Therapy cap tracking & prior authorization management
Credex Healthcare runs a dedicated physical therapy billing process that reviews each session note before charge entry. Our PT billing specialists confirm that the evaluation code selected matches the documented complexity level based on the patient’s physical profile, the number of performance areas assessed, and the clinical decision-making documented in the evaluation report. For treatment visits, we verify that time-based procedure codes are supported by the exact number of minutes documented in the session note and that the GP modifier is applied correctly on all Medicare outpatient therapy claims. Physical therapy billing errors and fixes are expensive at scale a time documentation error on a 97530 code that repeats across 200 sessions month ly compounds into significant revenue loss before anyone notices.
Our physical therapy billing services in the USA cover the following:
Claims go out with verified CPT codes, correct evaluation complexity levels, time-based unit counts supported by session documentation, and GP modifier applied to all Medicare outpatient therapy claims. Our team tracks adjudication in real time and follows up before timely filing windows close.
We manage provider enrollment for physical therapists and PTAs with Medicare, Medicaid, and commercial carriers, including supervision documentation requirements for PTA billing under Medicare's differential payment rules.
Denied PT claims are reviewed within 48 hours. Whether the rejection came from a time documentation gap, an incorrect evaluation level selection, a missing prior authorization, or a therapy cap compliance error, our team corrects it and resubmits with the clinical documentation that specific payer requires.
Our certified coders audit session notes against physical therapy CPT codes 97110, 97112, 97140, 97530, confirming that evaluation complexity, time documentation, and therapeutic goal documentation support each code and unit count billed.
Commercial payers and specific Medicaid programs require prior authorization for physical therapy treatment plans beyond an initial evaluation period. We initiate and track authorizations before treatment begins, so no session is denied for missing payer approval on an active treatment plan.
End-to-end revenue optimization covers eligibility verification, therapy plan documentation review, time-based charge capture, Medicare therapy cap and KX modifier tracking, payment posting, and monthly reporting so practice administrators have accurate collections data by payer each billing cycle.
As a dedicated physical therapy billing company in the USA, Credex Healthcare tracks Medicare guidelines for physical therapy billing as CMS updates them, monitors commercial payer prior authorization requirement changes for PT treatment plans, and maintains current outpatient therapy billing compliance standards for the full physical therapy CPT code set. Medicare coverage for physical therapy services requires that each session be documented as medically necessary, that the patient is making measurable progress toward functional goals, and that PTA-provided services are billed with the CQ modifier and reimbursed at 85% of the PT rate. Applying those rules incorrectly across a high-volume outpatient therapy practice is a compliance exposure that accumulates quickly.
Medicare covers physical therapy services under Part B for medically necessary treatment with documentation of functional limitations. We manage Medicare PT billing with correct GP modifier application, KX modifier for therapy cap exceptions, CQ modifier for PTA-provided services, and annual therapy cap threshold tracking for every Medicare patient on census.
Medicaid physical therapy coverage and prior authorization requirements vary by state and by patient population. Pediatric PT through school-based programs, early intervention, and Medicaid waiver programs each carry different billing rules. Our team maintains state-specific Medicaid PT billing standards and applies them correctly to every claim.
Pediatric physical therapy billing covers outpatient clinic, school-based, and early intervention settings, each with different code sets, payer rules, and documentation standards. School-based PT may bill Medicaid under the school billing pathway. We manage pediatric PT billing across all service settings.
Physical therapy in skilled nursing facilities is bundled into the PDPM rate under Medicare Part A. For home health PT, billing follows the OASIS-based home health episode payment system. We manage PT billing in each care setting under the correct payment methodology rather than applying a standard outpatient billing approach.
Physical therapy claims fail for specific, preventable reasons: evaluation codes billed at the wrong complexity level, time units not matching the documented minutes in the session note, GP modifier missing on Medicare outpatient claims, KX modifier not applied when the therapy cap is exceeded, and prior authorizations not in place before treatment begins. Credex Healthcare reviews all of those before any claim goes out.
Every PT and PTA in your practice is verified for active enrollment with each payer, correct therapy specialty taxonomy, and Medicare Part B billing eligibility before claims are submitted under their provider number.
We audit PT evaluation reports against CPT 97110 (timed therapeutic exercises), 97112 (neuromuscular reeducation), 97140 (manual therapy techniques), and 97530 (therapeutic activities), confirming that the documented physical profile, number of performance areas assessed, and clinical decision-making complexity match the level billed per the AMA code descriptor requirements.
CPT 97530 and 97535 are time-based codes billed in 15-minute units. Each unit requires at least 8 minutes of direct one-on-one treatment time, as documented in the session notes. We verify that the number of units billed is supported by the documented treatment time for each procedure code on every claim.
Medicare outpatient PT claims require the GP modifier on every line. The KX modifier is added when the annual therapy cap threshold is reached to confirm medical necessity supports continued treatment. The CQ modifier identifies PTA-provided services. We track all three for every Medicare patient and apply them correctly at each billing point.
