Burns classified according to extent of body surface involved
In Burns and corrosions of multiple and unspecified body regions (T30-T32), chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes
55 billable codes under T31: 44 are an MCC, 10 are a CC; 45 map to HCC 385 (Severe Skin Burn).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
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.
