Billing for Innovative Mental Health Therapies: 5 Easy Steps

Billing for innovative mental health therapies means getting paid for newer treatments, such as digital treatment devices, nasal esketamine or magnetic stimulation, under codes and coverage rules that already exist. A new therapy has no billing rules of its own. It is paid only when it fits a code, the payer’s coverage policy and your documentation.

Do insurers pay for new mental health therapies?

Only when the therapy fits an existing billing code and the payer’s coverage policy for it. Medicare has created codes for some, such as digital mental health treatment devices. For other treatments, one payer may cover them while another denies them. Check the specific payer’s policy before the first session, not after the first claim.

Step 1: Find the code first

In billing for innovative mental health therapies, payers pay for codes, not for treatment names. Before you add a new service, find the CPT or HCPCS code (the procedure and supply codes used on claims), or confirm that none exists. If no code fits, ask the payer before you bill. Do not pick an unrelated code to get paid. Your compliance officer or counsel can advise if you are unsure.

These examples show how different the code paths are for billing for innovative mental health therapies. Always confirm the current policy with the payer or the Medicare contractor.

Therapy	Code path	What to confirm
Digital mental health treatment (DMHT) devices, Medicare	HCPCS G0552, G0553, G0554	The device must be cleared or authorized by the FDA and used with clinician-supervised care under a treatment plan. G0552 covers the device supply and onboarding and is contractor-priced.
Esketamine nasal spray (Spravato), Medicare	HCPCS G2082 or G2083, by dose	One Medicare contractor’s bulletin says the codes include two hours of observation, no separate drug code, and a KX modifier for enrollment in the drug’s safety program.
Repetitive transcranial magnetic stimulation (TMS)	CPT 90867, 90868, 90869	Initial session, subsequent sessions and motor threshold redetermination. Coverage, diagnosis and authorization rules vary by payer.

Step 2: Get the coverage policy in writing

Billing for innovative mental health therapies depends on each payer’s own policy, so ask each payer for its written policy on the therapy and save it with the date. Note the covered diagnoses, provider types, settings and limits. A verbal answer on a phone call will not help you in an appeal. Our guide to patient benefit verification lists the questions to ask about the plan itself.

Private payers

For billing for innovative mental health therapies, each plan sets its own rules for new treatments, and the answer can differ by plan within one insurer. Network status matters too. See how in-network and out-of-network credentialing change what a plan will pay.

Medicare and Medicaid

For Medicare, start with the CMS summary of the 2026 Physician Fee Schedule final rule. It expanded payment for G0552, G0553 and G0554 to devices for attention-deficit/hyperactivity disorder (ADHD) and says the practitioner is supplying the device as part of ongoing behavioral health treatment. The Spravato details come from a CGS Administrators bulletin revised December 21, 2023. CGS is one Medicare contractor, so check yours. Medicaid is set state by state, so use your state Medicaid manual and plan bulletins.

State rules

States differ. One example: for Medi-Cal managed care members in Los Angeles County, an Anthem Blue Cross provider notice dated June 16, 2025 says TMS codes need prior authorization and specific diagnoses. That is a California rule, not a rule for the states we serve. Never apply one state’s policy to another.

Step 3: Check authorization and telehealth rules

Prior authorization and telehealth rules decide whether a claim pays, so settle both before the first visit. For Medicare, the telehealth flexibilities run through December 31, 2027, according to CMS’s telehealth FAQ updated October 9, 2026. Behavioral health telehealth has no geographic or place restrictions, so a client can be at home. Use place of service (POS) 10 for telehealth in the client’s home and POS 02 for telehealth elsewhere.

The in-person visit requirement for mental health telehealth at home does not apply through December 31, 2027, per HHS telehealth.hhs.gov (updated February 5, 2026). Plan for it after that date. Commercial and Medicaid plans set their own telehealth rules, so verify each one.

Step 4: Document to the code

Your note has to show that the service you billed happened as the code describes, and good notes are what hold up billing for innovative mental health therapies on appeal. Record the diagnosis, the treatment plan, the start and stop times where a code is time-based, and any required observation. For a device-based service, document how it fits the plan of care. Psychiatrists should keep the E/M visit and any psychotherapy add-on documented separately. When a denial arrives, our guide to CARC and RARC codes shows what the payer is telling you.

Step 5: Explain the client’s share and reconcile it

Cost-share is a routine part of billing for innovative mental health therapies. Tell the client before the first visit what a covered session may cost them, in writing, and say it is an estimate until the claim is paid. New treatments often carry coinsurance or a copay, and that share is calculated on the allowed amount. Our post on coinsurance in therapy billing shows how to calculate it. For Medicare outpatient mental health care, Medicare.gov says the client pays 20% of the Medicare-approved amount after the Part B deductible. When the remittance arrives, read it with our guide to the electronic remittance advice and correct any difference.

What to do Monday morning

1. Name the therapy you want to offer and write down the code you think fits.
2. Call or log in to each payer and request the written coverage policy.
3. Ask about authorization, telehealth, provider type and diagnosis limits.
4. Update your intake and financial policy so clients see their estimated share first.
5. Bill one test claim for each payer and read the remittance before you expand.

The short version: billing for innovative mental health therapies

Billing for innovative mental health therapies comes down to code, coverage, authorization, documentation and a clear client estimate. Find the code, get each payer’s policy in writing, and test one claim before you scale.