Prior authorization for physical therapy services is tracked by patients and payers. Commercial payers that require PA for treatment plans beyond the evaluation receive authorization requests before the first treatment session begins. Authorization renewals are tracked against the approved visit count.
Accounts Receivable Follow-Up
PT AR is reviewed weekly. Unpaid claims are followed up on before the timely filing limits close. Therapy cap denial appeals and time documentation disputes are escalated with the session note and Medicare therapy billing policy documentation that supports the original claim.
Physical therapy practices lose revenue through billing errors that recur from session to session without anyone catching them. The units for CPT code 97110 do not match the 8-minute rule that corresponds to the total treatment time. CPT code 97112 was correctly uploaded, but the claim was still denied due to unspecified treatment time. GP modifier is missing from a subset of Medicare claims because the billing template was not set up to apply it automatically. Credex Healthcare’s physical therapy billing process catches all three at the charge-entry stage before they compound over a month of visits.
End-to-end physical therapy insurance billing from session note review and evaluation level verification through time-based unit calculation and electronic submission to Medicare, Medicaid, and commercial payers for every PT encounter.
Our physical therapy billing specialists apply the correct CPT codes, evaluation complexity levels, time-based units, and required modifiers for every encounter type and payer, cutting the denials from therapy billing documentation requirement errors.
Prior Authorization Management
Prior authorization for therapy services is tracked from initial request through approval and linked to the treatment plan. Renewal requests are initiated before the approved visit count is reached, so no session is billed against an expired or missing authorization.
Denial management for physical therapy claims covers evaluation-level disputes, time-documentation corrections, Medicare modifier errors, and therapy cap compliance appeals. Each appeal is built around the prescribed session note format and payer or Medicare policy that reverses the denial.
Provider application management covers PT enrollment, PTA billing setup under Medicare's CQ modifier and 85% payment rules, group NPI configuration, and ongoing recredentialing so your practice bills without interruption as staff changes or payer agreements renew.
Monthly reports cover collections by provider and payer, evaluation code distribution, time-based unit accuracy, therapy cap status by Medicare patient, denial trends by CPT code, and physical therapy billing turnaround time, so practice owners have the data to manage the business.

“We had a recurring problem with our PT evaluation coding. Our therapists were consistently selecting 97110 for therapeutic exercises when a significant portion of our evaluations were actually therapeutic activities under the AMA criteria. Credex reviewed the evaluation documentation against the code descriptors, identified that about 35% of our evaluations were erroneously coded, and corrected the selection criteria in our intake workflow. The compliance fix mattered as much as the revenue correction; we were carrying real audit risk and did not know it.”
Practice Manager

“Pediatric PT billing across school-based, outpatient, and early intervention settings is complicated by different payer rules for each setting. Our billing team was applying outpatient billing rules to school-based claims, and the Medicaid denials were constant. Credex separated the billing by setting type, applied the correct Medicaid school billing pathway for school-based claims, and our pediatric Medicaid denial rate dropped from 22% to under 5% in the first two months.”
Revenue Cycle Director
Job
“Our PT department was missing the KX modifier on Medicare claims after patients hit the therapy cap threshold. The billing system was not set up to flag when the annual cap was approaching, so therapists kept treating and billing without the modifier, resulting in denials that we then had to appeal one by one. Credex implemented therapy cap tracking per-patient and built the KX modifier trigger into the billing workflow, and therapy cap denials were prevented. That alone freed up significant AR that had been stuck in appeal.”
PTD

“Neuromuscular therapy billing involves specific CPT codes for therapeutic exercise, manual therapy, and reeducation that most billing companies lump together incorrectly. Credex understood the neuromuscular therapy code set, applied the correct codes for each intervention, and verified that the time documentation in the session notes supported the units billed. My denial rate on these therapy claims went from 17% to under 4%, and the collections per visit went up because we stopped underbilling the codes.”
CFO
Diallo
“Running PT billing across 7 locations with a mix of Medicare, Medicaid, and commercial payers meant four different authorization-tracking systems and no consistent modifier compliance across sites. Credex standardized the billing workflow, set up therapy cap tracking for every Medicare patient across all locations, and built a monthly report that shows time-based unit accuracy and denial rates by site. The consistency across locations made a real difference in both compliance and monthly collections.”
Practice Assessment
We review your current PT billing process and check things like the accuracy of the codes you choose, how you record time-based units, Medicare modifier compliance, therapy cap tracking status, prior authorization gaps, AR aging by payer, and denial history by CPT code. This shows exactly where the money isn't coming in.
Credentialing & Payer Enrollment
Every PT and PTA is checked to ensure they are currently enrolled with all payers, using the right treatment taxonomy, and set up their Medicare CQ modifier billing. Before new claims are submitted, any gaps in service application management are filled.
Compliance & Authorization Setup
We look at how you keep track of your Medicare therapy cap, make a calendar with per-patient cap thresholds, list all the insurance companies that need prior permission for PT treatment plans, and set up a tracking system to make sure that no session is charged against an authorization that is missing or has ended.
