`S82.845D` Nondisplaced bimalleolar fracture of left lower leg, subsequent encounter for closed fracture with routine healing

Billable ICD-10-CM code, FY2026.

Built from S82.845 with 7th character D (subsequent encounter for closed fracture with routine healing).

fracture of foot, except ankle (S92.-)
periprosthetic fracture around internal prosthetic ankle joint (M97.2)
periprosthetic fracture around internal prosthetic implant of knee joint (M97.1-)

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

A — initial encounter for closed fracture
B — initial encounter for open fracture type I or II
C — initial encounter for open fracture type IIIA, IIIB, or IIIC
D — subsequent encounter for closed fracture with routine healing
E — subsequent encounter for open fracture type I or II with routine healing
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
