ICD-10 Code M00.041 – Staphylococcal arthritis, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.041 – Staphylococcal arthritis, right hand
What it is
This code identifies a staphylococcal infection causing arthritis in the right hand. Use it when documentation specifies the organism and the affected side.
Clinical signs
Typical findings include a painful, swollen, warm joint with reduced motion. Clinical features vary; refer to documentation, especially when the infected hand joint is named.
When to use this code
Use M00.041 when the provider documents septic arthritis of a right-hand joint due to Staphylococcus. It also applies when the record clearly links the arthritis to a staphylococcal infection and the right hand is identified. Check documentation if the organism is not specified.
Do not use for
Do not use this code for arthritis of another cause, such as gout or rheumatoid disease. It is also incorrect if the site is not the right hand or if staphylococcal infection is not documented.
Coding tip
Verify both the organism and laterality in the note before assigning M00.041.
