S62.349A vs S62.349K
S62.349A (Nondisplaced fracture of base of unspecified metacarpal bone, initial encounter for closed fracture) compared with S62.349K (Nondisplaced fracture of base of unspecified metacarpal bone, subsequent encounter for fracture with nonunion), from the official CMS tabular data. S62.349A and S62.349K code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S62.349A and S62.349K 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.
