S62.305A vs S62.305K
S62.305A (Unspecified fracture of fourth metacarpal bone, left hand, initial encounter for closed fracture) compared with S62.305K (Unspecified fracture of fourth metacarpal bone, left hand, subsequent encounter for fracture with nonunion), from the official CMS tabular data. S62.305A and S62.305K code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S62.305A and S62.305K 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.
