1. Physical Therapy Billing: A Complete Guide
Physical therapy (PT) plays a crucial role in rehabilitation and improving patients' quality of life.
However, the billing process for physical therapy services can be complex and challenging due
to evolving regulations, coding requirements, and insurance policies. Understanding the nuances
of Physical Therapy Billing is essential for maximizing reimbursements and ensuring
compliance.
In this comprehensive guide, we’ll break down the fundamentals of physical therapy billing,
including coding, documentation, common challenges, and best practices.
Understanding Physical Therapy Billing
Physical therapy billing involves submitting claims to insurance providers for services rendered
by physical therapists. It follows a process similar to other medical billing specialties, such as
Internal Medicine Billing and OBGYN Billing, but has unique coding requirements and
regulations.
Key Components of PT Billing
1. Evaluation & Documentation – Proper documentation of patient assessments and
treatment plans is crucial for accurate billing.

2. 2. CPT Codes – Current Procedural Terminology (CPT) codes are used to classify the
services provided.
3. Modifiers – These provide additional details about the services rendered and are crucial
for claims processing.
4. ICD-10 Codes – Used for diagnosis reporting to justify medical necessity.
5. Claim Submission – Claims must be submitted correctly to avoid denials or delays.
CPT Codes for Physical Therapy
Common CPT codes used in Physical Therapy Billing include:
 97110 – Therapeutic exercises
 97112 – Neuromuscular re-education
 97140 – Manual therapy techniques
 97530 – Therapeutic activities
 97535 – Self-care and home management training
Using the correct CPT codes ensures proper reimbursement for services provided.
The Role of Documentation
Accurate documentation is vital for ensuring claims are not denied. Key elements include:
 Initial Evaluation – A comprehensive assessment of the patient’s condition.
 Treatment Notes – Detailed records of each session, including progress and changes.
 Progress Reports – Updates on the patient’s improvement and continued need for
therapy.
 Discharge Summary – Final evaluation when therapy is completed.
Failure to maintain proper documentation can lead to claim denials or audits.
Common Challenges in Physical Therapy Billing
Physical therapy billing comes with its share of challenges, including:
1. Insurance Denials
Insurance companies may deny claims due to incorrect codes, missing modifiers, or lack of
medical necessity documentation.
2. Underpayments
Some insurers reimburse at lower rates, impacting revenue. Understanding payer contracts helps
ensure fair compensation.

3. 3. Compliance Issues
Regulatory compliance with HIPAA and Medicare guidelines is critical. Non-compliance can
result in penalties or claim rejections.
4. Prior Authorizations
Some insurance plans require prior authorization for PT services, adding an extra step in the
billing process.
5. Frequent Code Changes
Medical coding updates occur regularly. Staying informed about changes is essential to avoid
claim rejections.
Best Practices for Successful PT Billing
1. Verify Patient Eligibility
Before providing treatment, verify insurance coverage, copays, and deductibles to avoid payment
issues.
2. Use Correct Modifiers
Common modifiers in PT billing include:
 GP – Services delivered under an outpatient physical therapy plan.
 59 – Distinct procedural service.
 KX – Services exceed therapy cap but are medically necessary.
3. Submit Clean Claims
Ensure all claims are accurate and complete to prevent denials and delays. Double-check patient
details, codes, and modifiers before submission.
4. Appeal Denied Claims
If a claim is denied, review the reason, correct any errors, and submit an appeal promptly.
5. Keep Up with Regulatory Changes
Stay updated on CMS, Medicare, and private insurer policies to remain compliant and optimize
reimbursements.

4. Choosing the Right Billing Partner
Managing Physical Therapy Billing efficiently can be time-consuming. Partnering with a
reliable billing service like Crese Medical Billing can help streamline the process, reduce claim
denials, and improve revenue cycle management.
