What are CMS documentation requirements for psychotherapy?
What Medicare expects in an outpatient psychotherapy note: time that supports the CPT code, a named intervention, medical necessity, and a signature that counts.

Scheduling & billing
The appointment, the note, and the claim are the same event.
Mental health scheduling that understands session length and caseload, claims assembled from documentation you already signed, and remittances that post themselves instead of waiting in a portal you keep meaning to check.
How does mental health billing work in an EHR?
A billable session begins as a calendar appointment. Once the note is signed, the EHR holds everything a claim requires: the CPT code matching the service and its duration, the ICD-10 diagnosis carried from the treatment plan, the place of service, and the rendering provider. It assembles an 837P, transmits it through a clearinghouse, and posts the ERA against the charge when the payer responds.
Practices that bill insurance without this usually maintain the same information in three places — a scheduler, a note, and a billing service — and reconcile them by memory. Congruent's claims, eligibility checks, and ERA posting are on the $29 Practice plan. Claims are $0.40 each, from the first one, and ERA posting and eligibility checks are included in that price.
The calendar
A scheduler that knows a 53-minute hour is not a 45-minute one.
Generic calendars treat every booking as a block of time with a name attached. That is fine until the difference between 90834 and 90837 turns on whether the session ran to 53 minutes, and the only record of what actually happened is a note written four hours later that says "session held."
Here the appointment carries its intended code and duration from the moment it is booked, the note records what really happened, and the two are compared before anything is billed. The 10 a.m. that ran short becomes a question at signing rather than a recoupment eighteen months on.
- Appointment types carry their CPT code and expected duration from the start
- Reminders by text and email, with the no-show and late-cancel policy applied consistently
- Real-time eligibility checked before the intake, not discovered at the first denial
- Recurring caseload, waitlist, and shared availability across a group practice

Claims
An 837P is a summary of documentation you already wrote.
Every field on a professional claim already exists somewhere in the chart by the time you sign the note. Therapy practice billing software that makes you re-enter the diagnosis, re-pick the code, and re-type the date of service is not saving you work — it is making you the integration layer between two halves of one product.
Congruent builds the claim from the signed note, holds anything the documentation cannot yet support, and scrubs for the mistakes that produce most front-end rejections: a diagnosis that is not on the plan, a missing modifier, a code the recorded duration will not carry.

Claim 4474 is held because the note is unsigned. Nothing goes out asserting a service the chart has not documented yet.
Getting paid
The remittance posts itself. The denial gets a worklist.
The part of billing that quietly costs the most is not submission. It is the reconciling — logging into a payer portal, reading an EOB, matching it against charges, working out which of the four lines was underpaid and why, and deciding whether $38 is worth an afternoon.
Congruent posts the remittance against the charge automatically and keeps the adjustment reasons where you can see them. What is left is a short list of things that genuinely need a person: the denial with a reason code, the underpayment worth appealing, the balance that needs a conversation rather than a statement.
- ERA and EOB posted automatically against the charge, with the adjustment reasons kept
- Denials queued with the payer's reason code and the documentation needed to appeal
- Client balances, card processing, invoices, and superbills on both plans
- Claims at $0.40 each, with ERA posting and eligibility checks included
