T81.320A vs T81.320D
T81.320A (Disruption or dehiscence of gastrointestinal tract anastomosis, repair, or closure, initial encounter) compared with T81.320D (Disruption or dehiscence of gastrointestinal tract anastomosis, repair, or closure, subsequent encounter), from the official CMS tabular data. T81.320A and T81.320D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T81.320A and T81.320D 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.
