compared with
S92.406K (Nondisplaced unspecified fracture of unspecified great toe, subsequent encounter for fracture with nonunion),

Nondisplaced unspecified fracture of unspecified great toe, subsequent encounter for fracture with nonunion
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.

Same injury, other encounter phase. S92.406A and S92.406K 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.
