ICD-10 Code M00.011 – Staphylococcal arthritis, right shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.011 – Staphylococcal arthritis, right shoulder
What it is
M00.011 identifies a staphylococcal infection of the right shoulder joint. It is used when the arthritis is caused by Staphylococcus and documented as affecting the right shoulder.
Clinical signs
Typical findings include a painful, swollen, and warm shoulder with limited range of motion. Fever or other signs of infection may be present, but clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents staphylococcal septic arthritis or infected arthritis in the right shoulder. It applies when the right shoulder is the specified joint and Staphylococcus is the documented cause.
If the record only states “arthritis” without an infectious cause, or the affected side is not documented, check documentation before assigning M00.011. Confirm that the diagnosis is current and not merely suspected.
Do not use for
Do not use this code for noninfectious arthritis, such as osteoarthritis or rheumatoid arthritis. Also avoid it when the infection is in a different joint or the organism is not documented as Staphylococcus.
Coding tip
Match both the organism and the laterality exactly; if either is missing, check documentation before coding.
