A DAP note shows medical necessity when a reviewer can see today’s problem, the intervention you actually used, how the client responded, and why another 90834 or 90837 is still indicated. “Client processed feelings; will continue weekly” is a recap. It does not defend the hour. Write Data that can change, an Assessment that names technique and progress, and a Plan that points at a treatment-plan goal.
The field list is in the DAP template. The same thread shows up in SOAP form in psychiatry SOAP notes that support medical necessity.
Put changeable facts in Data
Data is what you observed and what the client reported this session. Interval stressors, sleep, substance use, risk (SI, HI, self-harm urges), and at least one verbatim line if it carries weight.
Do not dump the intake history here. Do not paste last week’s Data with a new date. If nothing changed, say that in one sentence and move the work into Assessment: “Sleep still 4 a.m. waking; no new stressors; PHQ-9 14, same as last visit.”
If you gave PHQ-9 or GAD-7, put the total and the change in Data. A score that never appears in Assessment is decoration.
Time belongs somewhere obvious: start/stop or total minutes. 90834 is 38 to 52 minutes. 90837 is 53 or more. Under 16 minutes is not a psychotherapy code.
Name the intervention in Assessment
Assessment is not a second mood paragraph. Name the treatment-plan goal you worked, the modality, and the specific technique.
“CBT for panic, interoceptive exposure to lightheaded sensation, two 90-second trials” is an intervention. “Supportive therapy” is only acceptable if you then say what you supported and why that was the indicated move today.
Tie the DSM-5-TR or ICD-10 impression to function. Panic with avoidance of driving is a different necessity story than panic that is annoying but not limiting work.
If you are stuck, write three clauses: diagnosis and current severity, what you tried today, what the response implies for the plan.
Show the observed response
Payers look for this more than they look for the theory.
Engagement, resistance, affect shift, skill demonstration, or insight. “Client completed both exposure trials, SUDS 7 to 4 on the second, and agreed to practice in the car this week” is a response. “Client was engaged” is not.
If the client shut down, chart that. A stalled session still supports medical necessity if you name the stall and what you will do with it. Collusion with a dead session (“good work today”) is what looks templated.
Point the Plan at a living goal
The Plan names the between-session assignment, the risk plan if one is active, any coordination with a prescriber, and the next-session focus. Match it to the goal in the treatment plan, not a generic “continue CBT.”
If the goal is “drive to work without pulling over,” the Plan is a driving hierarchy step, not “practice coping skills.” If you changed frequency or modality, say why.
What payers mean by a golden thread is the same test in plainer language: problem, thinking, what you did, what happens next.
Sample DAP that would hold on review
Duration: 53 minutes. CPT 90837. Modality: CBT.
Data
Client reports two panic attacks since last visit, both in the car on the
on-ramp. PHQ-9 9 (item 9 = 0). GAD-7 15 (was 16). Sleep 6 hours. No SI.
Quote: "I can feel it coming and I just pull over."
Assessment
Panic disorder, still moderate, with driving avoidance that costs her about
two hours of work a week. Today: interoceptive exposure (spinning in chair,
then standing) paired with cognitive restructuring of "I will pass out."
She completed both trials. SUDS 8 to 5. Affect shifted from tearful to
irritated-and-willing. Progress: small, specific, not yet generalized to
the on-ramp.
Plan
Homework: one on-ramp with partner in passenger seat, 10-minute sit if she
pulls over, no turning around. Next session: review SUDS log and add a
solo trial if today's homework holds. Coordinate with NP: no benzo PRN
started; she asked, I advised against standing PRN given exposure work.
Follow-up 1 week.Questions people ask
Do I have to use DAP? No. SOAP and BIRP can show the same thread. If your agency requires DAP, do not hide the intervention in Data. Reviewers skip to Assessment.
Can I bill 90837 if we spent 20 minutes on paperwork? No. Chart the psychotherapy minutes. Paperwork is not 90837.
