CPT 90833, 90836, 90838: Billing Psychotherapy Add-Ons With E/M
90833, 90836 and 90838 add psychotherapy to an E/M visit: 16-37, 38-52 and 53+ minutes, separate from E/M time. Documentation, 90785 and denials.
CPT 90833, 90836 and 90838 are add-on codes for psychotherapy done in the same visit as an E/M service: 16-37, 38-52 and 53 or more minutes, per Medicare contractor guidance. The E/M code goes first, the psychotherapy minutes cannot include E/M time, and the note must show two separate services. In Ona both lines build from one signed note.
Quick answer:
- An add-on never stands alone. It rides on an E/M code, typically an office visit such as 99213 or 99214, billed by a clinician whose license allows E/M.
- The psychotherapy minutes are counted separately from the E/M work. The same minute cannot support both.
- Denials come from three places: missing time, an E/M level the note does not support, and therapy that is not visibly distinct from the medication visit.
What an Add-On Code Means Here
Psychiatric prescribers often do two things in one visit: manage medication and run a stretch of psychotherapy. CPT handles that with a pair, not a single code. The E/M code describes the medical visit. The add-on describes the psychotherapy done on top of it. The CMS National Correct Coding Initiative Policy Manual, Chapter XI (revision January 1, 2026), puts it plainly: there are separate codes for psychotherapy without an E/M service (90832, 90834, 90837) and add-on codes for psychotherapy reported with the appropriate E/M code (90833, 90836, 90838).
Blue Cross and Blue Shield of Texas lists, in its psychotherapy policy CPCP051, the E/M ranges the add-ons are reported with: office and outpatient visits 99202 to 99239, nursing facility visits 99304 to 99316, and home visits 99341 to 99350, with the E/M listed as the primary code.
Time Thresholds for the Add-Ons
The add-ons follow the same time bands as the standalone codes. First Coast Service Options, a Medicare Administrative Contractor, publishes them in its billing article A57520 (revision effective October 1, 2026), and Optum's provider guidance from October 2025 lists the same ranges.
| Add-on code | Pairs with | What it describes (paraphrased) | Psychotherapy minutes | Standalone equivalent (no E/M) |
|---|---|---|---|---|
| 90833 | An E/M code, listed first | Psychotherapy added to an E/M visit, short | 16 to 37 | 90832 |
| 90836 | An E/M code, listed first | Psychotherapy added to an E/M visit, standard | 38 to 52 | 90834 |
| 90838 | An E/M code, listed first | Psychotherapy added to an E/M visit, extended | 53 or more | 90837 |
| 90785 | The psychotherapy add-on or other qualifying code | Interactive complexity | Not timed | Same |
| Under 16 minutes | Nothing | No psychotherapy add-on | Not reportable | Not reportable |
First Coast adds three rules specific to the add-ons. The psychotherapy time does not have to be continuous within the visit. The total psychotherapy time does not include the E/M time. And prolonged service codes cannot be reported when psychotherapy is billed as an add-on to E/M.
Separate and Distinct: What That Means in a Note
LCD L33252 allows an E/M service and psychotherapy on the same day from the same clinician only when they are significantly different and separately identifiable. Optum's October 2025 guidance tells practices to document psychotherapy distinctly from the E/M. In practical terms, a reviewer reading the note should be able to point at two sections and say which is which.
The E/M section carries the medical work: symptoms reviewed in medical terms, medication response and side effects, any exam elements, labs reviewed or ordered, prescribing decisions, and the medical decision making behind the level billed.
The psychotherapy section carries the therapy: the time spent, the specific interventions used, the patient's participation and response, and progress against the treatment plan goals. LCD L33252 is direct that a generic line such as "supportive psychotherapy given" is not adequate.
The time statement belongs to the psychotherapy section only. Something like "Psychotherapy 10:20 to 10:46, 26 minutes" supports 90833 and makes clear that the minutes before 10:20 were the E/M work.
Choosing the E/M Level When Therapy Is Added
The E/M level has to stand on its own. Because the psychotherapy minutes are already claimed by the add-on, they cannot also be counted toward the E/M. Optum's guidance names this as a top error: billing a higher E/M level when the record only supports a lower one, and it tells practices to confirm the medical decision making for the level billed.
That is the real question behind the "99214 90833" searches. 99214 with 90833 is a common, legitimate pair: a moderate-complexity medication visit plus 16 to 37 minutes of therapy. It stops being legitimate when the 99214 is supported only by time that is also the therapy time, or when the note's medical decision making reads like a straightforward refill. Write the E/M first, on its own merits, then add the therapy.
Interactive Complexity With the Add-Ons
90785 can be added to a visit billed as E/M plus a psychotherapy add-on when one of the communication factors in LCD L33252 is documented: maladaptive communication among participants, caregiver behavior that interferes with the treatment plan, a sentinel event that required a mandated report, or play equipment, devices or an interpreter used to overcome a barrier.
Blue Cross and Blue Shield of Texas spells out the limits. 90785 is not reported with an E/M service when no psychotherapy is reported, it is not used for translation or interpretation alone, and a difficult session does not automatically qualify. CGS's Medicare fact sheet adds that interactive complexity is not a factor in choosing the E/M level. First Coast asks that the note show how much time the interactive complexity took when it rides on a timed code.
What Not to Bill Together
- An add-on with a standalone psychotherapy code. Blue Cross and Blue Shield of Texas lists 90832, 90834 and 90837 as not reported with 90833, 90836 or 90838. The visit gets one psychotherapy code, and with an E/M it is the add-on.
