Quick Answer

How is physical therapy billing different?

Physical therapy is billed in timed units governed by the Medicare 8-minute rule, with strict plan-of-care, re-certification, and therapy-threshold (KX modifier) requirements. Miscounting units or missing documentation leads to downcoding and denials, so PT-specific billing expertise is critical.

Why It Matters

Physical therapy practices lose revenue to unit-counting errors

The 8-minute rule turns small mistakes into big write-offs.

Physical therapy reimbursement is uniquely tied to time. Timed CPT codes like therapeutic exercise (97110) and manual therapy (97140) are billed in 15-minute units under the Medicare 8-minute rule, while untimed codes like the PT evaluation are billed once per visit. Count units wrong and Medicare downcodes the claim, or denies it outright.

Layer on plan-of-care certification, progress-note requirements, therapy thresholds with KX modifiers, and payer-specific visit limits, and it is easy for busy clinics to lose thousands in preventable write-offs. MedTaskly's rehab-trained billers apply these rules precisely, keeping a 98% clean-claim rate and your cash flow healthy.

FAQ

Physical Therapy Billing Services — questions answered

What is the 8-minute rule in PT billing?
The Medicare 8-minute rule determines how many timed units you can bill based on total treatment minutes. You need at least 8 minutes of a timed service to bill one unit. Correct application prevents downcoding and denials.
Which CPT codes do physical therapists bill?
Common PT codes include 97161-97163 (PT evaluation), 97110 (therapeutic exercise), 97112 (neuromuscular re-education), 97140 (manual therapy), and 97530 (therapeutic activities). Timed codes must follow the 8-minute rule.
Why do PT claims get denied?
Top causes are incorrect timed-unit counts, missing or expired plan-of-care certification, exceeded visit limits, and missing KX modifiers at the therapy threshold. Specialized billing prevents these.
Do you bill for cash-based and in-network PT?
Yes. MedTaskly supports in-network insurance billing, out-of-network claims, and hybrid cash-based practices, with correct documentation for each model.
