ICD-10 Code M19.92: Post-traumatic osteoarthritis, unspecified site
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).
šClinical overview
This ICD-10 code is commonly used when documentation describes post-traumatic osteoarthritis. The most accurate code depends on the affected joint site and whether laterality is documented.
When is it used?
- May be used when a clinician documents post-traumatic osteoarthritis, unspecified site 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.
š©ŗClinical context
- Orthopedic, rehabilitation, primary-care, and utilization-review workflows where degenerative joint disease is explicitly linked to prior trauma.
- Coding workflows where the record supports post-traumatic osteoarthritis and the final code changes based on joint site or laterality.
- Evaluation often includes joint pain and function review, prior-injury history, imaging context, and planning for orthopedic follow-up, rehabilitation, or symptom-directed management.
- Documentation usually becomes more specific when the chart identifies the exact joint site, laterality, or another post-traumatic versus primary-degenerative joint context.
- Specialist context already linked on this page includes Orthopedic Specialist, Rheumatologist.
šKey distinctions
- These ICD-10 codes are reserved for post-traumatic osteoarthritis rather than primary osteoarthritis or broader traumatic-arthropathy descriptions.
- Joint-site and laterality detail drive most of the code specificity inside this family.
- This title reflects broad joint-site detail; if the chart clearly identifies the affected joint, a more specific post-traumatic-osteoarthritis code may be used.
- Documentation that describes post-traumatic osteoarthritis is coded differently from primary osteoarthritis, traumatic arthropathy, or nontraumatic joint derangement.
