S05.20XA

Initial encounter

Ocular laceration and rupture with prolapse or loss of intraocular tissue, unspecified eye, initial encounter

↔

S05.20XD

Subsequent encounter

Ocular laceration and rupture with prolapse or loss of intraocular tissue, unspecified eye, 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. S05.20XA and S05.20XD 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.
