Behavioral health billing is not just about picking the right CPT code. The documentation in the patient record needs to support the service too. This is important with CPT 90836 because the code covers psychotherapy done along with an evaluation and management service.
The note does not have to be very long. It just needs to explain what took place during the session. Someone reviewing the chart should be able to see what the provider worked on, how the patient responded and why the service made sense for that visit.
What Is CPT 90836?
CPT 90836 is an add-on code for psychotherapy provided with an evaluation and management service. The psychotherapy time generally falls within the 38 to 52 minute range. An appropriate E/M code also needs to support the same encounter.
This is where documentation can get a little confusing. A provider can handle psychotherapy and E/M work during one visit but the record still needs to support both. A visit that was scheduled for 45 minutes does not automatically mean 90836 is the right code. The actual service and documented time need to support the code used.
What Should the Documentation Show?
A good note should give a quick picture of the session. What did the provider and patient talk about? What did the provider work on? And how did it relate to the patient’s treatment? Those are the things that should come through when someone reads the record.
With CPT 90836, the note should include the psychotherapy time along with the main concerns and the work done during the session. The provider should also note how the patient responded, any progress related to the treatment goals and what comes next. When an E/M service is part of the same visit, that work needs to have support in the record too.
The need for behavioral health services is also fairly large. According to SAMHSA, 23.4% of U.S. adults, or about 61.5 million people, had a mental illness in 2024. That makes clear and accurate documentation even more important as behavioral health services continue to be provided on a large scale.
The note does not need every detail from the session. Just include enough to show what was discussed, what the provider did and how it connects to the patient’s treatment. They just need enough information to understand what the visit was about and what service the provider actually delivered.
Document the Psychotherapy Time
Time is one of the first things a billing team may look for. CMS guidance allows providers to record psychotherapy time using start and stop times or the total psychotherapy time. The psychotherapy time should not get mixed together with time spent on the E/M service.
Writing “60-minute session” does not really explain how the time was used. If the provider also performed an E/M service, the note should make it easier to tell which time relates to psychotherapy.
There is no need to write out every minute of the appointment. Just document the psychotherapy time clearly and keep it separate from the E/M work.
Describe the Therapy That Took Place
Some notes end up being too general. Phrases like “therapy provided” or “discussed patient’s concerns” do not really explain what happened during the session.
The provider should mention what they worked on and what type of intervention they used. This could be cognitive restructuring, coping skills, behavioral strategies, supportive therapy or problem-solving. It depends on what the patient needed during that session.
There is no reason to write down the full conversation. A few useful details about the therapy are enough to give the note some context.
Instead of just writing that anxiety was discussed, the provider can say they worked with the patient on identifying anxious thoughts and finding a coping strategy for situations that trigger them.
Connect the Session to Treatment Goals
The progress note should have some connection to the patient’s treatment goals. This helps show that the session was part of the patient’s ongoing care and not just a general conversation.
A patient may have a goal related to managing anxiety. During the session, the provider might help the patient identify triggers or practice a coping technique. The note can briefly explain how that work relates to the goal and what changed, if anything.
Progress will not look the same in every session. A patient might report some improvement. Another patient may still be struggling or may have faced a new problem during the week. That is fine. The note should describe what really happened instead of trying to make every visit sound positive.
Include the Patient's Response
The note should not only talk about what the provider did. It should also give some idea of how the patient responded during the session.
Maybe the patient understood the technique. Maybe they had trouble using a coping strategy. They may have identified a new concern or realized something about a pattern they had not noticed before.
Try not to rely only on phrases such as “patient participated well.” That does not give much information by itself. A brief note about how the patient responded can make the record more useful.
The provider could mention that the patient identified situations that increase anxiety and agreed to practice a coping technique before the next session.
Support Medical Necessity
The documentation should make it clear why psychotherapy was needed for the patient. It should connect the patient’s symptoms or condition with the work done during the session.
This does not mean copying the patient’s entire history into every progress note. That would take more time and still may not tell the reviewer what happened that day.
Instead, focus on the current concerns. If symptoms are affecting the patient’s daily life, the note can explain how the session addressed them. If the patient is working toward a specific goal, the provider can show how the session fits into that goal.
The reason for the service should be fairly easy to understand from the record.
Keep the E/M Documentation Clear
Another point to watch with CPT 90836 is the evaluation and management part of the visit. Since 90836 is an add-on code, the documentation should support the E/M service reported with it.
The psychotherapy section should show the psychotherapy time and work performed. The E/M documentation should support the evaluation and management work the provider completed.
These do not always need to appear as two completely separate notes. The important thing is that the record makes the different parts of the visit clear.
This can save time during a chart review too. When the documentation is easy to follow, billing and compliance teams are less likely to need clarification from the provider.
Common Documentation Problems
Documentation gaps are often small. Still, when the same gaps happen across many records, they can become a bigger issue. Some common problems include:
- Missing psychotherapy time: The note does not clearly show how long psychotherapy lasted.
- Combined encounter time: The provider lists one total time without making the psychotherapy and E/M time clear.
- Vague intervention details: The note says therapy happened but does not explain what the provider actually worked on.
- No patient response: The note focuses on the provider’s actions but says little about the patient’s response.
- Weak treatment goal connection: The session does not clearly relate to the patient’s treatment plan.
- Repeated template language: Several notes use almost the same wording and do not show what happened during each visit.
- Limited E/M support: The record does not clearly support the E/M service reported with 90836.
Templates can be useful when providers have a lot of notes to complete. The problem starts when the same wording gets copied into every visit. A template should give the provider a starting point, not fill in the whole story for them.
How Chart Audits Can Help
Regular chart audits can help behavioral health organizations find these problems before they turn into repeated billing issues. Instead of waiting for a payer to question a claim, the team can review a sample of records and see where providers are having trouble.
An audit may show that several providers document interventions well but often forget to separate psychotherapy time from E/M time. Another provider may document the time correctly but rarely include the patient’s response.
That gives the organization something specific to work on. Training can focus on the actual gap instead of giving everyone another general reminder about documentation.
Chart audits by Binario can also show whether the current documentation template is working. If providers keep missing the same information, the template itself may need to be reviewed.
Tips for Better CPT 90836 Documentation
Good documentation does not have to take a huge amount of time. Providers can make things easier by writing the note while the session is still fresh in their mind. A simple template can help too, as long as the provider changes the details to match the actual visit.
Keep the wording straightforward. Include the information that matters and leave out details that do not support the service. It also helps to check the note before signing it.
A quick review can cover the main points:
- Is the psychotherapy time documented?
- Does the note explain what was addressed?
- Is the intervention clear?
- Did I include the patient’s response?
- Does the session connect to the treatment goals?
- Is medical necessity clear?
- If an E/M service was reported, does the documentation support it?
These checks only take a moment and can help catch small gaps before the record goes to billing.
Final Thoughts
Good documentation makes behavioral health billing easier to support and chart reviews easier to handle. With CPT 90836, the record should show the psychotherapy time, what the provider worked on, how the patient responded and how the session fits into the treatment plan.
The E/M part matters too since 90836 is an add-on code. Keeping the documentation clear can help avoid questions later. Keeping the two parts of the encounter clear can prevent confusion later.
The goal is not to make every note longer. It is to make each note useful and accurate. When the documentation reflects the actual session, providers, billing teams and compliance staff all have a better record to work with.
