ICD-10 Code M00.01 – Staphylococcal arthritis, shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.01 – Staphylococcal arthritis, shoulder
What it is
M00.01 identifies a staphylococcal infection of the shoulder joint causing septic arthritis. Use it when documentation states the shoulder joint is infected by Staphylococcus species.
Clinical signs
Typical findings include acute shoulder pain, swelling, warmth, limited range of motion, and pain with movement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents staphylococcal septic arthritis limited to the shoulder. It fits confirmed or clearly documented presumed infection of that joint by Staphylococcus. If the record names another joint or only mentions bacteremia without joint involvement, check documentation.
Do not use for
Do not use it for noninfectious shoulder arthritis, such as osteoarthritis or rheumatoid arthritis. It also should not be used when the organism is not Staphylococcus or the shoulder joint is not specified.
Coding tip
Verify both the organism and the joint site in the note before assigning M00.01.
