Initial encounter

Traumatic hemorrhage of right cerebrum with loss of consciousness of 6 hours to 24 hours, initial encounter

↔

S06.344S

Sequela

Traumatic hemorrhage of right cerebrum with loss of consciousness of 6 hours to 24 hours, sequela

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. S06.344A and S06.344S 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.
