In Burns and corrosions confined to eye and internal organs (T26-T28), chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes
24 billable codes under T27: 8 are a CC; none map to an HCC.A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment.

- Section I.C.19.d Coding of Burns and Corrosions (page 80), covers T27
Sequence the highest degree burn first and code each site separately, using the highest degree for one site. Code non-healing burns as acute, add codes for infection, and add an external cause code for source, intent, and place.

About the condition

Burns
A burn is damage to your body's tissues caused by heat, chemicals, electricity, sunlight, or radiation. Scalds from hot liquids and steam, building fires and flammable liquids and gases are the most common causes of burns. Another kind is an inhalation injury, caused by breathing smoke.
