CPT code 90836: Psychotherapy add-on billing guide (2026)

Key takeaways

CPT code 90836 covers 38 to 52 minutes of psychotherapy delivered on the same date as an evaluation and management service.

It never bills on its own. A primary E/M code such as 99213 or 99214 must appear on the same claim.

Medicare bars time-based E/M selection when a psychotherapy add-on is reported, so the E/M level rests on medical decision-making.

Recorded start and stop times, therapy content written apart from the E/M note, and medical necessity keep the add-on payable.

Practice management software like Pabau supports the documentation and electronic claim submission behind paired psychotherapy visits.

CPT code 90836 covers 38 to 52 minutes of psychotherapy delivered in the same visit as an evaluation and management (E/M) service. It is an add-on code, so it never travels alone. A primary E/M code has to sit beside it on the same claim, for the same date.

That one rule drives most 90836 denials. The rest usually trace back to a note that blends the therapy into the medical visit. Bill it cleanly and the add-on pays on top of the primary visit.

What follows covers the time rules, E/M pairing, documentation, 2026 Medicare pay, modifiers and the costliest errors.

CPT code 90836 never travels alone

The plus symbol beside 90836 in the American Medical Association’s CPT code set marks it as an add-on. Payers read it as an extension of a medical visit, not as a therapy session in its own right. That single fact controls how the claim is built.

Three add-on codes behave this way. 90833 covers 16 to 37 minutes of psychotherapy, 90836 covers 38 to 52, and 90838 covers 53 or more. None of them clears a claim edit without a primary E/M code filed for the same day.

One row breaks the pattern. 90837 is standalone psychotherapy of 53 minutes or more, reported when no E/M service happens that day. That fork gets its own section further down.

Only the therapy minutes count toward 38 to 52

Count the psychotherapy segment, not the appointment. The medical work and the therapy work run on two separate clocks, and only the second one decides which add-on code you report.

• What counts: face-to-face or telehealth psychotherapy with the patient, including cognitive behavioral, supportive and psychodynamic work
• What does not: medication review, mental status exam, lab review, charting and care coordination, which all belong to the E/M
• Floor and ceiling: 38 minutes to reach 90836. At 53 minutes of therapy the code becomes 90838
• The proof: start and stop times for the therapy segment, written in the note. “Therapy was provided” fails a payer review

Take a 60-minute integrated visit. Medication review, a side-effect check and a brief exam run 13 minutes. Psychotherapy fills the other 47. That visit bills as an E/M plus 90836, and the note has to show both clocks.

Most psychiatrists run the E/M first and the therapy second. Marking the moment the visit changes gear takes one line, and it settles any later question about the split.

No E/M privileges, no 90836

Only a provider who can bill an E/M service can bill 90836. Psychotherapy training on its own is not enough, because the add-on hangs off a medical visit that somebody has to own.

• Psychiatrists (MD/DO): the usual biller, qualified for the E/M and the psychotherapy alike
• Nurse practitioners: eligible where state scope covers prescribing and psychotherapy, subject to payer credentialing
• Physician assistants: eligible under physician supervision, in states that permit PA-delivered psychotherapy
• LCSWs and LPCs: generally cannot bill E/M codes alone, which rules out 90836. Their sessions bill as standalone psychotherapy

Credentialing varies more than scope does. A nurse practitioner cleared for 90836 by one commercial plan may not be cleared by the next. Settle it at the payer level before the first claim goes out, not after the first denial.

Picking the E/M code that carries the claim

The E/M code is the claim’s primary line and 90836 rides on top of it. Established patients usually pair with 99213, 99214 or 99215. New patients pair with 99204 or 99205.

CPT 99214 is the workhorse of the group. It fits the moderate-complexity established patient, which is what a medication-plus-therapy visit usually looks like.

Then comes the rule that catches experienced coders. When a psychotherapy add-on is on the claim, Medicare does not let time drive the E/M level.

Its billing and coding article for psychiatry and psychology services, A57480, states it directly. Choose the E/M on medical decision-making, and leave every therapy minute with the add-on.

Two services, two notes, or the add-on gets denied

The chart has to show two services documented separately inside one encounter. An auditor who cannot see where the E/M ends and the therapy begins denies the add-on, often at pre-payment review.

• Start and stop times: clock times for the therapy segment, not “about 40 minutes”
• Therapy content: the modality used and how the patient responded, written apart from the medication and symptom notes
• Medical necessity: why psychotherapy was clinically indicated at this visit, alongside the E/M
• Diagnosis: an ICD-10-CM code that supports both services, such as F32.1 for moderate major depressive disorder
• E/M support: medical decision-making that stands on its own, with no borrowed therapy minutes
• Provider credentials: an NPI whose credential covers the medical visit and the therapy

One shortcut undoes all of it. A therapy note that says “see above” folds the two services back into one, and the add-on falls with it.

What Medicare pays for the add-on in 2026

Medicare’s national non-facility rate for 90836 sits at approximately $83 in 2026. That figure comes from the code’s total non-facility RVU of 2.49 and a conversion factor near $33.40.

Treat it as a working estimate rather than a pinned lookup value. The paired E/M code is reimbursed separately, on top.

Your locality moves the number. The geographic practice cost index adjusts each component. Run the code through the CMS Physician Fee Schedule lookup tool for the rate your practice will see.

