Personal history of congenital malform of resp sys

This code indicates that a patient has a past medical history of a birth defect affecting their respiratory system, which has since been corrected or resolved. This could include conditions like a repaired tracheoesophageal fistula, corrected congenital diaphragmatic hernia, or surgically addressed airway malformations. The patient is no longer actively experiencing the congenital malformation but has a history of it.

Apply this code when documenting a patient's history of a congenital respiratory system anomaly that has been successfully treated or corrected. This is relevant for ongoing care, risk assessment, or when the history impacts current medical management, even if the patient is asymptomatic from the original defect. It should be used as a secondary diagnosis to provide comprehensive patient history.

• Do not use this code for active, uncorrected congenital malformations; use the appropriate Q-code instead.
• Ensure the medical record clearly states the congenital malformation was "corrected" or "repaired" to justify this history code.
• Always sequence this as a secondary diagnosis, as it represents a historical condition, not a current illness or reason for the encounter.
