AMFT, ASW and APCC Billing: Which CA Payers Pay?

Last reviewed: October 8, 2026.

Several major payers will reimburse a California group for sessions by a registered Associate Marriage and Family Therapist (AMFT), Associate Clinical Social Worker (ASW), or Associate Professional Clinical Counselor (APCC). The associate is never the billing provider. The group bills under its Type 2 NPI, and in most cases the licensed supervisor is listed as the rendering provider.

Short answer: Optum (UnitedHealthcare) and Cigna/Evernorth publish rules that cover supervised associate services in California. Aetna allows it for in-network groups that meet its conditions. Medi-Cal’s fee-for-service manual allows it under a supervising clinician. We found no published associate rule for Blue Shield of California, Health Net, or Carelon-administered plans, so confirm those in writing before you bill.

What California requires before any payer question

The Board of Behavioral Sciences (BBS) sets who can do the work. Payers decide separately whether they will pay for it. The BBS rules that shape a group’s billing setup are the same for all three associate types (see the AMFT, ASW, and APCC FAQs):

• No independent practice. An associate cannot open their own practice and cannot be paid directly by clients. Every claim goes out under the employer.

• W-2 or volunteer, not 1099. Associates must be paid W-2 employees or volunteers. A group that wants to bill for associate sessions should hire them as employees.

• Private practice limits. An associate may work in a private practice or professional corporation only under their first registration number and only for the first six years after it is issued. Registrations renew every year.

• The supervisor’s tie to the practice. In a private practice, the supervisor must be an owner, or be employed or contracted by the practice, and either see clients for the practice or have a written contract that gives the same access to the associate’s records.

California’s mental health parity statute, Health and Safety Code § 1374.72, counts AMFTs, ASWs, and APCCs working under BBS rules as “health care providers.” Optum cites that section as the reason it pays for supervised services in California. The section applies to plans licensed by the Department of Managed Health Care. It expressly excludes Medi-Cal managed care contracts. It does not tell you how any particular payer wants the claim built.

Payer by payer

Optum / UnitedHealthcare: yes, with a specific claim format

Optum’s supervised-services reimbursement policy names California as one of five states where it reimburses services by practitioners working toward licensure. In-network and out-of-network providers can both bill it in California. The policy also covers plans administered by OptumHealth Behavioral Solutions of California. It does not cover Medicare Advantage or evaluation and management codes. Medicaid plans follow the state’s Medicaid rules.

The Optum billing guide lays out the claim. Add modifier U5 to every supervised line. Put the DQ qualifier and the supervisor’s name and credentials in box 17, and the supervisor’s NPI in 17b. The supervisor’s NPI also goes in box 24J. The group is the billing provider in box 33. All lines on one claim must have the same supervisor. More detail is in our UHC supervised billing guide.

Aetna: yes, for in-network groups that meet its conditions

Aetna’s Fall 2024 provider bulletin allows supervisory billing for license-eligible clinicians who have finished the education for their license, are completing their hours, and get regular supervision. AMFTs, ASWs, and APCCs registered with the BBS generally fit that description. The supervisor must be independently licensed, credentialed and contracted with Aetna, and employed by the same group. Virtual supervision is allowed, and the supervisor does not have to work at the same location. List the supervisor as rendering. It applies only in network. See our Aetna supervised billing guide.

Cigna / Evernorth: yes, where state rules allow it

The Evernorth Behavioral Health administrative guidelines (page 46) allow providers to bill for supervisees’ services as permitted by state licensing rules. The fully credentialed provider is listed as rendering. Because California’s BBS rules permit supervised associate practice, this is the policy that applies. Confirm the member’s plan is administered by Evernorth. See our Cigna supervised billing guide.

Blue Shield of California: no published rule found

The Blue Shield provider manual we reviewed covers supervising physicians for nurse practitioners and physician assistants. It does not address registered associates. That does not mean the answer is no. Ask Blue Shield’s behavioral health network team in writing whether it pays for AMFT, ASW, or APCC sessions billed by your group, and in what claim format, before you schedule associates with Blue Shield members.

Carelon-administered plans: confirm in writing

The Carelon provider handbook (April 2026) says participating providers should not bill in their own name for services provided by an intern or another clinician. The same handbook also mentions a Supervised Clinician Group Roster form. Which rule applies depends on the plan and contract. In California, Carelon administers behavioral health for specific plans, such as Sutter Health Plan. In our work, Carelon and Anthem Blue Cross are separate enrollment tracks in California, so a Carelon agreement does not cover Anthem members. Get Carelon’s answer for your exact plan in writing.

