ICD-10 Code M01.X52 – Direct infection of left hip in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X52 – Direct infection of left hip in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infection of the left hip joint that occurs as part of another infectious or parasitic disease. Use it when the hip infection is documented as secondary to a separate underlying condition.
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 joint involved and the linked infectious cause.
When to use this code
Use M01.X52 when the provider documents direct infection of the left hip and states it is associated with an infectious or parasitic disease classified elsewhere. Code the underlying infection first when required by the record and ICD-10-CM guidance. Confirm laterality and that the hip, not the surrounding tissue, is the affected site.
Do not use for
Do not use this code for nonspecific hip pain, osteoarthritis, or infection limited to skin or soft tissue around the hip. Check documentation if the record does not clearly identify a direct joint infection.
Coding tip
Verify the causal infection and laterality in the note before assigning M01.X52.
