T20.219 ICD-10-CM Code: Burn of second degree of unspecified ear [any part, except ear drum]

T20.219 is the ICD-10-CM diagnosis code for burn of second degree of unspecified ear [any part, except ear drum]. T20.219 sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering burns and corrosions of external body surface, specified by site (t20-t25).

Header codes like T20.219 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at T20.219's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
