Medical Billing for Physical Therapy Practices

Physical therapy billing runs on details that are hard to keep perfect part-time: timed units and the 8-minute rule, KX modifier thresholds, visit authorizations, and plans of care that expire mid-treatment. The care is hands-on and the schedule is full — billing follow-up is nobody's full-time job, and A/R quietly grows.

Doctors One Solution handles the full revenue cycle for physical therapy practices — eligibility and authorizations up front, clean claims, and denials followed up every week.

Where physical therapy billing leaks money

  • Timed-unit errors. The 8-minute rule decides how many units a session earns, and small documentation or counting slips repeat across every visit, every week.
  • KX threshold surprises. Once a patient crosses the therapy threshold, claims need the KX modifier and documentation that supports medical necessity — applied consistently, not discovered at denial.
  • Authorization and plan-of-care lapses. Visits delivered after an authorization runs out, or under an expired plan of care, are services already rendered that may never be paid. We track both before they lapse.
  • Eligibility changes mid-episode. Benefits reset, plans change, and visit limits get consumed across a plan of care. Verifying at intake only isn't enough.

What we handle for physical therapy practices

  • Eligibility and benefits verification, including visit limits and authorization requirements
  • Authorization tracking and plan-of-care expiration monitoring
  • Claim scrubbing and submission — timed units and modifiers checked before payers see them
  • Denial management — worked, appealed, and tracked to resolution
  • Payment posting and ERA reconciliation
  • A/R follow-up on aging claims, plus monthly reporting on collections, denial trends, and days in A/R

FAQ

Do you only work with certain EHRs, or can you bill in ours? Any of them — we work with all major EHRs. Doctors One Solution is a Tebra RCM Partner and a partner of IMS by Meditab, but we're not limited to either: we bill inside whatever system your practice already uses, with no software switch or migration.

Do you handle authorizations? We track authorization status and plan-of-care expirations and flag them before visits are at risk; your front office keeps scheduling, we keep the billing clock.

What size practices do you work with? Independent practices from solo providers up to about ten — physical therapy is one of our core specialties.
