S72.24XA vs S72.24XF

S72.24XA (Nondisplaced subtrochanteric fracture of right femur, initial encounter for closed fracture) compared with S72.24XF (Nondisplaced subtrochanteric fracture of right femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing), from the official CMS tabular data. S72.24XA and S72.24XF code the same injury at a different phase of treatment. MedCoder-derived

Encounter relationship

S72.24XA
Initial encounter
Nondisplaced subtrochanteric fracture of right femur, initial encounter for closed fracture
S72.24XF
Subsequent encounter
Nondisplaced subtrochanteric fracture of right femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Same underlying diagnosis, different encounter phase.

The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.

Can these codes be reported together?

Same injury, other encounter phase. S72.24XA and S72.24XF code the same injury at a different phase of treatment, set by the 7th character.

The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
