S36.592A vs S36.592D
S36.592A (Other injury of descending [left] colon, initial encounter) compared with S36.592D (Other injury of descending [left] colon, subsequent encounter), from the official CMS tabular data. S36.592A and S36.592D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S36.592A and S36.592D 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.
