M62.48 captures muscle contracture occurring at a body site that does not map to any of the specifically enumerated locations in the M62.4 subcategory — such as the trunk, cervical musculature, or pelvic girdle muscles.

Documentation tips

What should appear in the chart to support M62.48.

• Name the specific muscle or muscle group affected (e.g., 'right paraspinal contracture at L1–L3,' 'cervical scalene contracture') — 'muscle contracture, other site' without a named structure gives auditors nothing to validate.
• Explain why a more specific M62.4 sibling code does not apply; a brief note such as 'contracture involves thoracic paraspinals, not a separately enumerated extremity site' closes the audit loop.
• Document the clinical basis for contracture versus spasm or joint restriction: passive range-of-motion deficit attributable to the muscle belly itself, not the joint capsule or neural tension.
• Record functional impact (ROM measurements, strength grade, ADL limitation) to support medical necessity for any associated therapeutic or diagnostic procedures.
• If imaging (MRI, ultrasound) or EMG findings corroborate the contracture, reference those results in the diagnosis note — particularly important when M62.48 is supporting EMG medical necessity under CMS LCD A54969.

Common coding pitfalls

The recurring mistakes coders make with M62.48 and adjacent codes.

• Using M62.48 when a laterality-specific sibling code exists (e.g., coding M62.48 for a right forearm contracture instead of M62.431) — the more specific code is required when available.
• Confusing contracture of muscle (M62.48) with contracture of joint (M24.5x); the distinction hinges on whether the restriction is myogenic or arthrogenic — this affects both code selection and treatment justification.
• Defaulting to M62.48 for multiple-site contracture instead of M62.49, which exists specifically for that scenario.
• Coding M62.48 for muscle spasm (R25.2) or generalized muscle tightness without a documented persistent, fixed shortening of the muscle tissue — payers may deny without supporting clinical findings.
• Omitting a code for the underlying cause when one is identifiable (e.g., sequela of stroke, post-surgical scarring) — a 'code also' or 'code first' hierarchy may apply depending on etiology.
