State Medicaid won't pay 90837: 90834, an H-code, or absorb it
Summary
When a state Medicaid program will not pay CPT 90837, the answer is almost never a substitute code: which psychotherapy codes are payable is set in that state's own plan and fee schedule. The first move is to confirm 90837 is genuinely off the schedule rather than denied for authorization, provider type or the wrong schedule. If it truly is absent, the lawful options are a shorter session billed at its own code, a service the schedule does price, or absorbing the time.

Is 90837 off your fee schedule, or just denied?
Find out which of the two it is before you change a code, because the two fixes have nothing in common. A code that is absent from the fee schedule your enrollment type bills against cannot be paid on any claim you write. A code that is on the schedule but denied is a claim problem: authorization, provider type, place of service, or a modifier the state's manual requires. Both lookups start in the same document.
There is no national list of payable psychotherapy codes to appeal to. Federal rules put the question at the state level: a state Medicaid plan must describe the policy and the methods to be used in setting payment rates for each type of service 1Ref 1Centers for Medicare & Medicaid Services, Department of Health and Human Services (2026).42 CFR 447.201 — State plan requirements.The state-level frame: each state Medicaid plan describes the policy and the methods used to set payment rates for each type of service, so the payable psychotherapy codes and their rates are a state decision rather than a national one.. The codes on the schedule, and the dollars beside them, are that state's decision, which is why the same question has a different answer in the next state over.
So the artifact you need is your own state Medicaid agency's fee schedule for the provider type you enrolled as, plus the provider manual that governs it. South Dakota is a useful example of what you may find there, because its Independent Mental Health Practitioners manual, marked updated June 2026, lists all three individual codes as covered: 90832, 90834, 90837, described as 30, 45 and 60 minutes 2Ref 2South Dakota Department of Social Services, Division of Medical Services (2026).South Dakota Medicaid Billing and Policy Manual: Independent Mental Health Practitioners.South Dakota as the single named example: this state's independent practitioner manual, marked updated June 2026, lists 90832, 90834 and 90837 as covered, and states the lesser-of reimbursement rule and the rule that a claim may contain only codes listed on that fee schedule.. One state's manual is one state's manual, and the point of naming it is that the premise in the question is not true everywhere.
Watch for the second trap in the same search. A state often publishes several behavioral health schedules, one per program or provider type, and a rate you found on the wrong one is a rate you cannot bill.
What 90834 can carry, and what it cannot
90834 can carry a session that actually ran inside its time band, and nothing longer. A Medicare contractor's coding article shows where the bands sit: 16 to 37 minutes for 90832, 38 to 52 minutes for 90834, and 53 or more minutes for 90837, with psychotherapy of less than 16 minutes not reported at all 3Ref 3First Coast Service Options, Inc. (A and B MAC, Jurisdiction N), for the Centers for Medicare & Medicaid Services (2025).Billing and Coding: Psychiatric Diagnostic Evaluation and Psychotherapy Services (A57520).The psychotherapy time bands separating 90832, 90834 and 90837, the instruction not to report psychotherapy under 16 minutes, and the requirement that start and stop times or total times be documented. Cited as a Medicare contractor's jurisdictional article, never as Medicaid policy.. That article binds one Medicare jurisdiction in its 2025 revision, and it is not any state's Medicaid rule.
The same article also puts the time in the note and not only in the code: start and stop times or total times must be documented for 90832, 90834 and 90837 3Ref 3First Coast Service Options, Inc. (A and B MAC, Jurisdiction N), for the Centers for Medicare & Medicaid Services (2025).Billing and Coding: Psychiatric Diagnostic Evaluation and Psychotherapy Services (A57520).The psychotherapy time bands separating 90832, 90834 and 90837, the instruction not to report psychotherapy under 16 minutes, and the requirement that start and stop times or total times be documented. Cited as a Medicare contractor's jurisdictional article, never as Medicaid policy.. That is where downcoding from 90837 to 90834 stops being a billing workaround. Your note documents an hour and your claim states 45 minutes, and the two are now describing different sessions in the same chart.
But the version of that move that survives a chart audit is available, and it costs you the same fifteen minutes. Schedule the session at the length the schedule prices, run it there, and bill the code that matches it.
Two more mechanics decide the arithmetic for a solo practice, and South Dakota's manual states both plainly: payment is the lesser of the provider's usual and customary charge or the fee schedule amount, and the claim may contain only those procedure codes listed on the fee schedule 2Ref 2South Dakota Department of Social Services, Division of Medical Services (2026).South Dakota Medicaid Billing and Policy Manual: Independent Mental Health Practitioners.South Dakota as the single named example: this state's independent practitioner manual, marked updated June 2026, lists 90832, 90834 and 90837 as covered, and states the lesser-of reimbursement rule and the rule that a claim may contain only codes listed on that fee schedule.. Raising your posted fee does not raise the payment, and a code the schedule omits does not become billable because the session earned it.
The H-code branch is about your enrollment, not your preference
Whether you can bill an H-code is settled by how you enrolled. An H-code is a different service from 90837, usually priced on a different schedule, and the length of the visit has no bearing on your access to it. Reading a rate off a schedule your provider type does not bill against is the most expensive version of this search, because the claim denies after the work is done.
