About coding breast laceration
The ICD-10-CM code for breast laceration is S21.01 (Laceration without foreign body of breast). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S21.01.
Within S21.0, choose S21.01 (Laceration without foreign body of breast) only when documentation doesn't support a more specific option: unspecified open wound of breast (S21.00), laceration with foreign body of breast (S21.02), puncture wound without foreign body of breast (S21.03), puncture wound with foreign body of breast (S21.04) and open bite of breast (S21.05).
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.
