ICD-10 Code M00.251 – Other streptococcal arthritis, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.251 – Other streptococcal arthritis, right hip
What it is
M00.251 identifies a streptococcal infection causing arthritis in the right hip. Use it when the record specifies the organism as streptococcal and the affected joint as the right hip.
Clinical signs
Typical findings include acute hip pain, swelling, warmth, and limited range of motion. Fever and elevated inflammatory markers may occur, but clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents septic arthritis of the right hip due to streptococcal infection. It also applies when the note clearly links a streptococcal organism to the joint infection, even if “other” streptococcal species is specified.
If laterality and organism are both documented, code them exactly as stated. Check documentation when the organism is not named, when the joint is different, or when the arthritis is described as noninfectious.
Do not use for
Do not use this code for arthritis caused by organisms other than streptococci or for unspecified infectious arthritis. It is also wrong for degenerative, inflammatory, or traumatic hip arthritis.
Coding tip
Verify both the streptococcal cause and right hip laterality in the provider note before assigning M00.251.
