About coding leg lower fracture

The ICD-10-CM code for leg lower fracture is S82.9 (Unspecified fracture of lower leg). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S82.9.

Within S82, choose S82.9 (Unspecified fracture of lower leg) only when documentation doesn't support a more specific option: fracture of patella (S82.0), fracture of upper end of tibia (S82.1), fracture of shaft of tibia (S82.2), fracture of lower end of tibia (S82.3), fracture of shaft of fibula (S82.4), fracture of medial malleolus (S82.5), fracture of lateral malleolus (S82.6) and other fractures of lower leg (S82.8).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture type I or II, C for initial encounter for open fracture type IIIA, IIIB, or IIIC, D for subsequent encounter for closed fracture with routine healing, E for subsequent encounter for open fracture type I or II with routine healing, F for subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing and 10 more. 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.
