Symptomatic late syphilis of other respiratory organs

This code signifies a diagnosis of late-stage syphilis presenting with symptomatic involvement of respiratory organs other than the larynx, trachea, or lung. This includes conditions like syphilitic rhinitis, pharyngitis, or sinusitis. These manifestations are typically chronic and can lead to significant tissue damage if left untreated.

Use this code when documentation clearly indicates a diagnosis of late syphilis affecting the nasal passages, pharynx, or paranasal sinuses, and the patient is experiencing related symptoms. This diagnosis is usually supported by serologic tests confirming syphilis and clinical findings specific to the affected respiratory organ.

• Ensure documentation specifies "late" syphilis and symptomatic involvement of a non-laryngeal/tracheal/pulmonary respiratory organ.
• Distinguish from congenital syphilis or early/latent syphilis without respiratory symptoms.
• Code any associated manifestations or complications of the respiratory involvement separately, if applicable.
