question are identical across all three columns, so they cancel and are left out.

The in-network column uses $134.47, the 2026 Medicare allowed amount for 90837 computed above — not because Medicare is the panel you would join, but because it is the only California in-network rate that is published and checkable, and commercial behavioral health contracts are commonly written as a percentage of it. Substitute your own offer when you have one.

The 90 hours are the part everybody leaves out, and they are an estimate rather than a published figure, so here is exactly how they are built. Six payer applications at five hours each — forms, chasing, the contract read — is 30 hours. Three CAQH re-attestations a year at 40 minutes each, on the 120-day cycle CAQH requires,^[2] is 2 hours. And claims: at the 19 percent in-network denial rate KFF measured across HealthCare.gov marketplace issuers in 2024,^[31] 920 claims produce about 175 that need working, and 20 minutes each is 58 hours. That is 90 hours. Substitute your own numbers — the KFF figure covers all claim types, not therapy specifically, and the minutes are mine, not anybody’s data.

Two numbers fall out of the table. The first: 11.5 hours a week of private pay at $200 produce what 20 hours a week on a panel produce, once you have paid yourself for the panel work. If you can reliably fill 529 private-pay sessions a year, the panel is costing you money, not making it.

The second: a platform like Headway or Alma has to pay you $115.77 a session before it beats holding the contract yourself. That is the direct column’s $105,712, plus the roughly four hours of onboarding a platform still costs you, divided by 920 sessions. Neither Headway nor Alma publishes a California rate — rates are visible only after you are credentialed — so the honest thing to do is take the number they offer you and hold it against $115.77 rather than against the gross contracted rate.

Three cautions, because a table this clean always hides something. Private pay is not really zero unbilled hours — it is marketing hours, superbills and a fuller no-show rate, and those belong in your own version. The 20 in-network sessions are, by assumption, hours you could not have filled privately; if they are not, the whole comparison collapses in private pay’s favor. And the 90 hours are heaviest in year one; by year three the credentialing block is gone and only the claims work remains, which is 60 hours, $12,000, and moves the direct column up to $121.43 an hour.

The way to use this is not to accept my $200 and my 20 sessions. Put your own fee, your own filled hours and your own expenses into the practice simulator, run it twice, and compare the two net figures. If the problem is that the hours are empty rather than that the rate is low, the referral and funnel arithmetic is the cheaper fix and you should try it before you spend 90 hours on credentialing.

What goes wrong, and what to do about it

The codes, and the two errors that generate most therapy denials. 90791 is the psychiatric diagnostic evaluation. The psychotherapy codes are timed, and CPT’s rule is that “a unit of time is attained when the mid-point is passed” — so 90832 covers sessions over 15 minutes, 90834 covers 38 to 52 minutes, and 90837 requires 53 minutes or more.^[32] A 50-minute hour is a 90834. Billing 90837 for it is the most common error in this field, and because 90837 pays more, it is the one payers watch. Write the start and stop time in the note, every time. The second error is 90791: most payers reimburse one per episode of care, and a second one needs a documented reason.^[32]

Telehealth in 2026. Behavioral health telehealth to the patient’s home is allowed for Medicare in urban and rural areas alike, and audio-only is permitted: “Two-way, interactive, audio-only technology is permitted for behavioral health telehealth services.”^[33] Use place of service 10 when the patient is at home and 02 when they are somewhere else.^[33] The in-person visit requirement — one within six months before the first telehealth mental health service, and annually after — does not bite until 1 January 2028, and patients already in telehealth treatment by 31 December 2027 count as established and need only the annual visit.^[33] On modifiers, CMS’s FAQ specifies the place-of-service codes and not the modifier; modifier 93 is the CPT modifier for “Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system”,^[34] and 95 is the audio-video one. Commercial payers differ on which they require. Ask each one in writing before your first telehealth claim rather than after your first denial.

Timely filing. California sets a floor, not the number in your contract: a plan “shall not impose a deadline for the receipt of a claim that is less than 90 days for contracted providers and 180 days for non-contracted providers after the date of service”.^[28] Ninety days is short. Medicare is far more generous — “the claim must be filed no later than the close of the period ending 1 calendar year after the date of service”.^[27] Find the number in your own contract and put it somewhere you will see it, because a claim filed late is not appealable on the merits; it is simply gone.

