These are the routes through the Alphabetic Index that lead to T81.320. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Dehiscence › closure of › gastrointestinal tract anastomosis, repair, or closure (of)
  • Disruption › closure of › gastrointestinal tract anastomosis, repair, or closure (of)

Excludes1 — never code together — inherited from T81.3

The conditions below can never be reported together with T81.320 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • breakdown (mechanical) of permanent sutures (T85.612)
  • displacement of permanent sutures (T85.622)
  • disruption of cesarean delivery wound (O90.0)
  • disruption of perineal obstetric wound (O90.1)
  • mechanical complication of permanent sutures NEC (T85.692)

Use additional code — inherited from Chapter 19

Report an additional code alongside T81.320 to fully describe the condition. T81.320 is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Use additional code — inherited from T80-T88

Report an additional code alongside T81.320 to fully describe the condition. T81.320 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code(s) to identify the specified condition resulting from the complication
  • code to identify devices involved and details of circumstances (Y62-Y82)
