S36.598A vs S36.598D
S36.598A (Other injury of other part of colon, initial encounter) compared with S36.598D (Other injury of other part of colon, subsequent encounter), from the official CMS tabular data. S36.598A and S36.598D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S36.598A and S36.598D 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.
