ICD-10 Code M00.119 – Pneumococcal arthritis, unspecified shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.119 – Pneumococcal arthritis, unspecified shoulder
What it is
M00.119 identifies pneumococcal infection of the shoulder joint when the site is unspecified. It is used for septic arthritis caused by Streptococcus pneumoniae affecting the shoulder.
Clinical signs
Typical findings include acute joint pain, swelling, warmth, and restricted shoulder motion. Fever or other systemic signs may occur, but clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents pneumococcal septic arthritis of the shoulder and does not specify right or left side. You should also use it when the provider clearly identifies the organism as pneumococcus. Check documentation if the joint is described only as shoulder pain or effusion without infection.
Do not use for
Do not use this code for noninfectious arthritis, other organisms, or shoulder pain without confirmed joint infection. Do not use it when the laterality is documented and a more specific code applies.
Coding tip
Verify both the organism and the joint site in the note before assigning M00.119.
