Intestinal obstruction varies in severity, from partial or intermittent obstruction that usually resolves without intervention, to complete obstruction that requires surgery and may lead to intestinal gangrene and perforation. Coders should assign an ICD-10-CM code from subcategory K91.3- (postprocedural intestinal obstruction) when the documentation indicates the obstruction is a complication following a procedure, based on whether the obstruction is partial, complete, or unspecified.
