ICD-10 Code M02.23 – Postimmunization arthropathy, wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.23 – Postimmunization arthropathy, wrist
What it is
This code identifies joint inflammation or pain in the wrist that occurs after immunization. It is used when the documentation links the arthropathy to a vaccine reaction.
Clinical signs
Typical findings include wrist pain, swelling, stiffness, and reduced range of motion after vaccination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents postimmunization arthropathy affecting the wrist and the causal relationship to vaccination is clear. It applies to a documented wrist joint reaction, not to general post-vaccine soreness or an unrelated arthritis diagnosis.
Do not use for
Do not use it for nonspecific arm pain, injection-site discomfort, or arthritis without a documented vaccine link. Check documentation if the affected joint or cause is unclear.
Coding tip
Confirm both the postimmunization cause and the wrist site in the record before assigning M02.23.
