S62.509A vs S62.509D
S62.509A (Fracture of unspecified phalanx of unspecified thumb, initial encounter for closed fracture) compared with S62.509D (Fracture of unspecified phalanx of unspecified thumb, subsequent encounter for fracture with routine healing), from the official CMS tabular data. S62.509A and S62.509D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S62.509A and S62.509D 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.
