ICD-10 Code M02.241 – Postimmunization arthropathy, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.241 – Postimmunization arthropathy, right hand
What it is
M02.241 identifies joint inflammation or arthropathy affecting the right hand that is attributed to a prior immunization. Use this code when the provider documents a postimmunization joint reaction in the right hand.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include localized joint pain, swelling, stiffness, or reduced hand motion after vaccination, with the right hand specifically identified.
When to use this code
Use M02.241 when the record clearly links the arthropathy to immunization and names the right hand as the affected site. You should code it from provider documentation, not from suspicion alone. If the laterality or vaccine relationship is unclear, check documentation.
Do not use for
Do not use this code for unspecified hand involvement, generalized arthralgia, or joint pain without a documented postimmunization cause. Check documentation if the reaction is described as another musculoskeletal condition.
Coding tip
Verify both the vaccine-related cause and right-hand laterality before assigning M02.241.
