Pilonidal sinus without abscess

This code represents a pilonidal sinus that is present but not currently infected or inflamed to the point of forming an abscess. A pilonidal sinus is a small tunnel or tract in the skin, typically located in the natal cleft (the crease between the buttocks), which may contain hair and skin debris.

Use this code when documentation clearly indicates the presence of a pilonidal sinus without any signs or symptoms of acute infection, such as pus collection, significant erythema, warmth, or fluctuance. This is appropriate for chronic, asymptomatic, or quiescent pilonidal disease.

• Differentiate carefully from an acutely infected pilonidal cyst with abscess formation, which requires a different code.
• Ensure documentation specifies "without abscess" or describes a non-infected state to support this code.
• Consider if any associated complications, such as chronic drainage or pain, are documented, as these may warrant additional codes.
