M62.48

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.

Source · Editorial brief grounded in 4 cited references ↓

  • 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.

Source · Editorial brief grounded in CDC ICD-10-CM tabular guidance, AAOS coding references, and cited references ↓

  • 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.

Clinical context

Source · Editorial summary grounded in 4 cited references ↓

M62.48 is the residual 'other site' code under M62.4 (Contracture of muscle). Use it only after confirming the affected muscle group is not covered by a more specific sibling code: M62.411–M62.412 (shoulder), M62.421–M62.422 (upper arm), M62.431–M62.432 (forearm), M62.441–M62.442 (hand), M62.451–M62.452 (thigh), M62.461–M62.462 (lower leg), M62.471–M62.472 (ankle/foot), M62.49 (multiple sites). Sites that legitimately land here include trunk muscles (paraspinals, intercostals), cervical musculature, and pelvic floor or hip girdle muscles when contracture — not joint pathology — is the primary finding.

In orthopedic practice, M62.48 appears most often when a provider documents cervical or thoracic paraspinal contracture as a discrete musculoskeletal diagnosis, or when pelvic girdle muscle tightness is the coded condition rather than an underlying spinal or hip disorder. It also supports medical necessity for nerve conduction studies and EMG when neuromuscular involvement is being evaluated — CMS LCD A54969 explicitly lists M62.48 among supporting ICD-10-CM codes for those procedures.

Do not use M62.48 as a catch-all for any muscle tightness or spasm. Muscle spasm codes (R25.2) and contracture-of-joint codes (M24.5x) are separately classified; coding the wrong category invites audit risk and can misrepresent the clinical picture. If the contracture affects multiple distinct sites, M62.49 is the correct choice.

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 4 cited references ↓

01What sites actually belong under M62.48?
M62.48 covers muscle contracture at sites not enumerated elsewhere in M62.4 — practically speaking, trunk muscles (paraspinals, intercostals, abdominals), cervical musculature, and pelvic girdle muscles. Any extremity site has its own specific code in M62.41–M62.47.
02When should I use M62.49 instead of M62.48?
Use M62.49 (contracture of muscle, multiple sites) when the documented contracture affects two or more distinct anatomical regions simultaneously. M62.48 is for a single 'other' site.
03Can M62.48 support medical necessity for EMG or nerve conduction studies?
Yes. CMS LCD A54969 (Nerve Conduction Studies and Electromyography) explicitly lists M62.48 among ICD-10-CM codes that support medical necessity for those procedures, alongside the other M62.4x contracture codes.
04How do I distinguish M62.48 (muscle contracture) from M24.5x (joint contracture)?
Muscle contracture (M62.48) is a fixed shortening of the muscle belly or myotendinous unit itself. Joint contracture (M24.5x) is a restriction of the joint capsule or periarticular structures. Clinically, muscle contracture typically shows a stretch end-feel and is position-dependent; document the provider's clinical reasoning explicitly.
05Is M62.48 appropriate for cervical paraspinal contracture?
Yes — if the provider documents a true myogenic contracture of the cervical paraspinals (not spasm, not joint restriction), M62.48 is the correct code because the cervical region is not listed among the specific M62.4 sibling codes.
06Should I also code the underlying cause when using M62.48?
Yes, when the etiology is known and a coding hierarchy applies. For example, contracture as a sequela of a neurological condition should follow a 'code first' or 'code also' instruction for the underlying disorder. Review the M62.4 category notes in the FY2026 Tabular List.
07What MS-DRGs does M62.48 map to for inpatient claims?
Under MS-DRG v43.0, M62.48 groups to DRG 555 (Signs and symptoms of musculoskeletal system and connective tissue with MCC) or DRG 556 (without MCC), depending on documented comorbidities.

Mira AI Scribe

The Mira AI Scribe captures the specific muscle or muscle group involved, the clinician's ROM measurements, the basis for distinguishing myogenic contracture from joint restriction, and any corroborating imaging or EMG findings. This prevents the encounter from being coded as unspecified muscle tightness or defaulting to the wrong category (joint contracture or muscle spasm), both of which can trigger a medical necessity denial or payer audit.
