ICD-10 Code M62.062: Separation of muscle (nontraumatic), left lower leg

M62.062 is a billable ICD-10 diagnosis code used to classify Separation of muscle (nontraumatic), left lower leg in medical records and claims. You may see this code in hospital records, discharge summaries, insurance claims, encounter documentation, referrals, or other healthcare billing and coding records. ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the musculoskeletal system and connective tissue (M00-M99).

What is this code?

ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the musculoskeletal system and connective tissue (M00-M99).

šŸ“‹Clinical overview

This ICD-10 code is commonly used when documentation describes nontraumatic separation of muscle. The most accurate code depends on the affected muscle region and whether laterality is documented.

When is it used?

  • May be used when a clinician documents separation of muscle (nontraumatic), left lower leg in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.
  • This code can be used as a clinically usable diagnosis entry in standardized coding workflows.

What it does not mean

  • A code alone does not explain severity, treatment plan, or outcome.
  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.

šŸ©ŗClinical context

When commonly used
  • Orthopedic, sports-medicine, rehabilitation, and imaging workflows where nontraumatic muscle separation is part of the documented problem list.
  • Coding and utilization-review workflows where the chart supports nontraumatic muscle separation but the final code changes based on anatomic region and laterality.
Common management context
  • Evaluation often includes physical examination, pain and function review, imaging context when needed, and planning for activity modification or rehabilitation.
  • Documentation usually becomes more specific when the chart names the exact muscle region, laterality, severity, or another nontraumatic muscle-injury pattern.
  • Specialist context already linked on this page includes Orthopedic Specialist, Rheumatologist.

šŸ”Key distinctions

Important notes
  • These ICD-10 codes are site-sensitive, so documentation that clearly names the affected muscle region usually determines the final code.
  • Nontraumatic muscle separation is coded separately from other nontraumatic muscle rupture and from nontraumatic ischemic infarction of muscle.
  • Anatomic region detail matters here because shoulder, upper-arm, forearm, hand, thigh, lower-leg, ankle-and-foot, and other-site muscle conditions are coded separately when the chart names the affected region more specifically.
  • Laterality matters here because right-sided, left-sided, and unspecified-side muscle involvement is coded separately when the affected region is documented more precisely.
  • Documentation that describes separation of muscle (nontraumatic) is coded differently from other nontraumatic muscle rupture or nontraumatic ischemic infarction of muscle.
