ICD-10 Code M00.811 – Arthritis due to other bacteria, right shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.811 – Arthritis due to other bacteria, right shoulder
What it is
This code identifies bacterial arthritis affecting the right shoulder joint when the causative organism is not otherwise specified in the code set. It reflects an infectious joint condition, not routine degenerative arthritis.
Clinical signs
Typical findings include a painful, swollen, warm shoulder with limited range of motion. Clinical features vary; refer to documentation for evidence of infection, joint effusion, or organism identification.
When to use this code
Use M00.811 when the record documents septic or infectious arthritis of the right shoulder caused by bacteria other than the specific organisms named in other ICD-10 codes. You should code it when the provider links the right shoulder arthritis to a bacterial cause. If laterality or the bacterial etiology is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for noninfectious arthritis, such as osteoarthritis or rheumatoid arthritis. Also avoid it when the record does not support bacterial involvement or does not specify the right shoulder.
Coding tip
Confirm both the joint site and the documented bacterial cause before coding, and use a more specific organism code if the chart identifies one.
