ICD-10 Code M00.14 – Pneumococcal arthritis, hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.14 – Pneumococcal arthritis, hand
What it is
This code identifies a bacterial joint infection in the hand caused by Streptococcus pneumoniae. It reflects septic arthritis affecting one or more hand joints.
Clinical signs
Typical findings include a painful, swollen, warm hand joint with reduced range of motion. Clinical features vary; refer to documentation for organism confirmation and the specific joint involved.
When to use this code
Use M00.14 when the provider documents pneumococcal septic arthritis in a hand joint. Apply it when the organism is identified as S. pneumoniae and the site is the hand, not another joint. Check documentation if the record only says septic arthritis without the organism.
Do not use for
Do not use this code for arthritis caused by other organisms or for noninfectious inflammatory arthritis. Do not assign it if the hand joint is not specified or pneumococcal infection is not documented.
Coding tip
Match both elements in the note: pneumococcal cause and hand joint location.
