Fistula, left hip

This code describes an abnormal, pathological tract or communication originating from the left hip joint. This tract typically connects the joint space to another organ, body cavity, or the skin surface, often resulting from infection, trauma, or surgical complications. It signifies the presence of a persistent opening or channel.

Assign this code when documentation clearly indicates a fistula affecting the left hip joint. This includes scenarios where pus, synovial fluid, or other contents drain from the hip, or imaging studies (e.g., fistulogram, MRI) confirm the presence of an abnormal tract. Supporting documentation should specify the left side and the hip joint involvement.

• Ensure documentation specifies the laterality (left hip) to avoid unspecified coding.
• Distinguish from sinus tracts, which are blind-ended and do not connect two epithelialized surfaces.
• Code any underlying cause or associated infection (e.g., osteomyelitis) separately and sequence appropriately.
