T32Not billable, use a more specific code below
Corrosions 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 T32: 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.

- Section I.C.19.d Coding of Burns and Corrosions (page 80), covers T32
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
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.
