ICD-10 Code M01.X32 – Direct infection of left wrist in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X32 – Direct infection of left wrist in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infectious arthritis or joint infection affecting the left wrist, when the underlying infectious or parasitic disease is coded elsewhere. Use it when the wrist involvement is the documented site, not the primary infection.
Clinical signs
Typical findings include a painful, swollen, warm wrist with reduced motion. Clinical features vary; refer to documentation for the causative infection, laterality, and whether the joint involvement is direct.
When to use this code
Use this code when the record states direct infection of the left wrist and links it to an infectious or parasitic disease classified elsewhere. You should also confirm that the provider documents the left side and that the wrist is the affected joint. If the source infection is coded separately, assign that code as instructed.
Do not use for
Do not use it for nonspecific wrist pain, trauma, or inflammatory arthritis without infection. Check documentation if the note does not clearly identify a direct infectious process.
Coding tip
Verify laterality and the underlying infectious diagnosis before assigning M01.X32.
