ICD-10 Code M01.X2 – Direct infection of elbow in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X2 – Direct infection of elbow in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infectious arthropathy affecting the elbow joint, where the joint infection is classified under another infectious or parasitic disease. Use it when the elbow is involved as part of a documented underlying infection.
Clinical signs
Typical findings include elbow pain, swelling, warmth, and limited range of motion. Clinical features vary; refer to documentation for the causative infectious or parasitic condition and confirm that the elbow joint is directly involved.
When to use this code
Use M01.X2 when the record documents direct infection of the elbow linked to an infectious or parasitic disease classified elsewhere. You should code it when the provider clearly identifies the elbow as the infected joint, not just a reactive or nonspecific arthropathy. Check documentation for the underlying infection and any site specificity.
Do not use for
Do not use this code for traumatic elbow pain, degenerative joint disease, or nonspecific arthritis. It is also inappropriate when the chart does not support direct joint infection or when the elbow is only suspected to be involved.
Coding tip
Verify the underlying infectious diagnosis and document that the elbow is directly infected before assigning M01.X2.
