ICD-10 Code M02.259 – Postimmunization arthropathy, unspecified hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.259 – Postimmunization arthropathy, unspecified hip
What it is
This code identifies arthropathy affecting the hip that is documented as occurring after immunization, with no laterality specified. Use it when the record links the joint problem to a prior vaccine and does not provide a more specific hip designation.
Clinical signs
Clinical features may include hip pain, stiffness, swelling, or reduced range of motion after immunization. Clinical features vary; refer to documentation.
When to use this code
Use M02.259 when the provider documents postimmunization arthropathy involving the hip and does not specify right or left. It is appropriate when the diagnosis is clearly attributed to immunization-related arthropathy rather than another inflammatory, traumatic, or degenerative joint condition.
Do not use for
Do not use this code for nonspecific hip pain without a documented postimmunization cause. Also avoid it when the record identifies another diagnosis, such as septic arthritis, osteoarthritis, or reactive arthritis from a different trigger. Check documentation.
Coding tip
Confirm both the postimmunization relationship and the unspecified hip location before assigning M02.259.
