ICD-10 Code M61.01: Myositis ossificans traumatica, shoulder
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Diseases of the musculoskeletal system and connective tissue (M00-M99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes myositis ossificans traumatica. 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 myositis ossificans traumatica, shoulder in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
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.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Orthopedic, sports-medicine, rehabilitation, and imaging workflows where post-traumatic heterotopic ossification or myositis ossificans is documented.
- Coding and utilization-review workflows where the record supports myositis ossificans traumatica and the final code changes based on region, laterality, or multiple-site involvement.
Common management context
- Evaluation often includes pain and motion-limitation review, prior-trauma history, imaging context, and planning for rehabilitation or orthopedic follow-up.
- Documentation usually becomes more specific when the chart identifies the exact muscle region, laterality, and whether one or multiple sites are involved.
- Specialist context already linked on this page includes Orthopedic Specialist, Rheumatologist.
🔍Key distinctions
Important notes
- These ICD-10 codes are reserved for traumatic myositis ossificans rather than nontraumatic heterotopic ossification or other muscle disorders.
- Region, laterality, and whether multiple sites are involved all affect final code specificity inside this family.
- Muscle-region detail matters here because shoulder, upper-arm, forearm, hand, thigh, lower-leg, ankle-foot, other-site, and multiple-site myositis ossificans traumatica are coded separately when the chart names the affected region more specifically.
- Documentation that describes myositis ossificans traumatica is coded differently from nontraumatic heterotopic ossification, muscle rupture, or other soft-tissue disorders.
