S72.463C Displaced supracondylar fracture with intracondylar extension of lower end of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC
Billable ICD-10-CM code, FY2026.
Built from S72.463 with 7th character C (initial encounter for open fracture type IIIA, IIIB, or IIIC).
Applies from S72 Fracture of femur
Excludes1 (never code together)
traumatic amputation of hip and thigh (S78.-)
Excludes2 (not included here)
fracture of lower leg and ankle (S82.-)
fracture of foot (S92.-)
periprosthetic fracture of prosthetic implant of hip (M97.0-)
7th character note

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
