Introduction to Physical Therapy (Physiotherapy) ICD 10 Codes
Physical therapy or Physiotherapy and rehabilitation practices address a wide range of musculoskeletal, neuromuscular, post-surgical, and orthopedic conditions. Whether treating patients with sports injuries, chronic joint pain, post-operative recovery needs, or neurological deficits, accurate ICD-10 coding (for physical therapy or physiotherapy) is essential for proper documentation, treatment planning, communication with referring physicians, and billing.
This guide offers a comprehensive list of ICD-10 codes used in physiotherapy or Physical Therapy to support outpatient rehabilitation clinics, inpatient therapy programs, orthopedic practices, and sports injury clinics. These codes help practitioners document the clinical rationale for treatment, create effective care plans, and receive reimbursement from insurers when applicable.
Using an all-in-one EHR platform like DocVilla enables physical therapists to integrate evaluation notes, SOAP documentation, ICD-10 lookup, CPT mapping, electronic prescribing, and appointment scheduling in one streamlined system. This supports both compliance and clinical efficiency.
Below is a categorized list of ICD-10 codes relevant to physical therapy.
