ICD-10 Code M00.051 – Staphylococcal arthritis, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.051 – Staphylococcal arthritis, right hip
What it is
This code identifies a staphylococcal infection causing arthritis in the right hip joint. Use it when documentation specifies the organism as Staphylococcus and the affected joint as the right hip.
Clinical signs
Typical findings include acute joint pain, swelling, warmth, and reduced range of motion. Fever or systemic illness may occur, but clinical features vary; refer to documentation.
When to use this code
Use M00.051 when the provider documents septic or infectious arthritis of the right hip due to Staphylococcus. It is appropriate when the organism and joint laterality are clearly stated in the record. Check documentation if the note only says “infectious arthritis” without the organism.
Do not use for
Do not use this code for noninfectious inflammatory arthritis or for arthritis caused by another organism. If the hip laterality is not documented, or the cause is unclear, check documentation.
Coding tip
Confirm both the staphylococcal cause and right-sided hip involvement before assigning M00.051.
