Documentation Best Practices

Documentation Checklist
  • Physical therapy initial evaluation documentation
  • ICD-10 diagnosis codes, CPT billing codes
  • Document patient medical history, pain levels
  • Treatment plan, goals, objective measurements
  • Progress notes, reassessments, discharge summary

Coding and Audit Risks

Common Risks
  • Unspecified Diagnosis

    Using unspecified physical therapy diagnosis codes when a more specific code is available leads to inaccurate reimbursement and data.

  • Medical Necessity

    Lack of documentation supporting the medical necessity of physical therapy services can trigger denials and compliance issues.

  • Incorrect Modifier Use

    Applying incorrect modifiers to physical therapy CPT codes can result in claim rejection and potential overpayments or underpayments.

Mitigation Tips

Best Practices
  • ICD-10 code accuracy for PT diagnosis: Verify primary reason for visit.
  • Specificity in PT documentation improves medical coding & billing compliance.
  • Document functional limitations & justify medical necessity for PT interventions.
  • Use standardized PT terminology for CDI & consistent patient care.
  • Regularly audit PT documentation for coding accuracy & compliance updates.

Clinical Decision Support

Checklist
  • Verify ICD-10 diagnosis code matches patient's condition
  • Confirm PT plan aligns with diagnosis and functional limitations
  • Document patient's progress towards goals in each session
  • Check for contraindications and precautions before each treatment
  • Ensure accurate CPT codes for billing and reimbursement
