Good occupational therapy documentation does three things at once: it tells the story of skilled care, it satisfies the people who pay for that care, and it protects your license if anyone ever asks "why did you do that?" Get any one of those wrong and the other two start to crumble.
This guide is the single reference you need to write OT notes that hold up under a Medicare audit, a state board complaint, or a peer-review request. We will walk you through what AOTA, CMS, and state licensing boards actually require, show you the words that signal skilled care to a reviewer, and give you side-by-side examples of a weak note rewritten into a defensible one.
AOTA's Guidelines for Documentation of Occupational Therapy (2018) frames the purpose plainly: documentation reflects the nature of services provided, shows the clinical reasoning of the practitioner, and provides enough information to ensure services are delivered safely and effectively.
That sentence is doing a lot of work. Pull it apart and you have four audiences your note has to satisfy at the same time:
Every choice in the rest of this guide flows from those four readers. If a sentence in your note does not help at least one of them, it is filler.
OT documentation lives at the intersection of three rule sets. You need to know which one is talking when.
AOTA's Guidelines for Documentation of Occupational Therapy were published in the American Journal of Occupational Therapy, Volume 72, Supplement 2 (DOI 10.5014/ajot.2018.72S203). They are not law, but they are the profession's consensus on what an occupational therapy practitioner should be writing. State boards and payers frequently incorporate them by reference.
AOTA identifies a small set of documentation types that map to the OT process: the occupational profile, the evaluation report, the intervention plan, contact and progress notes during the episode of care, and a discharge or discontinuation report. The specific wording of the 2018 standard sits behind an AOTA member paywall, so if you are writing internal policies, pull the AJOT article and quote it directly.
For outpatient occupational therapy, the rules that matter most are in the Medicare Benefit Policy Manual, Chapter 15, sections 220 and 230. Commercial payers and Medicaid programs frequently model their requirements on these, so even if you do not see a single Medicare patient, the CMS framework is the safest baseline.
The numbers you have to commit to memory:
| Requirement | Rule | CMS source |
|---|---|---|
| Plan of care certification | Obtain physician/NPP certification within 30 calendar days of the initial therapy treatment | Ch. 15 §220.1 |
| Recertification | At least every 90 calendar days from the date of the initial treatment, or for the duration of the plan of care, whichever is less | Ch. 15 §220.1 |
| Progress reports | At minimum every 10 treatment days OR once during each certification interval, whichever is less (10 treatment days almost always controls) | Ch. 15 §220.3 |
| Treatment notes | Required for every treatment day and every therapy service | Ch. 15 §220.3 |
| Discharge note | Required at the end of each episode of outpatient treatment; covers the period from the last progress report to discharge | Ch. 15 §220.3 |
The other 2026 number every outpatient OT needs to know is the KX modifier threshold. For calendar year 2026, the threshold above which claims must include the KX modifier and the medical record must justify continued medical necessity is $2,480 for occupational therapy services (PT and SLP share a separate $2,480 combined threshold). The targeted medical-review threshold sits at $3,000. Source: CMS CY 2026 Medicare Physician Fee Schedule Final Rule Summary, MM14315.
If your patient is approaching the $2,480 KX threshold, your next progress note is where you earn the right to keep treating. Skilled-care language in that note is the difference between paid claims and denied ones.
CMS sets the rhythm of documentation. Your state board sets a different layer: who can sign, how fast you must sign, how long you keep the chart, and what counts as a complete record. The rules vary, so confirm yours.
Texas is a useful example because the rule is short and direct. Under the Texas Board of Occupational Therapy Examiners' rules at §372.1(g) (June 2025 edition), every client record must include the medical referral if required, the initial evaluation, the plan of care with goals and updates, documentation of each intervention session, progress notes and any re-evaluations, related patient documents, and the discharge documentation. An OTA's intervention note must include the name of an OT who is readily available to answer questions at the time of service.
California requires that records of continuing-competency activities be kept for four years following the renewal period (16 CCR §4162). Patient-record retention itself is governed by California medical-records statutes, not the OT board.
The practical rule: do not assume your state's requirements match Texas, California, or any other state you have practiced in before. Read your own board's rules, and re-read them after every renewal cycle.
HIPAA does not set a federal retention period for medical records. The rule at 45 CFR §164.530(j)(2) requires a covered entity to retain HIPAA-required documentation (policies, procedures, Notices of Privacy Practices, authorizations, accountings of disclosure) for six years from creation or the date it was last in effect, whichever is later. HHS confirms this distinction in FAQ #580: medical records themselves are governed by state law and CMS Conditions of Participation, not HIPAA.
