A psychiatrist can provide genuinely appropriate psychotherapy during a medication management visit and still lose reimbursement, not because the care was wrong, but because the code selected, the documented time, or the payer’s specific requirements didn’t line up with what actually happened in the room.
90833, 90836, and 90838 exist specifically for this scenario: psychotherapy delivered alongside an evaluation and management service on the same day. Getting them right means separating psychotherapy time from E/M time in both the clinical work and the documentation, not just picking a code based on how long the whole appointment ran.
We review these claims regularly. This guide covers how the three codes actually differ, what genuinely counts as psychotherapy time, the documentation that defends each code, and where these claims most often go wrong.
QUICK ANSWER
CPT 90833, 90836, and 90838 are add-on codes for psychotherapy performed on the same day as an evaluation and management service, typically medication management. They represent 30, 45, and 60 minutes of psychotherapy, reported alongside the E/M code rather than in place of it. The psychotherapy component itself, not the total appointment length, determines which add-on code applies, and documentation has to clearly separate the psychotherapeutic work from the E/M work.
KEY TAKEAWAYS
• These are add-on codes billed alongside an E/M service; they represent 30, 45, and 60 minutes of psychotherapy specifically, not the total visit length.
• Psychotherapy time and E/M time are clinically and documentation-wise distinct; medication review and clinical decision-making count toward E/M, not the add-on.
• A claim can be technically coded correctly and still be hard to defend if the note doesn’t clearly separate psychotherapy content from E/M content.
• Payer rules for these combinations vary; never assume a Medicare policy applies identically to every commercial plan.
• Repeatedly resubmitting a denied claim without identifying the root cause wastes time without fixing anything.
• The goal is accurate billing, not maximizing reimbursement; both underbilling and overbilling create real problems.
• Pre-bill quality control prevents far more denials than working them after the fact.
CPT 90833 vs. 90836 vs. 90838
CPT | Psychotherapy Time | Used With | Common Risk |
90833 | 30 minutes | E/M service, same day | Time or E/M relationship not clearly documented |
90836 | 45 minutes | E/M service, same day | Documentation defaults to a template, not the session |
90838 | 60 minutes | E/M service, same day | Longer time claims draw closer scrutiny if notes are generic |
How to Determine the Correct Code
Was psychotherapy actually performed, distinct from the E/M work? Was an applicable E/M service also provided that day? Is the psychotherapy component documented on its own terms, not folded into the E/M note? Does the documented psychotherapy time support the specific add-on code? Does the payer’s policy permit this combination? Does the claim contain every element the payer expects? A code shouldn’t be selected because it reimburses more — it should reflect what the documented time actually supports.
What Counts as Psychotherapy Time?
Total appointment length and psychotherapy time are not the same number, and treating them as interchangeable is one of the most consistent sources of coding risk in this code family. Psychotherapy time covers the psychotherapeutic intervention itself. It doesn’t include medication review, history-taking for the E/M portion, clinical decision-making about the medication regimen, or administrative time.
Example: A 60-minute visit might break down as 30 minutes of E/M work, medication review, side effect discussion, dosage decisions, and 30 minutes of psychotherapy intervention. That visit supports the E/M code plus 90833, not 90838, even though the total appointment ran a full hour. This is illustrative only; actual code selection always depends on what happened and what was documented.
Documentation Requirements Across All Three Codes
The documentation standard scales with time and complexity, but the core elements stay consistent:
☐ Clinical reason for psychotherapy, distinct from the E/M reason
☐ Medical necessity for the psychotherapy specifically
☐ The psychotherapy intervention or therapeutic approach used
☐ Psychotherapy time, documented separately from E/M time
☐ Patient response to the intervention
☐ Progress toward treatment goals
☐ Clear separation from the E/M documentation, not blended into one narrative
☐ Provider authentication and signature
Expert Insight: The strongest psychotherapy claims aren’t the most aggressively coded ones. They’re the claims where the clinical service, documentation, CPT selection, diagnosis, and claim data all tell the same story.

