ICD-10 Code M01.X22 – Direct infection of left elbow in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X22 – Direct infection of left elbow in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infectious process affecting the left elbow, with the infection classified elsewhere. Use it when the elbow joint is involved as part of a known infectious or parasitic disease.
Clinical signs
Typical findings include elbow pain, swelling, warmth, tenderness, and reduced range of motion. Clinical features vary; refer to documentation for the underlying infectious diagnosis and laterality.
When to use this code
Use M01.X22 when the provider documents direct infection of the left elbow and links it to another infectious or parasitic condition. It is appropriate when the elbow involvement is not coded as a separate primary disease. Confirm that the left side is specified in the record.
Do not use for
Do not use this code for nonspecific joint pain, trauma, or degenerative arthritis of the elbow. Check documentation if the infection is not clearly tied to a condition classified elsewhere.
Coding tip
Report the underlying infectious disease first, then add this code only when the left elbow infection is explicitly documented.
