ICD-10 Code M00.05 – Staphylococcal arthritis, hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.05 – Staphylococcal arthritis, hip
What it is
M00.05 identifies a staphylococcal infection of the hip joint causing septic arthritis. Use it when the record specifies Staphylococcus as the organism and the hip is the affected joint.
Clinical signs
Typical findings include acute hip pain, swelling, warmth, reduced range of motion, and difficulty bearing weight. Clinical features vary; refer to documentation for the organism and joint involvement.
When to use this code
Use this code when the provider documents staphylococcal septic arthritis limited to the hip. It may appear after aspiration, culture, or operative findings confirm the organism. Code the documented laterality only if a more specific hip code is available and supported.
Do not use for
Do not use it for noninfectious arthritis, unspecified septic arthritis, or infections of another joint. If the organism is not documented as Staphylococcus, check documentation.
Coding tip
Verify both the causative organism and the involved joint before assigning M00.05.
