S14.145A

Initial encounter

Brown-Séquard syndrome at C5 level of cervical spinal cord, initial encounter

↔

S14.145D

Subsequent encounter

Brown-Séquard syndrome at C5 level of cervical spinal cord, 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. S14.145A and S14.145D 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.
