S37.042A vs S37.042D
S37.042A (Minor laceration of left kidney, initial encounter) compared with S37.042D (Minor laceration of left kidney, subsequent encounter), from the official CMS tabular data. S37.042A and S37.042D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S37.042A and S37.042D 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.
