ICD-10 Code M00.151 – Pneumococcal arthritis, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.151 – Pneumococcal arthritis, right hip
What it is
M00.151 identifies septic arthritis of the right hip caused by Streptococcus pneumoniae. Use it when the chart documents pneumococcal infection involving that specific joint.
Clinical signs
Typical findings include acute hip pain, swelling, warmth, and reduced range of motion. Clinical features vary; refer to documentation for organism confirmation and laterality.
When to use this code
Use M00.151 when the provider documents pneumococcal arthritis affecting the right hip, or when the organism and joint are clearly identified in the assessment. It fits confirmed infection of the synovial joint, not nonspecific joint pain or suspected infection. Check documentation if laterality or causative organism is unclear.
Do not use for
Do not use this code for arthritis of another joint, unspecified septic arthritis, or joint pain without infection. If documentation does not identify pneumococcus or the right hip, check documentation.
Coding tip
Verify both the organism and the exact joint before assigning M00.151.
