ICD-10 Code M02.251 – Postimmunization arthropathy, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.251 – Postimmunization arthropathy, right hip
What it is
M02.251 identifies joint inflammation in the right hip that occurs after immunization. Use it when the record links the arthropathy to a prior vaccine reaction.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include hip pain, stiffness, swelling, and reduced range of motion after vaccination, with provider assessment supporting a postimmunization cause.
When to use this code
Use this code when the clinician documents reactive arthropathy of the right hip due to immunization. It fits cases where the right hip is specifically identified and the vaccine association is clear in the note. If laterality or causation is not stated, check documentation.
Do not use for
Do not use this code for nonspecific hip pain, arthritis without a vaccine link, or arthropathy affecting another joint. If the record does not support a postimmunization cause, choose a different diagnosis.
Coding tip
Confirm both the postimmunization relationship and right-sided hip involvement before assigning M02.251.
