S22.49XK (Multiple fractures of ribs, unspecified side, subsequent encounter for fracture with nonunion) compared with T20 (Burn and corrosion of head, face, and neck), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Distinct conditions — both may be reported.
“burns and corrosions (T20-T32)”
An Excludes2 note means the excluded condition is not part of the code above it, but a patient can have both. Report both when both are documented.
