ICD-10 Code M02.221 – Postimmunization arthropathy, right elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.221 – Postimmunization arthropathy, right elbow
What it is
This code identifies joint inflammation or pain in the right elbow that occurs after immunization. Use it when the documentation links the arthropathy to a vaccine reaction and specifies the right elbow.
Clinical signs
Typical findings include elbow pain, swelling, stiffness, and reduced range of motion after vaccination. Clinical features vary; refer to documentation.
When to use this code
Use M02.221 when the provider documents postimmunization arthropathy affecting the right elbow. The record should connect the joint symptoms to a prior immunization and identify the right side. If laterality or the vaccine relationship is unclear, check documentation.
Do not use for
Do not use this code for nonspecific elbow pain, unrelated arthritis, or postvaccination reactions without joint involvement. Check documentation if the condition is described differently or another joint is involved.
Coding tip
Confirm both the postimmunization cause and right elbow laterality before assigning M02.221.