When the payer does not pay. A plan must reimburse a complete claim “no later than 30 calendar days after receipt”, and if it does not, “interest shall accrue at a rate of 15 percent per annum” from day 31 — automatically, “without requiring the claimant to submit a request for the interest amount”. A plan that fails to include the interest owes you a further $15 or 10 percent of the accrued interest, whichever is greater.^[29] Almost no solo therapist ever claims this. It is real money on an aging receivable and it costs one sentence in a letter.

If that fails, the DMHC runs a Provider Complaint process, but read the sequence before you use it: “Before the DMHC conducts a review, the provider is required to submit the dispute to the payor’s Provider Dispute Resolution (PDR) mechanism for a minimum of 45 working days or until receipt of the payor’s written determination, whichever period is shorter.” You will need the PDR letter, the plan’s determination, the claim and the remittance advice. As of 1 July 2026 the window for a new complaint is 30 months from the last date of service, down from four years.^[30]

And when a payer takes six months to credential you. The unglamorous answer is that your leverage is the paper trail and the statute, in that order. On the day you submit, email the credentialing address a one-line note recording the date and asking for the seven-business-day completeness acknowledgment that section 1374.197 requires; that single email converts “we never received a complete application” into a dated fact.^[5] At day 60, write again and cite the section by number. Escalate to the network manager whose name is on the contract, not to the general line.

What you should not expect is a regulator to intervene. The DMHC’s published provider route is a claims-payment mechanism;^[30] it publishes no equivalent process for a credentialing delay on its own, and AB 1041’s provisional-credentialing remedy does not start until 1 January 2027.^[7] Until then the practical protection is to have applied to more than one payer at once, so that no single queue is your whole plan.

What to do on Monday

Do not panel if you are full at your private-pay fee, or you can reliably fill 11.5 hours a week at $200 or better — the table above says the panel is subsidising the payer, not you. Do not panel if you are within two years of retiring or leaving California, because you will spend year one paying the credentialing cost and year two unwinding it. Do not panel if 90 hours of unbilled administration in a year is the thing most likely to make you stop practicing; that is a real answer and it is a common one.

Do panel if your hours are genuinely empty, or you are new enough that a directory listing is your cheapest referral source, or you hold a specialism the payer directories are short of in your county, or your referrals come from medical offices — a doctor cannot easily refer to someone their patient cannot afford.

If you are going ahead, the order matters more than the speed:

• Week one, before you apply anywhere. Get the Type 1 NPI if you do not have one. Build the CAQH profile completely — five years of work history with no unexplained gaps, license and liability certificate both more than 60 days from expiry, W-9 uploaded — and attest. Put the next attestation date in your calendar three times over, at 120-day intervals.^[2]
• Then the two largest open panels in your county, which in most of California means Anthem Blue Cross and Blue Shield of California. Both are accepting; Blue Shield wants the rate settled in the same packet, so decide your number first.^[9][10]
• Then Optum, because it is the one payer stating in writing that its commercial and Medicare Advantage networks are open.^[12]
• Then Aetna and Health Net, both open, both with their own behavioral health forms rather than a CAQH-only route.^[36][13]
• Medicare whenever you like. It is not competing for a slot and it does not close. Enroll through PECOS; there is no fee.^[25]
• Evernorth after 1 September 2026, and not before — an application submitted into a paused queue is not a head start.^[4]
• Kaiser last, by letter of intent, with no expectation.^[16]
• Medi-Cal only if you mean it. PAVE enrollment first, then the managed care plan or its behavioral health delegate, and read the non-specialty fee schedule before you commit.^[18][20]

Four to six payers is a practice. Ten is a second job. Start with two, see what the claims work actually costs you over a quarter, and add the third only after you know. And whatever you sign, keep enough private-pay hours that no single contract renegotiation can move your income without your agreement — which is, in the end, the only protection the rate page can offer you.
