Long Title
S82.856A
-
Nondisplaced trimalleolar fracture of unspecified lower leg initial encounter for closed fracture
Notes
-
A fracture not indicated as displaced or nondisplaced should be coded to displaced
-
A fracture not indicated as open or closed should be coded to closed
-
The open fracture designations are based on the Gustilo open fracture classification
-
Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
-
The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.
