About coding knee laceration
The ICD-10-CM code for knee laceration is S81.01 (Laceration without foreign body of knee). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S81.01.
Within S81.0, choose S81.01 (Laceration without foreign body of knee) only when documentation doesn't support a more specific option: unspecified open wound of knee (S81.00), laceration with foreign body of knee (S81.02), puncture wound without foreign body of knee (S81.03), puncture wound with foreign body of knee (S81.04) and open bite of knee (S81.05).
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.
