Encounter relationship

S02.11DA

Initial encounter

Type II occipital condyle fracture, left side, initial encounter for closed fracture

↔

S02.11DG

Subsequent encounter

Type II occipital condyle fracture, left side, subsequent encounter for fracture with delayed 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. S02.11DA and S02.11DG 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.
