S02.129A vs S02.129D

S02.129A (Fracture of orbital roof, unspecified side, initial encounter for closed fracture) compared with S02.129D (Fracture of orbital roof, unspecified side, subsequent encounter for fracture with routine healing), from the official CMS tabular data. S02.129A and S02.129D code the same injury at a different phase of treatment.

Encounter relationship

S02.129A

Initial encounter

Fracture of orbital roof, unspecified side, initial encounter for closed fracture

↔

S02.129D

Subsequent encounter

Fracture of orbital roof, unspecified side, subsequent encounter for fracture 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. S02.129A and S02.129D 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.
