ICD-10 Code M02.272 – Postimmunization arthropathy, left ankle and foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.272 – Postimmunization arthropathy, left ankle and foot
What it is
M02.272 identifies joint inflammation in the left ankle and foot that follows immunization. Use it when the record links the arthropathy to a vaccine or other immunizing agent.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include joint pain, swelling, stiffness, and reduced range of motion in the affected left ankle or foot.
When to use this code
Use this code when the clinician documents postimmunization arthropathy affecting the left ankle and foot, and the relationship to vaccination is clear. You should also confirm laterality and the specific joint site in the note. Check documentation if the cause is uncertain or the condition is described only as generalized arthralgia.
Do not use for
Do not use this code for nonspecific joint pain after vaccination without documented arthropathy. Do not assign it if the problem is due to trauma, infection, or another inflammatory arthritis.
Coding tip
Verify both the postimmunization cause and the left ankle/foot location before coding, because laterality and etiology are both required.
