Pers hx congen diaphragm hernia/oth congen diaphragm malform

This code indicates a patient's past medical history of a congenital diaphragmatic hernia or other congenital malformation of the diaphragm that has been surgically or medically corrected. It signifies that the condition is no longer active but has a lasting impact on the patient's health record.

Use this code when documenting follow-up care for individuals who previously underwent treatment for a congenital diaphragmatic defect. It is appropriate for patients presenting for routine check-ups, monitoring for long-term complications, or evaluation of unrelated conditions, where the history of the corrected diaphragmatic anomaly is relevant to their overall health status.

• Always sequence this code as a secondary diagnosis, as it represents a historical condition, not an active problem requiring current treatment.
• Ensure documentation clearly states the diaphragmatic anomaly was congenital and has been corrected.
• Do not use this code for active, uncorrected congenital diaphragmatic hernias or malformations; instead, use codes from category Q79.0.
