Acquired deformity of nose

This code describes a non-congenital alteration in the normal anatomical structure of the nose, resulting in a visible or palpable distortion. This deformity can arise from various causes, including trauma, infection, inflammation, or previous surgical interventions, affecting the nasal bones, cartilage, or soft tissues.

Apply this code when documentation clearly indicates an acquired, rather than congenital, deformity of the nose. This includes conditions such as saddle nose deformity, post-traumatic nasal asymmetry, or deformities resulting from tumor resection or infection. Supporting documentation should detail the nature and origin of the deformity.

• Differentiate carefully between acquired and congenital nasal deformities; congenital deformities are classified elsewhere.
• Ensure the documentation specifies that the deformity is not a deviated nasal septum, as this is an Excludes2 note.
• Look for specific causes of the acquired deformity in the medical record, as these may require additional codes.