Most Common Billing Errors
Error | Consequence |
Using total visit time instead of psychotherapy time | Code overstates what was actually psychotherapeutic work |
Add-on billed without an appropriate E/M service | Claim rejected for a missing required relationship |
Documentation doesn’t distinguish the two services | Claim hard to defend even if coded correctly |
Missing or insufficient time documentation | Denial or downcoding on review |
Generic, copy-forward notes | Doesn’t reflect the individual session, audit risk |
Unsupported medical necessity | Denial regardless of correct time and code |
Incorrect payer assumptions | Applying one payer’s rule to a different plan |
Repeated denials without root-cause review | Same denial recurs claim after claim |
Medicare vs. Commercial Insurance
Never assume all commercial payers handle this combination identically, or that a Medicare rule transfers directly to a commercial plan. Confirm current policy with each payer.
Denial Management for These Codes
Denial Reason | Likely Cause | Corrective Action |
Missing E/M relationship | Add-on billed without a qualifying E/M code on the claim | Confirm the E/M code is present and appropriate |
Documentation mismatch | Note doesn’t clearly support the billed add-on | Review the note against the specific code’s requirement |
Time mismatch | Documented time doesn’t support the code billed | Reconcile documented psychotherapy time before resubmitting |
Medical necessity | Diagnosis and plan don’t support the psychotherapy | Confirm necessity is documented, not assumed |
Payer policy | Combination not covered under this specific plan | Verify current payer policy before resubmitting |
Claim-edit issues | System-level rejection, not a clinical issue | Reconcile claim data before resubmission |
Don’t repeatedly resubmit a denied claim without fixing the underlying problem — the same denial will just recur.
Pre-Bill Quality Control Workflow
Documentation received → code review → E/M relationship verified → psychotherapy time validated → diagnosis and medical necessity reviewed → payer requirements checked → claim scrubbed → claim submitted → payment monitored → denial analyzed → appeal or recovery when appropriate. Most of the value in this workflow sits before submission, not after.
Psychotherapy Billing Audit Checklist
☐ Correct CPT code selected
☐ Appropriate E/M relationship confirmed
☐ Psychotherapy clearly documented, separate from E/M
☐ Time adequately supported in the note
☐ Medical necessity established
☐ Diagnosis appropriate and current
☐ Provider credentials verified
☐ Payer policy reviewed for this specific combination
☐ Claim accurately populated
☐ Denials tracked by root cause, not just resubmitted
Reduce psychotherapy claim denials.
Revenue Leakage: Underbilling vs. Overbilling
Underbilling: failing to report legitimately supported psychotherapy add-ons, missing services the documentation actually supports, or avoiding a code out of denial fear rather than documentation confidence.
Overbilling: claiming time that isn’t supported, selecting a longer code than the session actually involved, or billing based on total appointment length rather than documented psychotherapy time.
The goal is accurate billing, not maximizing reimbursement in either direction.
Quick Reference: What to Check
Question | What to Check |
Was psychotherapy performed? | Confirm a genuine psychotherapeutic intervention occurred |
Was E/M also provided? | Confirm a qualifying E/M service is on the claim |
Is psychotherapy time documented? | Confirm time is separate from E/M time in the note |
Is medical necessity supported? | Confirm diagnosis and plan support the psychotherapy |
Does the payer cover the combination? | Verify current policy for this specific payer |
Does the claim match the record? | Confirm coded data reflects the actual documentation |
Is authorization required? | Verify per payer; not universal |

Yes, that’s specifically what they’re designed for; they’re not billed as standalone codes.
Q6. What documentation is required for CPT 90833?
Documentation showing the psychotherapy intervention, time, patient response, and medical necessity, clearly separated from the E/M portion of the note.
Q7. What documentation supports CPT 90836 and 90838?
The same core elements as 90833, scaled to the longer documented time, with equally clear separation from the E/M work.
Q8. Why are psychotherapy add-on claims denied?
Missing E/M relationships, time documentation that doesn’t support the code, unclear separation between psychotherapy and E/M content, and unsupported medical necessity are common causes.
Q9. How should psychotherapy time be documented?
Separately from E/M time, reflecting only the actual psychotherapeutic intervention, not the total appointment length.
Q10. How can behavioral health practices reduce psychotherapy billing denials?
Validate the E/M relationship and time documentation before submission, keep psychotherapy and E/M documentation clearly distinct, and track denials by root cause rather than simply resubmitting.
