ICD-10 Code M01.X11 – Direct infection of right shoulder in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X11 – Direct infection of right shoulder in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infection affecting the right shoulder joint that occurs as part of another infectious or parasitic disease. Use it when the shoulder infection is documented as secondary to a separate underlying condition.
Clinical signs
Typical findings include shoulder pain, swelling, warmth, reduced range of motion, and tenderness. Clinical features vary; refer to documentation for evidence that the infection involves the right shoulder.
When to use this code
Use M01.X11 when the record states a direct infectious process in the right shoulder linked to an infectious or parasitic disease elsewhere. You should also confirm that the provider identifies the right shoulder as the affected site and the infection as direct, not reactive.
Code the underlying infectious or parasitic disease separately when documented. If the note only says shoulder pain, arthritis, or nonspecific infection without laterality or direct involvement, check documentation before assigning this code.
Do not use for
Do not use this code for noninfectious shoulder arthritis, trauma, or unspecified joint pain. It is also incorrect when the chart does not support direct infection of the right shoulder.
Coding tip
Verify laterality and the causal infectious disease in the record before coding, and sequence the underlying condition when required.
