S72.126C Nondisplaced fracture of lesser trochanter of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC
Billable ICD-10-CM code, FY2026.
Built from S72.126 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
The appropriate 7th character is to be added to all codes from category S72
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
7th character required
A — initial encounter for closed fracture
B — initial encounter for open fracture type I or II

F — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
G — subsequent encounter for closed fracture with delayed healing
H — subsequent encounter for open fracture type I or II with delayed healing
J — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
K — subsequent encounter for closed fracture with nonunion
M — subsequent encounter for open fracture type I or II with nonunion
N — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
P — subsequent encounter for closed fracture with malunion
Q — subsequent encounter for open fracture type I or II with malunion
R — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
S — sequela
