Encounter relationship

T26.30XA

Initial encounter

Burns of other specified parts of unspecified eye and adnexa, initial encounter

↔

T26.30XD

Subsequent encounter

Burns of other specified parts of unspecified eye and adnexa, 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. T26.30XA and T26.30XD 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.
