Personal history of (corrected) congenital malform of ear

This code indicates a patient's past medical history of a congenital malformation of the ear that has been surgically or medically corrected. It signifies that the structural anomaly present at birth is no longer an active problem, but its prior existence is clinically relevant. This includes conditions like microtia, anotia, or other structural defects of the external, middle, or inner ear that have undergone intervention.

Use this code when documenting a patient's history of a congenital ear malformation that has been successfully treated, and the patient is no longer actively receiving care for the malformation itself. This is appropriate for follow-up visits where the primary reason for the encounter is unrelated to the original malformation, but the history is pertinent for comprehensive patient care. It is also used when the history impacts current treatment decisions or risk assessments.

• Always sequence this code as a secondary diagnosis, as it represents a historical condition, not a current active problem.
• Ensure the documentation clearly states that the congenital malformation has been "corrected" or "repaired" to justify the use of this specific history code.
• Do not use this code if the congenital malformation is still active, uncorrected, or if the patient is currently receiving treatment for the malformation itself; in such cases, an active congenital anomaly code would be more appropriate.