- An add-on with a diagnostic evaluation. The NCCI manual states that 90791 and 90792 are not reported with psychotherapy on the same date, and that E/M codes are not reported with either evaluation.
- An add-on with crisis psychotherapy. 90839 and 90840 are listed by Blue Cross and Blue Shield of Texas as not reported with the add-ons.
- Prolonged services with an add-on. First Coast excludes them when psychotherapy is billed with E/M.
Family psychotherapy (90846, 90847) can be reported on the same date as an add-on only when it is a separate and distinct service, per the same Blue Cross and Blue Shield of Texas policy and the NCCI manual's separate-time-interval rule.
Common Denials and the Fix
| What comes back | Usual cause | Fix before the next claim |
|---|---|---|
| Add-on denied, E/M paid | Psychotherapy time missing or under 16 minutes | A required time field in the psychotherapy section of the template |
| E/M downcoded | Medical decision making does not support the level | Write and level the E/M section on its own, before the therapy |
| Both lines questioned on review | Therapy not distinguishable from the medication visit | Two labeled sections in one note, interventions named |
| Add-on rejected | Billed with 90832, 90834 or 90837, or without an E/M line | One psychotherapy code per visit; E/M listed first |
| 90785 denied | Billed for translation, length or difficulty alone | Document which qualifying factor applied |
| Visit not covered | Authorization or eligibility problem | Check coverage and authorizations before the visit |
How Ona Handles E/M Plus Psychotherapy
Ona is an AI-native, all-in-one practice management platform for outpatient practices, from a single psychiatric nurse practitioner to multi-location behavioral health groups with prescribers and therapists on one record. Everything below is on Ona's own feature and help pages.
One note, two sections. Ona note templates are laid out as the note will print, with bracketed placeholders where content varies. A medication management template with a fixed "Psychotherapy" heading and fields for [psychotherapy start time], [psychotherapy end time] and [interventions used] gives every prescriber the same two-section structure. With a recording, Ona fills the fields from what was said, the intake and the chart, and leaves a field visibly empty when the record does not support it. You keep or discard each change, then sign; corrections after signing become amendments with a reason.
Two lines on the claim. Services carry CPT codes, and procedures and services charted on the visit flow into the draft claim, which rebuilds as the chart changes and is priced from your fee schedule. A visit with an E/M service and a psychotherapy add-on service produces both lines, each linked to a diagnosis. Billing rules can require a diagnosis on every line, at least one note before the visit is billed, and custom rules scoped to a payer can block, warn or move a claim to a review bucket when a pattern your payers reject shows up.
Prescribing in the same visit. Ona's e-prescribing embeds DoseSpot in the chart and the visit, at $45 per prescribing practitioner per month, with EPCS for Schedule II to V controlled substances a further $25. Sent prescriptions land back on the medication list, and refill requests and pharmacy alerts arrive in Ona's notification bell. The psychiatry and prescribing practices guide covers the rest of the prescriber workflow.
Coverage before the visit, denials in one queue. Eligibility runs at booking and again in the 48 hours before the visit. Rejected and denied claims sit in separate statuses, payer reasons come back with their adjustment codes, and a denied claim can be corrected as a linked replacement and resubmitted. Out-of-network patients get a superbill from the completed visit, as described in From visit billing to superbill and claim. Clean claims start with a note that already separates the two services.
Frequently asked questions
Can 90833 be billed without an E/M code?
No. 90833, 90836 and 90838 are add-on codes reported only with an E/M service, which is listed first on the claim. Psychotherapy without an E/M visit is billed with the standalone codes 90832, 90834 or 90837 instead.
What are the time requirements for 90833, 90836 and 90838?
Per First Coast, a Medicare Administrative Contractor, 90833 covers 16 to 37 minutes of psychotherapy, 90836 covers 38 to 52 minutes, and 90838 covers 53 minutes or more. The time is psychotherapy time only and does not include the time spent on the E/M service. Under 16 minutes is not reported.
Is 99214 with 90833 a valid combination?
Yes, when both services are documented separately. 99214 must be supported by its own medical decision making or qualifying E/M work, and 90833 by 16 to 37 minutes of psychotherapy that is not also counted toward the E/M. Optum names billing a higher E/M level than the record supports as one of the top documentation errors.
Can I bill 90785 with an E/M and psychotherapy add-on?
Yes, when the note documents one of the qualifying communication factors, such as maladaptive communication among participants or an interpreter or device used to overcome a barrier. Blue Cross and Blue Shield of Texas states 90785 is not reported with an E/M when no psychotherapy is billed, and is not used for translation alone.
Why was my psychotherapy add-on denied?
The usual causes are missing psychotherapy time, time under 16 minutes, an add-on billed alongside 90832, 90834 or 90837, or a note that does not show the therapy as separate from the medication visit. An E/M level the note does not support is the other common problem, and it often brings both lines under review.
How does Ona build the claim for E/M plus psychotherapy?
Each service in Ona carries its CPT code, so an E/M service and a psychotherapy add-on service on the same visit both flow into the draft claim, linked to the diagnoses on the signed note. Billing rules can require a diagnosis on every line and a note before billing. Staff review the draft and submit it.
Next step
Coding guidance in this article is general. Payer rules vary, so confirm add-on rules, time thresholds and E/M requirements with each payer before you bill.
If prescriber claims come back on the add-on line, start with the template: two labeled sections and a required psychotherapy time field fix most of it. See e-prescribing and billing in Ona, check seats on the pricing page, or start the 14-day free trial with no credit card.
