Encounter relationship

S25.592A
Initial encounter
Other specified injury of intercostal blood vessels, left side, initial encounter
↔
S25.592D
Subsequent encounter
Other specified injury of intercostal blood vessels, left side, subsequent encounter

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. S25.592A and S25.592D 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.