Clean Claim Submission
Our PT billing experts go over every session note, make sure the level of difficulty of the evaluations matches the number of minutes recorded, make sure the right GP, KX, and CQ factors are used, and send bills online to Medicare, Medicaid, and private insurers for every visit.
Denial Management & Follow-Up
As a claim moves through the process, it is tracked. Within 48 hours, denials are looked over again. There is a specific way to handle evaluation complexity disputes, time documentation changes, Medicare modifier mistakes, and prior authorization appeals. This is because they are all based on the session paperwork and the payer or Medicare treatment billing policy.
Reporting & Ongoing Optimization
The monthly reports show how much money was collected by the provider and the customer, the distribution of evaluation codes, the time-based unit accuracy rate, the state of treatment cap compliance, rejection trends by CPT code, the time it takes to bill for physical therapy, and how old the accounts receivable are. At the session-note level, documentation trends that lead to repeated refusal are fixed.
Pathology lab billing carries risks that general billing companies routinely miss: incorrect specifications for chemistry panels, LCD-specific diagnosis restrictions by MAC region, CLIA number mismatches, and panel unbundling rules that differ by payer. Credex Healthcare focuses on laboratory revenue cycle management specifically because these details require a billing team that works on pathology lab claims every day and knows where the compliance risks sit.
It is our job to handle requests for physical therapy. We understand how Medicare and AMA determine the three evaluation complexity levels, how time-based unit rules work for 97110 and 97112, how therapy cap thresholds trigger the KX modifier, and where physical therapy billing mistakes most often occur in session documentation and charge-capture workflows.
There is one physical therapy billing expert who works only for your practice. This person knows all your patients, your payer panel, your treatment cap status, and the trends of claims that keep getting denied. Problems are taken care of by an expert who knows PT bills and professional matters.
In monthly reports that show the practice's actual financial and compliance situation, practice owners can see how much is collected by provider and payer, how evaluation codes are distributed, how accurate time-based units are, how Medicare patients' therapy caps are doing, how often claims are denied by CPT code, and how long it takes to bill for physical therapy.
Full HIPAA compliance procedures shield all therapy records, evaluation reports, and session notes for patients that are handled during the payment process. Every system that handles claims for your business follows strict security rules and allows only certain people to access it.
Physical therapy practices lose revenue through billing patterns that repeat every session without surfacing as obvious problems. Evaluation codes are billed one level higher than the documentation supports. The GP modifier is missing from a subset of Medicare claims because no one audited the billing template. These are workflow problems that compound across hundreds of visits per month before they show up in the AR.
Credex Healthcare starts with a free review of your current PT billing: evaluation code accuracy, time-based unit documentation review, Medicare modifier compliance check, therapy cap tracking status, prior authorization gaps, and AR aging by payer. No commitment required to get that review. We identify the recoverable revenue and the specific workflow corrections that stop those losses from repeating.
It is the job of physical therapists and physical therapy assistants (PTAs) to send bills for PT evaluation and treatment services to Medicare, Medicaid, and private payers. This is called “billing.” CPT codes are assigned to each session based on the type of services offered and the length of time they last. For example, initial exams are given evaluation codes at one of three difficulty levels, and treatment sessions are given time-based procedure codes that are paid in 15-minute increments. CMS’s therapy billing guidelines make sure that outpatient therapy billing is done correctly for Medicare. These guidelines say that each session must be medically necessary and show measured progress toward functional goals. They also say that functional limitations must be documented.
Evaluation codes and time-based treatment process numbers are used to bill for physical therapy. At a low level of difficulty, CPT 97161 is the physical therapy exam. CPT 97162 is an exam of middling difficulty. CPT 97163 is an exam with a lot of moving parts. The amount of difficulty is based on the patient’s job, the number of performance areas that were tested, and the clinical decisions that were made during the evaluation. Therapeutic tasks involving direct patient interaction for effective success are covered by CPT 97530. Self-care and home management training for tasks of daily living and reintegrating back into the community are covered by CPT 97535.
Yes. Medicare Part B covers private physical therapy treatments that are medically necessary and are given by a trained PT or PTA. For coverage to apply, the patient’s health must be expected to improve, useful goals must be written down and measured, and success must be recorded by the therapist in each session of note. Medicare has an annual therapy cap that limits how much it will pay for PT. There is an exception process called the KX modifier that can be used when medically necessary treatment continues past the cap.
When evidence backs up the time units billed and necessary factors are applied properly, Medicare processes clean electronic PT claims in 14 to 30 days. When prior permission is on file and session notes to back up the codes provided, commercial payers usually pay within 30 days. When Medicaid applications are due varies by state, but they are usually 30 to 60 days. All three are taken care of by Credex Healthcare’s session note review and modifier compliance tracking before claims are submitted. This keeps most PT claims within the normal physical therapy billing timeline.
