ICD-10 Code M02.239 – Postimmunization arthropathy, unspecified wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.239 – Postimmunization arthropathy, unspecified wrist
What it is
M02.239 identifies arthropathy that occurs after immunization and is limited to an unspecified wrist. Use it when the record links the wrist joint problem to a recent vaccine, but does not name a more specific wrist or joint detail.
Clinical signs
Typical findings include wrist pain, swelling, stiffness, or reduced range of motion after vaccination. Clinical features vary; refer to documentation for the timing and whether the provider attributes the joint symptoms to immunization.
When to use this code
Use this code when the clinician documents a postimmunization arthropathy affecting the wrist and does not specify left or right wrist. It also fits cases where the joint reaction is described as vaccine-related, but the chart lacks a more precise arthropathy code. Check documentation if the relationship to immunization is unclear.
Do not use for
Do not use this code for nonspecific wrist pain without a documented postimmunization cause. Also avoid it when the condition is better described by another reactive or infectious arthropathy diagnosis.
Coding tip
Confirm both the vaccine association and the wrist location in the note before assigning M02.239.
