DAP vs BIRP vs GIRP notes: what each format carries, with one session written three ways

By Selam Koch, PMHNP-BC, founder of OneStep Scribe and practicing psychiatric nurse practitioner. Published August 2026.

In an agency, your note format was probably chosen for you. In private practice, you chose it yourself, possibly by keeping whatever your first supervisor used. Either way, DAP, BIRP, and GIRP are the three structures most therapy notes live in, and the differences are not cosmetic. Each format leads with a different question: what happened, what did you do, or what goal were you working toward, and that leading question shapes what the note makes obvious and what it quietly buries.

This guide walks through each acronym section by section, explains when each fits, then documents the same fictional anxiety-management session in all three formats so you can compare them line by line. It closes with what matters regardless of format: the medical-necessity content payers look for, which no acronym supplies on its own.

What each acronym stands for

DAP: Data, Assessment, Plan

DAP is the leanest of the three. Data holds everything that happened: what the client reported, what you observed, and what occurred in the session, including the interventions you used. Assessment is your clinical interpretation: what the data means, how the client is progressing against the treatment plan, and how they responded to the work. Plan is what happens next: homework, referrals, frequency, and the focus of the next session.

DAP is essentially a SOAP note with the subjective and objective sections merged. That merge is its strength and its weakness. It writes fast and reads naturally, but because the interventions live inside Data alongside everything else, a reviewer has to hunt for what you actually did.

BIRP: Behavior, Intervention, Response, Plan

Behavior covers the client's presentation: reported symptoms, observed affect and behavior, and relevant status items such as risk screening. Intervention is its own section, and that is the point of the format: the specific clinical methods you used, named, get a dedicated home. Response records how the client responded to those interventions in the session. Plan closes the note as usual.

By separating intervention from everything else, BIRP makes the skilled-service question, "what did the clinician do that required a clinician," impossible to miss. That is why it dominates in community mental health and other publicly funded settings where notes are reviewed for medical necessity at volume.

GIRP: Goal, Intervention, Response, Plan

GIRP keeps BIRP's middle and swaps the opening. Goal states which treatment-plan goal or objective the session addressed, ideally in the treatment plan's own language. Intervention, Response, and Plan then work exactly as they do in BIRP.

The format forces every note to begin by connecting the session to the treatment plan, which is exactly what auditors in goal-driven programs check first. Its structural gap is the mirror image of its strength: there is no dedicated presentation section, so symptom status and observations have to be folded into Goal or Response deliberately or they disappear from the record.

When each format fits

Three practical rules sit on top of that table. First, if your agency or program specifies a format, use it; the mandate usually reflects what their auditors and payers check. Second, if you choose freely, choose for your weakest documentation habit: clinicians who under-document their own interventions get a real guardrail from BIRP, and clinicians whose notes drift from the treatment plan get the same guardrail from GIRP. Third, keep one format consistent within a chart; a record that switches structure every few sessions reads as improvised.

The headings work as documentation cues: each asks a question the note must answer before you sign. That is the honest case for structured formats. The dishonest case, that any format is "audit-proof," is not true of any of them, for reasons covered below.

One session, three formats

The examples below document the same fictional session so the formats can be compared directly; every detail is synthetic. J.M. is an adult in weekly outpatient CBT for generalized anxiety disorder, with a treatment-plan goal of reducing avoidance of anxiety-provoking work tasks. In the session, the therapist reviewed a completed thought record, used cognitive restructuring on a catastrophic prediction about an upcoming work presentation, practiced diaphragmatic breathing, and set a graded homework task. GAD-7 today: 11, down from 15 at intake. Each version opens with the same administrative anchor line, because the date, time, service code, and signature belong in every real note whatever the format; they are part of the payer checklist covered later in this guide.

What every format still owes the payer

No format is audit-proof, because payers review content, not headings. In my chart-review experience and in published payer guidance, reviewers of outpatient psychotherapy notes look for the same elements whatever the structure. Payer policies vary in emphasis and wording, so verify specifics with the plans you bill, but the recurring list looks like this:

• A diagnosis the session ties to. The note should make clear the work addressed the diagnosed condition, not general life coaching.
• Linkage to the treatment plan. The session should visibly serve a current plan goal. GIRP forces this; DAP and BIRP writers have to add it on purpose.
• A named clinical intervention. "Provided support" and "discussed stressors" describe a conversation anyone could have. "Cognitive restructuring targeting a catastrophic prediction" describes skilled service. BIRP and GIRP force a dedicated section; DAP writers must keep it visible inside Data.
• The client's response and progress. Evidence the treatment is doing something, or an explanation and plan change when it is not.
• A forward plan. Continued frequency, homework, and focus, which together justify the next authorized session.
• The administrative anchors. Date, session start and stop times or duration, service code, and signature. Time is what distinguishes the individual psychotherapy codes from one another, so record it in the note, and verify current code definitions with your payer.

What a reviewer is really tracing is one documented line connecting the diagnosis, the treatment-plan goals, the session's interventions, and the client's progress. When those four link up across notes, the chart is far easier to defend in any format; when they do not, no acronym saves it. Risk documentation follows the same logic: a brief screen belongs in every note's presentation section, whatever that section is called.

SOAP: the psychiatric-prescriber cousin

If you share patients with a psychiatric prescriber, their notes probably follow SOAP: Subjective, Objective, Assessment, Plan. SOAP is DAP with the Data section split in two, and the split exists because prescribers carry data therapists usually do not: vital signs, labs, medication lists, and a formal mental status exam all need an Objective home separate from what the patient reports. The full structure, with a complete worked example, is in the psychiatric SOAP note example, and the broader anatomy of a prescriber follow-up note is in the psychiatric progress note example.

Reading across the fence is worth five minutes: a therapist's Response section and a prescriber's Assessment section do the same medical-necessity work in different dialects. For the visit where the two roles meet, the intake evaluation, the coding split is covered in 90791 vs 90792, a distinction that matters to therapists and prescribers alike.

Frequently asked questions

Do payers require DAP, BIRP, or GIRP specifically?

Generally no. Payers publish content requirements rather than mandating a format; any structure that reliably carries the elements above can satisfy them. Format mandates usually come from agencies, programs, or state contracts. Verify with your specific payer and program, since some publicly funded programs do name a structure.

Can I switch formats for an existing client?

Yes. Switch at a natural boundary, such as a treatment-plan review, and then stay consistent; a chart that changes structure repeatedly is harder for a covering clinician or reviewer to follow.

Which format is fastest to write?

DAP, usually. But the honest measure is speed to a defensible note, not speed to any note. If DAP speed comes from letting interventions blur into "processed feelings," the time saved can come back as denied claims and record requests. BIRP and GIRP are slower by a sentence or two and harder to write badly.

Can an AI scribe write DAP, BIRP, or GIRP notes?

Yes, and format is the easy part; grounding is the hard part. OneStep Scribe listens to the session and drafts the note in the structure you use, with the interventions you delivered named and the client's response captured, and it is built to flag content it cannot tie back to the conversation. Nothing enters the chart until you review, edit, and sign. What to demand from any vendor is covered in choosing an AI scribe as a therapist.
