S62.643A vs S62.643D
S62.643A (Nondisplaced fracture of proximal phalanx of left middle finger, initial encounter for closed fracture) compared with S62.643D (Nondisplaced fracture of proximal phalanx of left middle finger, subsequent encounter for fracture with routine healing), from the official CMS tabular data. S62.643A and S62.643D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S62.643A and S62.643D 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.
