ICD-10 Code M00.019 – Staphylococcal arthritis, unspecified shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.019 – Staphylococcal arthritis, unspecified shoulder
What it is
This code identifies staphylococcal arthritis affecting the shoulder, with no side specified. It indicates a joint infection caused by Staphylococcus species, documented in the shoulder joint.
Clinical signs
Typical findings include a painful, swollen, warm shoulder with reduced range of motion. Fever or systemic illness may occur, but clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents staphylococcal infection of the shoulder joint and does not specify left or right. It also fits cases described as septic arthritis of the shoulder due to Staphylococcus when the shoulder laterality is not stated. Check documentation if the organism or joint site is unclear.
Do not use for
Do not use this code for shoulder pain, bursitis, or noninfectious arthritis. If the record specifies a different joint, organism, or laterality, choose the documented code instead.
Coding tip
Confirm both the infecting organism and that the shoulder joint is the site before assigning M00.019.