If you have ever heard "HIPAA says keep records for six years," you have heard half of the rule. The right framing: "HIPAA requires six years for our policies and authorizations. The chart itself follows the state retention rule, which is usually longer."
The SOAP structure (Subjective, Objective, Assessment, Plan) was introduced by Dr. Lawrence L. Weed as part of the Problem-Oriented Medical Record in his two-part article "Medical Records That Guide and Teach," published in the New England Journal of Medicine on March 14 and 21, 1968 (278:593-600; 278:652-657). It has been the dominant note format in rehabilitation for nearly sixty years.
SOAP is not the only option. The variants you will encounter:
Pick the format your setting, your payer, and your EHR template support. Then be consistent. A reviewer who has to hunt for required elements across three formats in the same chart is a reviewer who will deny your claim.
The skeleton below works for outpatient OT in adult rehab, pediatrics, and mental health. The substance of each section changes by setting; the structure does not.
The patient's report in their own words, plus relevant caregiver report. Capture function, not just feelings.
Do:
Avoid:
What you measured, what you observed, and what intervention you provided. This is where most denials are won or lost, because it is where skilled-care language has to appear.
Required elements per CMS Ch. 15 §220.3 for outpatient treatment notes:
Do:
Avoid:
Your clinical reasoning. This is the section that says "a skilled occupational therapy practitioner was here today, and here is why that mattered." Reviewers read this paragraph hardest.
Do:
Avoid:
Next session's focus, frequency and duration of continued care, and any changes to the plan of care.
Do:
Avoid:
Medicare auditors do not read your note looking for proof you provided service. They read it looking for proof that a therapist was required. CMS Manual Ch. 15 §220.2 lays out the medical-necessity test: services must be of a complexity that they can be safely and effectively performed only by a therapist or under a therapist's supervision, and they must be reasonable in amount, frequency, and duration.
The words below signal "skilled" to a reviewer. Use them when they accurately describe what you did, and stop using them when they do not.
| Skilled language | What it signals |
|---|---|
| "Skilled instruction in..." | You taught a technique that requires a therapist's training |
| "Manual cues for..." | You provided hands-on facilitation that an unskilled caregiver could not |
| "Graded the activity to..." | You modified task demand based on real-time clinical judgment |
| "Trained patient/caregiver in..." | You transferred a skill to someone outside the clinic |
| "Assessed/re-assessed..." | You took or interpreted an objective measure |
| "Modified the home program to address..." | You used clinical reasoning to change the plan |
| "Required min/mod/max-A for..." | You provided graded physical assistance |
| "Cued for safety with..." | You intervened on a safety issue requiring clinical judgment |
Words that do not signal skilled care: monitored, observed, encouraged, supervised exercises, helped, assisted. They can appear in your note, but they cannot be the whole story.
One important nuance: the Jimmo v. Sebelius settlement (2013) clarified that Medicare cannot deny services solely because a patient has "plateaued" or lacks improvement potential. If maintaining function or slowing decline requires the skills of a therapist, the service is covered. The documentation has to show that. Phrases like "skilled instruction required to safely maintain..." or "patient at risk of functional decline without skilled intervention to..." support a Jimmo-compliant maintenance program.
The single fastest way to improve your documentation is to read a real note next to a corrected version. Below is an outpatient OT note for a 64-year-old female, six weeks post-CVA with right hemiparesis, working on UE function for ADLs.
S: Pt feels good. Reports she did her home exercises.
O: Pt seen for 45 min. Worked on UE strengthening and ADLs. PROM/AROM RUE shoulder. TheraBand exercises. Practiced dressing. Pt tolerated treatment well.
A: Pt is progressing. Continue POC.
P: Continue plan.
What is wrong here: nothing in the objective section identifies what a therapist did that an unskilled aide could not. No measures. No grading. No clinical reasoning. The assessment and plan are not assessments or plans. A Medicare reviewer would deny this claim and recover prior payments going back to the start of the episode.
S: Pt reports completing home program 5 of 7 days this week; missed two days due to fatigue. States: "I can get my shirt on now without help, but I still can't manage the buttons." Denies pain. No falls or new symptoms since last visit.
O: Pt seen 1:1 for 45 min skilled OT in outpatient clinic.
