ICD-10 Code M00.25 – Other streptococcal arthritis, hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.25 – Other streptococcal arthritis, hip
What it is
This code identifies an acute streptococcal infection of the hip joint causing septic arthritis. Use it when documentation specifies the hip and a streptococcal organism other than the code’s excluded types.
Clinical signs
Typical findings include a painful, swollen, warm hip with limited range of motion and difficulty bearing weight. Fever may occur, but clinical features vary; refer to documentation.
When to use this code
Use M00.25 when the provider documents streptococcal septic arthritis affecting the hip, and the record supports the organism and joint site. You may also use it when aspiration, culture, or clear clinician assessment identifies streptococcal involvement. If the note only says “arthritis” or the organism is not specified, check documentation.
Do not use for
Do not use this code for noninfectious arthritis, osteoarthritis, or arthritis due to other organisms. If the hip infection is not clearly streptococcal, check documentation.
Coding tip
Confirm both the joint location and the streptococcal cause before assigning M00.25.
