CPT 2027 for Psychiatry: What Actually Changes in January

The 2027 CPT code set is due from the AMA in early September 2026, takes effect January 1, 2027, and everything published so far leaves the core psychiatry codes alone. The diagnostic evaluations (90791, 90792), the psychotherapy family (90832-90838), and the 99202-99215 office-visit ladder appear in none of the early-release changes. What is already public: 58 new Category III codes for emerging technology, a rebuilt maternity code set, and a revision of the adaptive behavior services family. For a cash-pay psychiatric practice, January 2027 currently looks like a verify-and-move-on month rather than a re-coding project.

Status as of drafting (August 2026). This is a pre-release read built from the AMA's early-release 2027 changes and the CY2027 Medicare Physician Fee Schedule proposed rule (released July 14, 2026; comment period closes September 14, 2026). The full CPT 2027 set is expected from the AMA in early September, and the final Medicare rule around November 1. Anything labeled "proposed" below can still change. This post will be revised when both documents land; the Updated date above tells you whether that has happened yet.

What is actually changing in the 2027 CPT code set?

Three change sets are public so far, and none of them touches the codes a psychiatric practice bills every week.

The maternity restructuring and the Category III additions are confirmed by the AMA itself, both effective January 1, 2027.

For scale, a normal year churns a few hundred codes: the CPT 2026 update, announced by the AMA on September 11, 2025, carried 418 changes in total, 288 new codes, 84 deletions, and 46 revisions. Most of those were proprietary lab analyses, Category III technology codes, and a surgical-code rebuild. A typical psychiatric practice bills 8 to 12 CPT codes in a year, and in most years the annual churn misses all of them.

Do the core psychiatry codes change in 2027?

No 2027 change has been announced for any core psychiatry code. As of drafting, the early releases and the CY2027 proposed rule's addenda contain no revision to 90791 or 90792, no change to the psychotherapy codes (90832, 90834, 90837) or the add-ons (90833, 90836, 90838 alongside an E/M code), and no change to the office-visit ladder that includes 99214. The September release settles this for good; until then, this is a strong signal rather than a guarantee.

The 98000-series telehealth codes also look unchanged for 2027. Medicare has refused to pay 98000-98015 in both the CY2025 and CY2026 final rules (it pays only 98016), and none of the published summaries of the CY2027 proposed rule suggest a reversal. The default coding advice for a telehealth superbill carries forward into January: 99202-99215 with modifier 95 or 93, and a 98000-series code only for payers you have confirmed individually.

Juan Rodriguez, MD, who reviewed this article, puts the clinical side plainly: "Nothing about January 1 changes how you practice. Keep documenting total time and medical decision-making the way you did in December, and a code-set update stays a fee-schedule edit instead of a chart problem."

What is the adaptive behavior (ABA) revision, and does it affect you?

For most solo psychiatric practices, the ABA revision changes nothing on the superbill; it matters if you supervise adaptive behavior services or coordinate care for autistic patients whose families will ask about coverage. The CPT Editorial Panel approved the change in September 2025 on an application from the ABA Coding Coalition: six new codes join the family, the descriptors of 97151-97158 are revised, and the temporary codes 0362T and 0373T are deleted, all effective January 1, 2027. The revised descriptors became public through the CY2027 Medicare proposed rule's addenda in July 2026; the six new code numbers publish with the full 2027 set, so any list of specific new numbers you see before then is speculation.

What is Medicare proposing for 2027 that touches behavioral health?

The CY2027 Medicare Physician Fee Schedule proposed rule, released July 14, 2026, is a proposals document, and everything in it can move before the final rule lands around November 1. The pieces relevant to a psychiatric practice:

• Payment rates. The proposed conversion factor for clinicians outside advanced payment models is $32.8409, a 1.68% cut from 2026 (a separate $33.1693 factor applies to qualifying APM participants). Even an opted-out cash practice feels this indirectly, because out-of-network plans benchmark their allowed amounts to Medicare; the mechanics are covered in why the Medicare fee schedule still sets your patients' reimbursement.
• G2211 becomes a percentage. CMS proposes converting the office-visit complexity add-on G2211 from a separately billed code into a percentage-based adjustment (16% on the E/M payment for most clinicians, 32% in certain ACO tracks). This matters only if you kept Medicare patients.
• Behavioral health payment increases. The rule proposes higher payment for tobacco-cessation counseling and for behavioral health integration and collaborative care management, relevant if you serve as the psychiatric consultant in a CoCM arrangement with a primary care group.
• Telehealth list additions. Five new G-codes are proposed for the Medicare telehealth list, including a group-medical-session code for visits with 2 to 10 patients, and 17 remote-monitoring codes would be bundled into four new G-codes. The code names in the proposal are placeholders until finalized.
• Tele-mental-health in-person requirement stays waived. Per the CMS fact sheet, the rule implements the Consolidated Appropriations Act, 2026, so the in-person-visit requirement for Medicare mental health telehealth does not apply to services furnished through December 31, 2027.

One piece of color from the same rule: CMS opened a request for information asking whether physician payment should stay anchored to CPT at all. Nothing will come of that by January, but it shows how much appetite CMS has for structural change right now.

What should you update on your superbill for January 2027?

For the codes a cash-pay psychiatric practice bills, the January update is a verification pass. When the full 2027 set is out:

• Pull a 12-month code-frequency report from your EHR. For most practices this is 8 to 12 codes: 90791 or 90792 for intakes, 99212-99215 for follow-ups, psychotherapy add-ons, and occasionally 99205 or a 98000-series code.
• Check each one against the 2027 deletion and revision lists. The telephone codes 99441-99443 were deleted for 2025, and superbill templates that kept emitting them handed patients claims that bounced.
• Update your EHR's service list and superbill template before your first January visit. The date of service controls which code set applies, so a December 30 session bills on 2026 codes even if you generate the superbill in January.
• Re-confirm any payer-specific exceptions you rely on, especially commercial acceptance of the 98000-series, since payer policy there has kept shifting since 2025.

If you generate superbills by hand, this is the week stale codes sneak in. On Eureka, superbills pull the CPT code from the visit's own coded record, so the annual update is one service-list edit rather than a hunt through templates. Whatever you use, the goal is the one described in how superbills work: a document the patient's insurer can price without a phone call.

When does the final CPT 2027 code set come out?

Early September 2026, if the AMA holds to its usual schedule; the CPT 2026 set was announced September 11, 2025, and each annual set takes effect the following January 1. The early releases described above are already on the AMA's site, and CMS's final CY2027 payment rule is expected around November 1, 2026. This article will be updated when the full set and the final rule are public, so a September or November Updated date at the top means the numbers below the fold are final rather than proposed.
