ICD-10 Code M02.219 – Postimmunization arthropathy, unspecified shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.219 – Postimmunization arthropathy, unspecified shoulder
What it is
M02.219 identifies joint inflammation or pain in the shoulder that occurs after immunization, when the shoulder is not further specified. Use it when the record links the arthropathy to a vaccine reaction.
Clinical signs
Typical findings include shoulder pain, swelling, stiffness, and reduced range of motion after a recent vaccination. Clinical features vary; refer to documentation for the exact joint findings and laterality details.
When to use this code
Use this code when the provider documents postimmunization arthropathy involving an unspecified shoulder and does not identify a more specific shoulder site. It also fits when the note clearly connects the arthropathy to immunization. Check documentation if the cause is uncertain or another diagnosis is recorded.
Do not use for
Do not use it for routine post-vaccine soreness without documented arthropathy, or for shoulder pain from another cause. If the shoulder is specified elsewhere in the record, code that more specific option instead.
Coding tip
Confirm both the vaccine association and the shoulder site before assigning M02.219.
