Physical Therapy Billing Services

Physical Therapy Billing Services; Get Every Unit Right the First Time

Our physical therapy billing services are built specifically around the complexity of In timed units, not just visits, so your practice gets paid accurately and your therapists stay focused on patient rehabilitation instead of paperwork.

Built for Every Kind of Physical Therapy Practice

Independent PT Clinics

A single denied claim carries outsized weight for a small practice. We manage the full billing cycle so an independent clinic doesn't need in-house billing expertise to compete with larger groups.

Multi-Location PT Practices

More locations means more variation across therapists' documentation habits. We standardize coding, modifier use, and threshold tracking across every location.

Outpatient PT Within Larger Medical Groups

When physical therapy operates inside a larger orthopedic or multi-specialty group, billing needs to account for shared referral patterns. We coordinate accordingly instead of treating PT in isolation.

A Team That Knows Your Practice

You're assigned a dedicated billing team trained specifically on physical therapy coding and time-based billing — not a rotating queue of generalist billers.

Claims Built Right the First Time

Every claim goes out with correct units, modifiers, and supporting documentation attached, so it doesn't come back.

Total Visibility Into Your Billing

You see exactly what's been billed, what's been paid, and what's still outstanding — no black box.

Active Follow-Up on Every Aging Claim

Every claim on your A/R gets worked every month — not just the easy ones.

Denials Fought, Not Just Filed

Underpaid and wrongly denied claims get appealed with documentation to back them up, not resubmitted and hoped for.

Patient Balances Handled With Care

We manage patient statements, answer billing questions, and reconcile accounts once insurance pays clearly and without confusion.

Technology That Fits Your Workflow

We work inside the EHR and practice management system your clinic already uses, or bill directly from it if that's easier for your staff.

Credentialing Kept Current

Payer credentialing and contracting stay up to date, so a lapsed enrollment never holds up a claim.

Regular Check-Ins, Real Data

We meet with you on a regular schedule to walk through your actual billing data, not just send a report and disappear.

Coding Built Specifically for Physical Therapy

Physical therapy billing depends on getting procedure coding, units, and modifiers right — not just submitting a claim and hoping. Here's what that looks like in practice:

PT-Trained Coding Specialists

Our billing team works specifically with physical therapy CPT codes, modifiers, and unit calculations to reduce denials and compliance risk.

Accurate Modifier Application

Modifiers like GP, CQ, and KX are applied correctly and consistently, so claims meet payer requirements instead of getting flagged for missing or misused modifiers.

Ongoing Regulatory Training

Our coders stay current on physical therapy billing guidelines through continuous training, keeping every claim audit-ready.

Documentation Support That Holds Up

We provide clear guidance on what each claim needs documented, so it accurately reflects the treatment provided and its medical necessity.

The 8-Minute Rule, Explained Correctly

Medicare’s 8-minute rule determines how many units a therapy session earns, and it trips up more claims than any other single rule in physical therapy billing. To bill one unit of a timed code, a therapist must provide at least 8 minutes of that specific service. Total timed minutes for the day are then combined to determine total billable units: 8–22 minutes equals 1 unit, 23–37 equals 2, 38–52 equals 3, and so on.

Two details trip up practices that don’t specialize in PT. First, not every code is timed—evaluations, re-evaluations, and some modalities are billed as a single unit regardless of time spent, and mixing timed and untimed logic on the same claim is a common, avoidable error. Second, Medicare’s 8-minute rule isn’t universal—some commercial payers use the American Medical Association’s “Rule of Eights” instead, which can produce a different unit count from the same session. We calculate units against the correct methodology for each payer, not a one-size-fits-all default.

How much do physical therapy billing services cost?

Most physical therapy billing companies charge a percentage of collections, typically 4–8%, depending on claim volume and scope of service. Ask for a quote based on your actual visit volume and payer mix.

What is the 8-minute rule?

The Medicare methodology for converting timed treatment minutes into billable units is 8 to 22 minutes equals one unit, 23 to 37 equals two, and so on. Some commercial payers use a different calculation (the AMA’s “Rule of Eights”), which is a common source of confusion when applied universally.

What's the difference between timed and untimed PT codes?

Timed codes—therapeutic exercise, manual therapy, and neuromuscular reeducation—are billed in units based on minutes delivered. Untimed codes—evaluations and some modalities—are billed as a single unit regardless of time spent.

How can I reduce claim denials in my physical therapy practice?

The recurring causes are unit-calculation errors, a missing or incorrect GP modifier, and documentation that doesn’t clearly support the units billed. Catching these before submission is what actually reduces a denial rate.

Should I outsource my physical therapy billing?

It tends to make sense once unit calculation, modifier accuracy, or credentialing starts consuming more staff time than your practice can absorb.

What CPT codes come up most often in physical therapy billing?

Common codes include 97161–97163 (evaluation), 97164 (re-evaluation), 97110 (therapeutic exercise), 97112 (neuromuscular reeducation), 97140 (manual therapy), and 97530 (therapeutic activities). Confirm current-year codes with your coding team before publishing.

How long does switching billing companies take?

Most transitions run 2–4 weeks: system access, staff onboarding, and a review of open claims—run alongside your existing process so claims keep moving.
