Partial intestinal obstruction, unspecified as to cause

This code represents a blockage within the small or large intestine that is not complete, allowing some passage of contents. The underlying reason for this partial obstruction is not identified or documented. It indicates a functional or mechanical impediment to normal intestinal flow.

This code is appropriate when documentation clearly states "partial intestinal obstruction" but provides no further information regarding the etiology (e.g., adhesions, hernia, tumor). It should be used when the physician explicitly states the cause is unknown or unspecified.

• Do not use this code if the cause of the partial obstruction is known and documented (e.g., adhesions, volvulus).
• Always query the provider for a more specific diagnosis if the cause is suspected but not explicitly stated.
• Distinguish from complete intestinal obstruction, which has different code assignments.
