Musculoskeletal (Chapter 13)
- Laterality: Must specify Left, Right, or Bilateral.
- Episode of Care: Initial (A), Subsequent (D), Sequela (S).
- Specificity: “Low back pain” (M54.50) vs “Lumbar radiculopathy” (M54.16).
Neurological (Chapter 6)
- Stroke: Requires combination codes for side and dominance (e.g., I69.351).
- Peripheral Neuropathy: Must link to underlying cause (e.g., Diabetic G62.9 + E11.40).
Functional Limitations
- Medicare requires G-Codes and Severity Modifiers for outpatient therapy claims (PT/OT/SLP).
- Physicians do not bill G-codes on professional claims but must document the functional limitation to support medical necessity.
Common PM&R Diagnoses
- M54.50: Low back pain, unspecified.
- M25.561: Pain in right knee.
- G89.29: Other chronic pain.
- Z47.1: Aftercare following joint replacement surgery.
Unspecified Codes
Avoid “Unspecified” codes (ending in 9 or 0) whenever possible. They are high-risk for audits. Document laterality and specificity.
