About coding lung laceration
The ICD-10-CM code for lung laceration is S27.339 (Laceration of lung, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S27.339.
Within S27.33, choose S27.339 (unspecified) only when documentation doesn't support a more specific option: unilateral (S27.331) and bilateral (S27.332).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
