In PT practice, using the ICD manual to select a code is considered what?

• A. A formal medical diagnosis
• B. Not a medical diagnosis and within PT scope
• C. Outside PT scope
• D. Diagnostic imaging ordering

Answer: (B)

Using the ICD manual to choose a code in PT is a coding task for billing and documentation, not a medical diagnosis. The therapist identifies the problem that therapy addresses and may record a therapeutic diagnosis or impression to guide treatment, but the formal medical diagnosis comes from a physician or other licensed clinician. ICD-10-CM codes help communicate the patient’s condition across the care team and support appropriate reimbursement, while staying within the PT scope by documenting impairment and functional limitations. If a specific medical diagnosis exists, the code should align with that; if not, the therapist can code for the presenting problem in a way that supports the plan of care, but this remains coding rather than declaring a medical diagnosis.