- UE re-assessment: RUE shoulder AROM flexion 0-115 deg (up from 95 deg on 11/4), abduction 0-95 deg (from 80 deg). Right grip dynamometry 22 lbs (from 18 lbs); left 58 lbs. Right 9-Hole Peg 48 sec (from 62 sec). Left UE WFL.
- Skilled instruction in scapular stabilization with PNF D2 flexion patterns; manual cues provided to inhibit upper trapezius substitution. Pt progressed from min-A to CGA over 3 sets of 10 reps.
- Graded buttoning task: began with 1-inch buttons on dressing board, advanced to 0.5-inch buttons on her own blouse. Required mod-A and verbal cues for thumb opposition on first 2 buttons; reduced to min-A and intermittent visual cues by button 5. Skilled instruction in tenodesis-grasp compensation for residual thumb weakness.
- Caregiver training (husband present): trained in technique for safe stand-pivot transfer with hemi-walker, emphasis on right-foot clearance to prevent recurrent toe-drag. Husband demonstrated independently after 2 reps.
A: Pt is progressing toward LTG of independent UD dressing within 8 weeks; current performance places her at the 6-week interim goal of mod-I with adaptive technique. AROM gains in RUE shoulder are clinically significant and correlate with improved functional reach during dressing. Continued skilled OT remains medically necessary to address residual fine-motor deficits limiting fastener management and to progress caregiver training as motor recovery continues. Pt approaching $2,480 KX threshold; medical necessity documented above supports continued treatment.
P: Continue 2x/week for 4 weeks. Next session: progress to standing dressing tasks at sink (incorporates DB simulation), introduce timed buttoning baseline for outcome tracking, advance home program to include 1-lb cuff weight for shoulder AROM. Re-screen 9-Hole Peg and grip dynamometry at 4-week interval.

Same patient. Same 45 minutes. Two completely different stories to a reviewer. The rewrite documents objective change, skilled intervention, clinical reasoning, and medical necessity. It survives an audit. The weak version triggers one.
The SOAP skeleton stays the same. The emphasis shifts.
Short stays, fast turnover. Emphasize medical stability, transfer training, and discharge recommendations. Document precautions every visit (sternal, weight-bearing, hip, swallow). The discharge note often functions as the handoff to the next level of care.
Medicare requires that the patient need and tolerate 3 hours of intensive therapy per day, 5 days a week (or 15 hours over 7 consecutive days). Document time precisely, document tolerance with measures, document interdisciplinary coordination.
Documentation drives Patient-Driven Payment Model (PDPM) classification. Capture function on Section GG of the MDS accurately and consistently between OT, PT, and nursing. SOAPIE or SOAPIER is common.
Document the homebound criteria every visit. Address the home environment, caregiver capacity, and safety. OASIS scoring must be supported by your therapy notes; mismatched scores are a top audit trigger.
The CMS rules above apply most directly here. Track the KX threshold, document medical necessity at every visit, and lean hard on objective re-measurement to show progress (or to justify a change in plan when there is none).
Tie every intervention to a functional goal that the family cares about. Document parent education and home-program transfer. In early intervention, document the family-centered model: who was present, what coaching you provided, what the family will practice.
Document IEP goals, related-services minutes delivered, and progress toward each goal. School OT notes are educational records under FERPA and may also be medical records if billed to Medicaid; check your district's policy.
DAP format is common. Document occupation-based interventions (vs. talk-therapy proxies), risk assessment when relevant, and coordination with the broader treatment team. Avoid clinical language that veers into psychotherapy unless it is within your scope and credentials.
Telehealth has its own documentation requirements layered on top of everything above.
For electronic records: EHR auto-population is convenient and dangerous. The same copy-paste that saves you ten minutes is the pattern reviewers flag first. Edit every section every visit. If your EHR pre-fills the assessment, treat that as a starting prompt, not the final note.
AI scribes for therapy notes are now widely available. They can save real time. They can also fabricate findings, miss required elements, and import language that does not match what you did. A few rules of thumb for using them safely:
Over years of audited charts, the same handful of patterns drive the majority of denials and clawbacks:
The tension every OT lives with: documentation has to be thorough, and you have eight more patients waiting. A few habits that buy you minutes without sacrificing the note:
Tape this above your workstation. If a note has all of these, it is ready to sign.
If you read this far and want to actually change your documentation, three concrete moves:
Documentation is not the part of OT anyone went to school dreaming about. It is the part of OT that determines whether you get to keep doing the work you went to school for. Treat it that way.