Medicaid is the weak spot. Some state programs pay add-on psychotherapy codes alongside an E/M, some ask for prior authorization, and some do not cover them at all.

Read your state billing manual before 90836 goes on a Medicaid claim.

Where modifiers apply, and why GT no longer does

An in-office 90836 usually needs no modifier at all. Two situations change that. One is a telehealth visit. The other is a payer that wants the E/M flagged as separately identifiable.

The GT row is where older billing guides go wrong. CMS retired GT for Medicare Part B professional claims in 2018, and it now belongs to Critical Access Hospital Method II institutional billing. Putting it on a professional psychotherapy claim dates the claim by eight years.

Professional telehealth claims identify the setting through the place of service code instead. POS 02 covers telehealth delivered outside the patient’s home, and POS 10 covers telehealth at home.

Check current CMS telehealth guidance and each commercial payer’s own policy before you submit, because plenty of plans still run their own rules.

How a 90836 claim travels from note to payment

No single step here is hard. The trouble is that four elements have to line up at once: two codes, one date, one time threshold and two blocks of documentation. This is the path a clean claim takes.

1. The visit. The clinician runs the E/M, then the therapy, and records a start and stop time for the therapy segment
2. The note closes. Medical decision-making supports the E/M level. The therapy content sits in its own section, under its own heading
3. Charge capture. The E/M goes on the claim as the primary line. 90836 goes underneath it, same date of service
4. Scrubbing. Claim edits confirm a primary code accompanies the add-on and that the diagnosis supports both lines
5. Submission. The claim leaves for the clearinghouse, which routes it to the payer and returns an acknowledgment
6. Remittance. The remittance advice posts both lines. A paid E/M next to a denied add-on is the pattern to watch for

Before you submit: Five things to check

• A primary E/M code is on the claim, carrying the same date of service as 90836
• The therapy start and stop times appear in the note, as clock times
• The therapy content has its own section, with no cross-reference to the E/M
• The E/M level rests on medical decision-making, not on time
• Telehealth visits carry the right place of service code and, where required, modifier 95

Six mistakes that get 90836 denied

Denials on this code repeat themselves. Six mistakes account for most of them, and each has a fix that costs nothing to apply.

• No primary E/M on the claim. Claim edits catch this instantly, and nothing reaches a human reviewer
• Time recorded as a duration. “45 minutes of psychotherapy” is not proof of service. Clock times are
• A blended note. One narrative covering both services gives the auditor nothing to separate, so the add-on goes
• The wrong tier. 35 minutes is 90833 and 55 minutes is 90838. Read the documented time before you pick
• 90836 filed as a primary code. It fails at the edit stage every single time
• A stale telehealth modifier. GT on a professional Medicare claim is the most common version of this

When the same code keeps bouncing, pull the last 90 days of 90836 claims and sort the rejections by reason. The remittance codes tell you which of the six you have, and our medical billing denial codes reference explains what each one means.

90836 or 90837? The E/M decides

Ask one question. Did anyone bill an E/M service for this patient on this date? If yes, the therapy is an add-on and 90836 is in play. If no, and the session ran 53 minutes or longer, 90837 is your code.

Getting this backwards costs money in both directions. Reporting 90837 on a day when an E/M also happened misrepresents the visit and invites recoupment. Reporting 90836 with no E/M on the claim simply fails the edit.

90833, 90836, 90838: The clock picks the code

All three add-ons need a same-day E/M. Only the length of the therapy segment separates them, which makes accurate timing the whole game. The bands sit end to end, with no space between them.

Undercoding is the quiet problem in this family. A practice billing far more 90833 than 90836 is usually recording therapist time loosely, not running shorter sessions. Medication review rarely fills more than 15 minutes of a 60-minute integrated appointment. The other 45 sit squarely in 90836 territory, and 90833 gives that work away.

Full descriptor text for each code in the add-on family sits in the AAPC CPT code lookup. It is worth a check whenever a payer questions the tier you chose.

How Pabau keeps paired psychotherapy claims complete

Most practices assemble a 90836 claim in two places. The therapy note lives in the chart. The codes get keyed into a billing system afterward, often by somebody who was not in the room. Time fields get skipped and the add-on goes out thin.

Practice management software like Pabau closes that distance. Notes, coded services and the claim sit in one patient record, so the E/M and the add-on leave together with their documentation attached.

Pabau’s claims management software submits electronically through Claim.MD, our US clearinghouse partner, and posts the remittance back against the same visit.

Coding stays a human job. Nobody picks the E/M level or the add-on tier for you, and no software counts your therapy minutes.

What changes is that documentation, coded lines and submission stop living in three separate systems, so the claim leaves the practice complete the first time.

Keep psychotherapy add-on claims complete

Pabau holds the therapy note, the coded lines and the electronic claim in one patient record. Paired E/M and psychotherapy visits leave your practice documented and ready to pay.

Conclusion

The rules around 90836 are short. What makes the code unforgiving is that all of them have to hold at once, on one claim, on one date, in one note. Miss the E/M, the clock times or the separation between the two services, and the add-on comes back.

So fix it upstream. Capture start and stop times in the template. Choose the E/M on medical decision-making. Scrub for a primary code before the claim goes out. Appeals are a poor substitute for a note that was right the first time.

The add-on line is only as good as the note behind it. Book a demo to see how Pabau keeps the therapy note, the coded lines and the claim in one place.
