Physical Therapy Billing Services
Physical Therapy Billing Services That Get You Paid for Every Visit
Physical therapy billing is more complex than it looks: unit-based timed code documentation, modifier requirements for GP, KX, and CQ designations, therapy cap tracking, payer-specific credentialing rules, and functional limitation reporting all create constant denial risk. ProtoMed's certified PT billing specialists handle every claim accurately and completely. Fewer denials. Faster reimbursements. More revenue.

Why Choose Us
Stop Losing PT Revenue to Unit Errors, Modifier Mistakes, and Payer Denials
Physical therapy billing runs on timed units, and most revenue losses in PT happen not from outright claim denials but from systematic underbilling. A therapist who provides 60 minutes of timed services should bill 4 units, but an incorrect 8-minute rule application might result in 3. Multiply that error across 30 visits a day, 250 days a year, and the revenue loss is substantial. Add in the wrong modifier on a Medicare claim, missing the KX modifier when a patient is past the therapy threshold, and the claim is denied entirely.
ProtoMed's certified physical therapy billing team understands every dimension of PT revenue cycle management: the 8-minute rule, correct unit counting for concurrent timed services, GP modifier requirements for Medicare, CQ modifier rules for PTAs, KX threshold tracking, and the payer-specific documentation requirements that determine whether a claim is paid or denied. We submit clean claims, maximize your billable units, and follow up on every denial so your practice collects what it has earned.

Procedure-Specific Services
Specialized Billing for Every Physical Therapy Service
PT billing demands accurate unit counting, correct modifier application, and payer-specific documentation standards for every visit. ProtoMed's certified team handles every service type correctly, maximizing revenue on every claim.
Timed Code & Unit Calculation Billing
Physical therapy revenue lives in timed codes, and the 8-minute rule determines exactly how many units of each service can be billed based on the minutes spent. Incorrect unit calculation is the most common and most costly billing error in PT. We apply the 8-minute rule correctly for every visit, maximize billable units within payer-allowed totals, and ensure the time documentation in your notes matches the units billed on every claim.
Medicare & Therapy Cap Billing
Medicare PT billing requires the GP modifier on every claim, KX modifier when patients exceed the therapy cap, and functional limitation G-codes when required. Tracking each patient's therapy cap status, applying the KX modifier correctly, and ensuring documentation supports medical necessity beyond the cap are all essential to prevent high-value Medicare denials. We manage the complete Medicare PT billing cycle including cap tracking and exceptions management.
PTA Billing & CQ Modifier Compliance
When a physical therapist assistant provides services, the CQ modifier is required on all Medicare claims. When services are split between a PT and PTA in the same visit, specific modifier and billing rules apply. Incorrectly applied CQ modifiers result in Medicare denials that are entirely preventable. We accurately track PTA service delivery and apply CQ modifiers compliantly on every claim where a PTA is involved in patient care.
PT Evaluation & Complexity Level Billing
The 2019 CPT revision restructured PT evaluations into low, moderate, and high complexity levels. Each requires specific documentation elements to justify the complexity level billed. Billing a high complexity evaluation without the supporting MDM documentation is an audit risk. We ensure every PT evaluation is coded at the correct complexity level with the clinical documentation that supports it, capturing the full reimbursement value of your evaluation services.
Modality Billing (Timed & Untimed)
Physical therapy modalities, including electrical stimulation, ultrasound, traction, and hot/cold packs, each have distinct billing rules. Some are timed codes requiring 8-minute rule application; others are untimed flat-fee codes billed once per visit regardless of duration. Billing an untimed code as a timed code is an over-coding violation. We accurately distinguish timed from untimed modalities and apply the correct billing rules to every modality service provided.
Prior Authorization & Eligibility Management
Many commercial payers require prior authorization for physical therapy, and the number of approved visits varies by plan, diagnosis, and payer. A single authorization gap can mean an entire course of treatment goes unpaid. We verify patient eligibility and PT benefits before the first visit, obtain and track prior authorizations, and flag when authorization limits are approaching so your clinical team can request extensions before coverage lapses.
How It Works
How ProtoMed's Physical Therapy Billing Process Works
A structured four-step process that maximizes revenue on every visit, from the initial eligibility check and authorization through final payment posting on every claim.
Practice Audit & Revenue Gap Analysis
We review your current PT billing setup, identify revenue leaks from unit calculation errors, missing modifiers, unapplied KX thresholds, and unresolved denials, then securely access your existing PT software with zero disruption to your clinical schedule or patient flow.
Eligibility Verification & Prior Authorization
Before each new patient's first visit, we verify PT benefits, confirm authorized visit counts, identify payer-specific documentation requirements, and obtain prior authorizations where required. Catching eligibility and authorization gaps before the first treatment eliminates the most preventable source of PT claim denials.
Claim Coding, Scrubbing & Payer Submission
Our certified PT billers review every visit note, calculate timed units correctly under the 8-minute rule, apply the correct modifiers (GP, KX, CQ), and scrub each claim against payer-specific rules before submission. Claims are submitted electronically on time to Medicare, Medicaid, and all major commercial payers with the documentation needed for first-pass acceptance.
Denial Management, Payment Posting & Reporting
Every denied claim is investigated, corrected, and appealed with the clinical documentation required for reversal. Payments are posted accurately, and you receive clear monthly reports tracking your revenue per visit, denial patterns, payer reimbursement rates, and overall financial performance by provider and location.
