ICD-10 Code M01.X29 – Direct infection of unspecified elbow in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X29 – Direct infection of unspecified elbow in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infectious involvement of the unspecified elbow joint when the underlying infectious or parasitic disease is classified elsewhere. It is used for joint infection linked to another documented condition, not as the primary disease code.
Clinical signs
Typical findings include elbow pain, swelling, warmth, reduced range of motion, and tenderness. Clinical features vary; refer to documentation, and confirm the underlying infection or parasitic disease is recorded elsewhere in the chart.
When to use this code
Use this code when the provider documents direct infection of the elbow and names an infectious or parasitic disease as the cause. You should also have documentation that the elbow is unspecified, not left or right. Code the underlying condition separately when instructed by the record.
Do not use for
Do not use this code for traumatic elbow pain, inflammatory arthritis without infection, or septic arthritis when the documentation does not link it to another infectious or parasitic disease. Check documentation if the elbow side is specified.
Coding tip
Verify both the joint site and the causal infection are documented before assigning M01.X29.