South Dakota shows the shape. Its community mental health centers schedule, carrying FY27 rates effective June 1, 2026, prices individual therapy under CPT 90832 in 15-minute units, and prices child and youth individual therapy under HCPCS H2021, also in 15-minute units, at $44.85 for FY27 4Ref 4South Dakota Department of Social Services, Division of Behavioral Health (2026).Contract and Medicaid Mental Health Service Codes FY27 Effective June 1, 2026.The H-code shape in one state: South Dakota's community mental health centers schedule, FY27 rates effective June 1, 2026, prices individual therapy under CPT 90832 in 15-minute units and child and youth individual therapy under HCPCS H2021 in 15-minute units at $44.85, on a schedule separate from the independent practitioner one.. That schedule is a separate document from the independent practitioner manual above, and the state fiscal year is the unit of change: these rates are replaced on their own annual cadence.
The part that generalizes is the accounting. Where a state prices a service in 15-minute units, an hour of work is billed as four units of that service rather than as one code with a time band, and the length of the session stops being a coverage question. Whether your enrollment reaches that schedule at all is the question to answer first, in writing, with your state agency's provider enrollment staff.
If the limit is the plan's and not the state's
Then you have a sentence of federal regulation to quote in the appeal. A Medicaid managed care organization's specification of medically necessary services must be no more restrictive than the one used in the state Medicaid program, including quantitative and non-quantitative treatment limits 5Ref 5Centers for Medicare & Medicaid Services, Department of Health and Human Services (2026).42 CFR 438.210 — Coverage and authorization of services.The managed-care branch: an MCO, PIHP or PAHP's specification of medically necessary services must be no more restrictive than the one used in the state Medicaid program, including quantitative and non-quantitative treatment limits.. It does not require any plan to cover 90837. It constrains the plan against the state, which is a narrower and more usable point.
So the comparison worth building is state medicaid vs its mcos, on paper, before you write anything. Pull the state plan's fee schedule and confirm 90837 sits on it for your provider type. Pull the plan's own provider manual and find the sentence that limits it. An appeal that puts the two side by side is making an argument the regulation recognizes.
Calendar the appeal deadline the day the denial arrives, and take it from the plan's own manual rather than from memory, because those windows are contract terms and they vary between plans in the same state.
The difference cannot be moved to the patient
Absorbing the gap is the default, and one federal condition of participation is the reason. A state plan must limit participation in the Medicaid program to providers who accept, as payment in full, the amounts paid by the agency, plus any cost sharing the plan requires of the patient 6Ref 6Centers for Medicare & Medicaid Services (2013).§ 447.15 Acceptance of State payment as payment in full..Why the gap cannot be invoiced to the patient: a state plan must limit participation to providers who accept the agency's payment, plus any required cost sharing, as payment in full for a covered service.. The distance between a 45-minute rate and an hour of your time is therefore not a balance you can invoice while you are enrolled and billing for that service.
The one door that exists runs through noncovered services, and states word it differently. South Dakota's billing manual, marked updated June 2024, is a concrete version: providers may not seek additional compensation from family, friends, political subdivisions, or the eligible individual unless the services provided were a noncovered medical service, and the patient must be told in advance that the service is not covered and that they will be responsible 7Ref 7South Dakota Department of Social Services, Division of Medical Services (2024).South Dakota Medicaid Billing and Policy Manual: Billing A Recipient.The concrete shape of the noncovered-service exception in one state, including the advance-notice condition attached to it, presented as South Dakota's wording against the federal floor rather than as a national rule..
Whether a code your state does not price counts as noncovered for that purpose is a state question, and the fee schedule alone does not answer it. The manual does, or the agency's provider relations staff does in writing. Get that answer before the visit rather than after, because the advance-notice condition is the part that cannot be repaired retroactively.
The lookups, and the decision that stays yours
Three documents settle almost every version of this question, and you can pull all three in an afternoon: the fee schedule for the provider type you enrolled as, the provider manual that governs that schedule, and, when the patient is in managed care, the plan's own manual. Read them in that order. What you find puts you in one of four branches, and the branch decides the move.
| What you found | Where to confirm it | What it leaves you |
|---|---|---|
| 90837 is not on the schedule for your provider type | the schedule, plus the manual that governs it | a session run at a band the schedule prices, or unpaid time |
| 90837 is on the schedule and the claim denied | the denial reason, plus the manual's authorization and modifier rules | a corrected claim rather than a different code |
| The limit is the plan's and not the state's | the plan manual read against the state schedule | an appeal on the no-more-restrictive rule |
| The service is priced in 15-minute units or on another schedule | the schedule your enrollment reaches | whatever that schedule pays, if you are enrolled for it |
If the number that moved is tied to your license type instead of the code, state medicaid's np payment percentage is the same lookup on the same page, and it is worth reading at the same time.
What none of this settles is whether the schedule still supports the sessions you want to run. The schedule tells you only what it pays. That question is about your panel and your own numbers, and it belongs to you and whoever helps you read your books.
