Postproc intestinal obst, unsp as to partial versus complete

This code describes an obstruction of the intestines that occurs as a complication following a surgical or other medical procedure. It indicates that the specific nature of the obstruction (whether it's partially or completely blocking the intestine) has not been documented.

Use this code when documentation clearly states a patient has developed an intestinal obstruction post-procedure, and the physician has not specified if the obstruction is partial or complete. This applies to obstructions arising after any type of surgical intervention, endoscopy, or other invasive procedure.

• Do not use this code if the documentation specifies "partial" (K91.31) or "complete" (K91.32) obstruction; query the provider if unclear.
• Always sequence this code after the code for the underlying procedure or condition that led to the obstruction, if applicable.
• Distinguish from non-postprocedural intestinal obstructions (K56.x series) which are not complications of a procedure.
