ICD-10 Code M02.231 – Postimmunization arthropathy, right wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.231 – Postimmunization arthropathy, right wrist
What it is
This code identifies joint inflammation or pain in the right wrist that occurs after immunization. Use it when the documentation links the arthropathy to a vaccine reaction and specifies the right wrist.
Clinical signs
Clinical features vary; refer to documentation. Typical charting may note wrist pain, swelling, stiffness, or reduced range of motion after vaccination, with the right side clearly identified.
When to use this code
Use M02.231 when the provider documents postimmunization arthropathy affecting the right wrist. It fits cases where the relationship to vaccination is stated in the record, not merely suspected. Code the condition only when the laterality and postimmunization cause are both documented.
Do not use for
Do not use this code for nonspecific wrist pain, arthritis unrelated to immunization, or symptoms without a documented vaccine connection. Check documentation if the affected side is not stated.
Coding tip
Always verify that the record names both the vaccine-related cause and the right wrist before assigning M02.231.
