ICD-10 Code M00.141 – Pneumococcal arthritis, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.141 – Pneumococcal arthritis, right hand
What it is
This code identifies a pneumococcal joint infection affecting the right hand. Use it when Streptococcus pneumoniae is documented as the cause of septic arthritis in that location.
Clinical signs
Typical findings include a painful, swollen, warm, and limited right-hand joint with acute onset. Clinical features vary; refer to documentation for organism confirmation and the specific joint involved.
When to use this code
Use M00.141 when the record clearly states pneumococcal arthritis in the right hand, such as the wrist or a hand joint, and the organism is documented. Code it from provider documentation, not from suspicion alone. If the site or organism is unclear, check documentation.
Do not use for
Do not use this code for arthritis caused by another organism, noninfectious inflammatory arthritis, or unspecified septic arthritis. If the right-hand site is not documented, check documentation before assigning this code.
Coding tip
Confirm both the organism and the right-hand location are documented before coding.
