S62.513A vs S62.513G

S62.513A (Displaced fracture of proximal phalanx of unspecified thumb, initial encounter for closed fracture) compared with S62.513G (Displaced fracture of proximal phalanx of unspecified thumb, subsequent encounter for fracture with delayed healing), from the official CMS tabular data. S62.513A and S62.513G code the same injury at a different phase of treatment. MedCoder-derived

Encounter relationship

S62.513A
Initial encounter
Displaced fracture of proximal phalanx of unspecified thumb, initial encounter for closed fracture
S62.513G
Subsequent encounter
Displaced fracture of proximal phalanx of unspecified thumb, 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. S62.513A and S62.513G 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.
