ICD-10 Code M02.142 – Postdysenteric arthropathy, left hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M02.142 – Postdysenteric arthropathy, left hand
What it is
M02.142 identifies postdysenteric arthropathy affecting the left hand. Use it when joint inflammation in that hand is documented as a reactive arthritis following dysentery or a related intestinal infection.
Clinical signs
Findings may include joint pain, swelling, stiffness, and reduced range of motion in the left hand. Clinical features vary; refer to documentation for the specific joint involvement and the link to prior dysenteric illness.
When to use this code
Use this code when the provider documents postdysenteric arthropathy in the left hand, or clearly describes reactive joint disease after dysentery with left-hand involvement. It is appropriate when the laterality is specified and the condition is not described more generally.
If the record only states arthritis, joint pain, or a remote gastrointestinal infection without a causal link, check documentation before assigning M02.142. Code the documented site and etiology as written.
Do not use for
Do not use this code for nonspecific hand pain, osteoarthritis, or arthritis from another cause. Do not apply it when the left hand is not documented or when postdysenteric cause is not supported.
Coding tip
Verify both the postdysenteric relationship and left-hand laterality in the note before coding M02.142.
