About T28.419D
T28.419D is the ICD-10-CM diagnosis code for burn of unspecified ear drum, subsequent encounter. It belongs to category T28 (burn and corrosion of other internal organs), block T26-T28 (burns and corrosions confined to eye and internal organs) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.
Use an additional code for: external cause code to identify the source and intent of the burn (X00-X19, X75-X77, X96-X98) and external cause code to identify place (Y92).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 949 (Aftercare with CC/MCC, relative weight 1.123) and DRG 950 (Aftercare without CC/MCC, relative weight 0.7664), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V58.89 (other specified aftercare).
