Ask Your Data Anything
Why did my collections drop last week?
Collections dipped 8% due to 3 delayed Aetna payments (avg 42 days vs usual 18). All 3 are now posted — expect a $12,400 catch-up this week.
Which payer is causing the most denials?
UHC at 16.8% denial rate, primarily CO-16 (missing modifier). We've auto-added modifier 25 rules — denial rate trending to 4% this month.
We're Practice Perfect's Partner of Choice — the only billing company that can offer this level of integration on top of your EMR.
From millions of PT/OT/ST claims, we know exactly where practices lose money.
Generalist billers miss these every day. Our AI catches them before submission — not after the denial.

Scrub Engine — Sample Catches
⚠ 97110 × 3 units with 22 min → flagged 8-minute rule violation
⚠ Initial eval on existing episode → changed to 97164 re-eval
⚠ Manual therapy same region as 97112 → flagged for mod 59 review
Why Generalists Fail PT/OT/ST Practices
If your biller treats a re-evaluation like an initial eval, you get flagged. If they bill 3 units of therapeutic exercise on 22 documented minutes, you get downcoded.
8-Minute Rule Errors
Generalists don't validate units against documented time, leading to costly downcoding and audit risk.
Caught by 156 timing rules → <1% errors
Plan of Care Lapses
Generalists miss expired POCs and unsigned re-certifications — every claim after the lapse is denied.
100% POC tracking with auto-alerts
Eval Complexity Mismatches
Generalists default to low complexity and undercode — losing $40–60 per visit on every initial eval.

How does CBS + AI compare to a typical PT/OT/ST practice?
Across every revenue-cycle metric, a rehab-specialist team backed by AI outperforms the typical practice — faster billing, far fewer denials, higher clean-claim rates, and aged A/R that gets worked instead of written off. Here is the side-by-side.
| Metric | Typical PT/OT/ST Practice | CBS + AI |
|---|---|---|
| Time to bill | 3–5 days | 4 hours |
| Denial rate | 10–15% | 4.1% |
| Clean claim rate | 82% | 97% |
| AR > 90 days | 20–25% | 5.2% |
| Days in AR | 42–50 | 28 |
| Aged AR recovery | Written off | We go get it |
"Has your current biller ever shown you this?"
CBS has brought a level of competence to our billing that I have been trying to achieve since opening my clinic in 2007. Having them as part of our team has allowed me to concentrate on creating the best physical therapy experience possible for our patients and not worrying about the complicated intricacies of billing.

Frequently asked questions about therapy medical billing
Straight answers about PT, OT, and ST revenue cycle management: how rehab billing works, what it costs, and what changes when you switch to a specialty team.
Reviewed by the Clinical Billing Solutions RCM team · Last updated June 18, 2026
What is revenue cycle management (RCM) for a PT, OT, or ST clinic?
Revenue cycle management (RCM) is the end-to-end process a physical, occupational, or speech therapy clinic uses to get paid. It runs from insurance verification and charge capture through coding, claim submission, denial management, and final payment posting. Strong RCM can support a higher clean-claim rate and fewer days in accounts receivable (A/R).
How is PT, OT, and ST billing different from general medical billing?
Therapy billing runs on time-based CPT units, the Medicare 8-minute rule, plan-of-care and re-certification deadlines, and therapy-specific modifiers (GP, GO, GN, KX, 59). Generalist billers who do not apply these rules can lose revenue to downcoding and denials that specialty-trained billers are more likely to catch before submission.
What is the Medicare 8-minute rule and how does it cause billing errors?
The 8-minute rule is the Medicare standard for billing time-based therapy codes: a provider must furnish at least 8 minutes of a timed service to bill one 15-minute unit. Billing more units than the documented minutes support is a common cause of downcoding, denials, and audit risk.
Why do generalist billing companies struggle with rehab therapy claims?
Generalist billers cover dozens of specialties and rarely focus on therapy rules. They can miss 8-minute-rule unit math, expired plans of care, evaluation-complexity levels, and NCCI edits that require modifier 59. That often means more denials and lower reimbursement than a rehab-focused billing team would typically see.
How much does outsourced therapy billing cost?
Most outsourced rehab billing is priced as a percentage of collections, so your biller is paid when you collect. Clinical Billing Solutions reviews your current billing cost and works to offer a competitive rate. Because AI helps handle the claim volume, we aim to keep our pricing efficient for your practice.
What happens to our old A/R and outstanding claims when we switch to CBS?
During onboarding we review your aged accounts receivable, then work old and current claims in parallel. That includes re-working, resubmitting, and appealing eligible balances where appropriate, while we take over new claim scrubbing at go-live.
How does CBS integrate with the Practice Perfect EMR?
Clinical Billing Solutions is the exclusive Practice Perfect-approved RCM partner, so our workflow connects directly to your Practice Perfect data for real-time claim status and automated charge capture. That means no clunky exports or manual re-entry, and less friction between clinical documentation and billing.
Is our patient data secure with an outsourced billing partner?
Yes. As a medical billing company, Clinical Billing Solutions handles protected health information under HIPAA safeguards, and our US-based team works your claims domestically. Please note that our website forms are for general inquiries only. Never submit patient PHI through a contact form.
How quickly will we see results after going live with CBS?
Timelines vary by practice, payer mix, and the state of your existing claims. Our goal is to improve clean-claim rates and reduce denials over the first few billing cycles, and we begin reviewing aged A/R during onboarding so older claims are not left unaddressed.
