Medicare’s 8-Minute Rule is a billing formula for PT, OT, and Speech Therapy to convert treatment time into reimbursable units. It ensures clinics bill accurately for timed services (like therapeutic exercises) while preventing overcharging.
Example in Action:
Physical Therapy Session
Total Time Minutes | Billable Units | Common CPT Codes |
8–22 | 1 | 97110 (PT exercise), 92507 (SLP) |
23–37 | 2 | 97140 (manual therapy), 92526 (ST) |
38–52 | 3 | 97530 (orthotic training) |
53–67 | 4 | 97763 (prosthetic training) |
