A50.57

What This Code Means

A deformity of the nose caused by syphilis where the bridge of the nose collapses inward, creating a saddle-shaped appearance. This is a late manifestation of untreated syphilis that causes permanent structural damage to the nasal bones and cartilage.

Coding Tips

• •This code is used for late syphilis manifestations; ensure the patient has documented syphilis diagnosis and that this is a late-stage complication, not an acute infection
• •Do not use this code for saddle nose deformities from other causes (trauma, leprosy, granulomatosis); verify syphilitic etiology is documented in the medical record
