About coding subcutaneous traumatic emphysema
The ICD-10-CM code for subcutaneous traumatic emphysema is T79.7 (Traumatic subcutaneous emphysema). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T79.7.
Within T79 (certain early complications of trauma, not elsewhere classified), T79.7 is specifically for traumatic subcutaneous emphysema. Related codes cover air embolism (traumatic) (T79.0), fat embolism (traumatic) (T79.1), traumatic secondary and recurrent hemorrhage and seroma (T79.2), traumatic shock (T79.4), traumatic anuria (T79.5), traumatic ischemia of muscle (T79.6), other early complications of trauma (T79.8), unspecified early complication of trauma (T79.9) and 1 more.
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
The conditions in its Excludes2 note aren't part of T79.7, but may be coded alongside it if the patient has both: emphysema NOS (J43) and emphysema (subcutaneous) resulting from a procedure (T81.82).
