ICD-10 Code M02.229 – Postimmunization arthropathy, unspecified elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.229 – Postimmunization arthropathy, unspecified elbow
What it is
M02.229 identifies joint symptoms in the elbow that occur after immunization. Use it when the record links the arthropathy to a prior vaccine reaction and the elbow is the unspecified site.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see elbow pain, swelling, stiffness, or reduced range of motion after vaccination, with clinician notation supporting a postimmunization cause.
When to use this code
Use this code when the provider documents postimmunization arthropathy involving the elbow and does not specify right or left. It fits cases where the joint complaint is attributed to vaccination rather than trauma, infection, or another inflammatory disorder.
Check the note for timing and causal wording. If the elbow site is laterality-specific, or if the arthropathy is due to another cause, choose the more accurate code.
Do not use for
Do not use this code for nonspecific elbow pain without a documented postimmunization relationship. Also avoid it when the condition is better described as trauma, arthritis, or another post-vaccination reaction.
Coding tip
Confirm both the vaccine association and the elbow site in the provider record before assigning M02.229.
