ICD-10 Code M02.222 – Postimmunization arthropathy, left elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.222 – Postimmunization arthropathy, left elbow
What it is
This code identifies joint inflammation or pain in the left elbow that occurs after immunization. It is used when the record links the arthropathy to a prior vaccine exposure.
Clinical signs
Typical findings include elbow pain, swelling, stiffness, and reduced range of motion after vaccination. Clinical features vary; refer to documentation for the timing and the documented relationship to immunization.
When to use this code
Use M02.222 when the provider documents postimmunization arthropathy affecting the left elbow. The note should support both the post-vaccine cause and the specific joint involved. If the affected side or causal link is unclear, check documentation before coding.
Do not use for
Do not use this code for nonspecific arm pain, routine post-vaccination soreness, or arthropathy without a documented immunization link. Also avoid it when a different joint or side is specified.
Coding tip
Verify that the record names the left elbow and explicitly connects the arthropathy to immunization before assigning M02.222.
