Encounter relationship

S76.301A
Initial encounter
Unspecified injury of muscle, fascia and tendon of the posterior muscle group at thigh level, right thigh, initial encounter
S76.301D
Subsequent encounter
Unspecified injury of muscle, fascia and tendon of the posterior muscle group at thigh level, right thigh, 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. S76.301A and S76.301D 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.
