S59.201A vs S59.201G

S59.201A (Unspecified physeal fracture of lower end of radius, right arm, initial encounter for closed fracture) compared with S59.201G (Unspecified physeal fracture of lower end of radius, right arm, subsequent encounter for fracture with delayed healing), from the official CMS tabular data. S59.201A and S59.201G code the same injury at a different phase of treatment.

Encounter relationship

S59.201A
Initial encounter
Unspecified physeal fracture of lower end of radius, right arm, initial encounter for closed fracture
S59.201G
Subsequent encounter
Unspecified physeal fracture of lower end of radius, right arm, subsequent encounter for fracture with delayed healing

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. S59.201A and S59.201G 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.
