ICD-10 Code M01.X51 – Direct infection of right hip in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X51 – Direct infection of right hip in infectious and parasitic diseases classified elsewhere
What it is
This code identifies direct infection of the right hip joint due to an infectious or parasitic disease classified elsewhere. Use it when the hip infection is documented as secondary to another underlying infection.
Clinical signs
Typical findings include hip pain, swelling, warmth, reduced range of motion, and difficulty bearing weight. Clinical features vary; refer to documentation for the confirmed infectious source and laterality.
When to use this code
Use this code when the provider documents direct infection involving the right hip and links it to another infectious or parasitic condition. You should code the underlying disease as well, when documented. Confirm that the right side is specified and that the infection is not described as postprocedural or traumatic.
Do not use for
Do not use it for nonspecific hip pain, degenerative joint disease, or infection without documented right-sided hip involvement. Check documentation if the record does not clearly state an infectious or parasitic cause.
Coding tip
Verify both the causal infection and the right hip laterality in the note before assigning M01.X51.
