S35.239A vs S35.239S

S35.239A (Unspecified injury of inferior mesenteric artery, initial encounter) compared with S35.239S (Unspecified injury of inferior mesenteric artery, sequela), from the official CMS tabular data. S35.239A and S35.239S code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. S35.239A and S35.239S 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.