Health Net: no published rule found

Health Net has run its own behavioral health network since January 1, 2024, when it replaced MHN. We did not find a published Health Net policy on associate services. Ask the behavioral health network team in writing, and name the product (commercial, Covered California, or Medi-Cal), because the answer can differ by line of business.

Medi-Cal and Medi-Cal plans such as Central California Alliance for Health

Medi-Cal’s non-specialty mental health billing section (page updated September 2026) says AMFTs, APCCs, ASWs, and psychological associates may render services under a supervising clinician. The claim lists the associate’s name in box 19 or on an attachment, with the supervising clinician’s NPI as the billing provider. Associates do not enroll in Medi-Cal as licensed clinicians, so the supervisor must be enrolled through PAVE. Every Medi-Cal managed care network provider must be enrolled with DHCS (APL 22-013). Our Medi-Cal group enrollment guide covers the group setup.

Medi-Cal managed care plans set their own claim rules, and some route mental health through an administrator. Central California Alliance for Health has pointed members to Carelon for mild-to-moderate mental health care, while its May 2025 provider training also has members calling the Alliance or contracted providers directly. Confirm who holds the behavioral health contract for your counties, whether they accept associate services, and the claim format they want.

Medicare: generally no

Medicare does not pay for a pre-licensed therapist’s psychotherapy billed under a supervisor the way commercial plans do. Our Medicare incident-to guide explains why and what to do instead.

What to check with each payer

1. The exact product. Commercial, Covered California, Medi-Cal, and Medicare Advantage can follow different rules even under one brand. A plan name on the card is not always the company that administers behavioral health.

2. The supervisor’s participation under your group. The supervising LMFT, LCSW, LPCC, or psychologist must be credentialed with that payer under your group’s tax ID and Type 2 NPI, not just somewhere in the network.

3. Whether the payer rosters associates. Some payers want supervisees listed on the group roster. Others do not roster them at all. Get each associate a Type 1 NPI anyway. Some rosters ask for it, and they will need it once licensed.

4. The claim format. Supervisor in box 24J, associate named in box 19, DQ supervisor in box 17, a modifier: each payer wants a specific combination. Wrong formatting can deny or reprocess claims at an out-of-network rate.

5. Documentation. Keep the BBS registration, supervision agreement, and supervision logs on file. Make sure the billed supervisor is the associate’s real supervisor (see who you can bill under).

When to get it in writing

Get a written answer (an email, portal message, or contract amendment) before associates see a payer’s members whenever:

• the payer has no published policy that covers associates;

• the only “yes” came from a phone representative (keep the call reference number, but follow up in writing);

• the plan is administered by a different company than the one on the card;

• you are relying on a contract term rather than a published policy.

Save the answer with the effective date and product it covers. A paid claim is not proof the arrangement is allowed; payers can recoup payments later.

Setup order for a new California group

1. Form the entity California allows for your license (usually a professional corporation) and get its Type 2 NPI. See NPI Type 1 vs. Type 2.

2. Credential each supervising clinician with each payer under the group. Their approval is the bottleneck, because no associate claims go out until the supervisor is in network there.

3. Hire associates as W-2 employees, confirm their BBS registration, and sign the supervision agreement.

4. Confirm each payer’s rule and claim format, in writing where needed, and add associates to rosters where a payer requires it.

5. Set up the EHR per clinician and per payer so claims come out in the format each payer approved.

Bomi credentials California groups and bills supervised associate sessions payer by payer, after we confirm each payer’s rule and the supervisor’s participation. Billing is 4% of net collections, and credentialing is $50 per payer per clinician, with the first four free with Bomi Billing. See pricing or contact us.

Frequently Asked Questions

Can an AMFT, ASW, or APCC get their own insurance contract in California?

Not as an independent provider. BBS rules bar associates from independent practice and from being paid directly by clients, so their sessions are billed by the employing group, usually with the licensed supervisor as rendering provider where the payer allows it.

Does UnitedHealthcare pay for associates in California?

Yes. Optum’s commercial supervised-services policy covers California, in and out of network. Claims need modifier U5, the DQ qualifier with the supervisor’s name and credentials in box 17, and the supervisor’s NPI. Medicare Advantage is excluded.

Can my associate be a 1099 contractor?

No. The BBS says associates must be paid W-2 employees or volunteers, and they may not bill clients directly.

Does Medi-Cal pay for associate services?

Medi-Cal’s non-specialty mental health billing rules allow AMFTs, ASWs, and APCCs to render services under a supervising clinician, with the associate named on the claim and the supervisor’s NPI as billing provider. Medi-Cal managed care plans set their own claim rules, so confirm with the plan.

What if a payer has no written policy on associates?

Ask its behavioral health network team in writing, naming the product, your group, and the supervisor, and keep the answer with its effective date. A phone yes or a paid claim is not reliable proof.
