ICD-10 Code M02.149 – Postdysenteric arthropathy, unspecified hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.149 – Postdysenteric arthropathy, unspecified hand
What it is
M02.149 identifies postdysenteric arthropathy affecting an unspecified hand. Use it when inflammatory joint disease is documented as a complication after dysentery and the hand is the involved site.
Clinical signs
Typical findings include joint pain, swelling, stiffness, and reduced range of motion in the hand. Clinical features vary; refer to documentation for the specific hand joints involved and the link to prior dysenteric infection.
When to use this code
Use this code when the record clearly states postdysenteric arthropathy and does not identify right or left hand. It also fits when the provider documents reactive joint symptoms after dysentery with hand involvement. If the diagnosis is uncertain or the hand is not specified, check documentation.
Do not use for
Do not use this code for arthritis from other infectious, autoimmune, or degenerative causes. Do not assign it if the condition is documented in another joint or if the postdysenteric link is not stated.
Coding tip
Verify both the postdysenteric cause and the hand site; if laterality is documented, choose the more specific code.
