Unilateral inguinal hernia, w obst, w/o gangrene, recurrent

This code signifies a recurrent inguinal hernia located on one side of the body that has become obstructed. Obstruction implies a blockage of the bowel within the hernia sac, but without evidence of tissue death (gangrene). This condition typically presents with acute pain, nausea, vomiting, and constipation.

Apply this code when documentation clearly indicates a previously repaired inguinal hernia has recurred, is now unilateral, and is causing obstructive symptoms such as bowel obstruction. The physician's notes must explicitly state "with obstruction" and confirm the absence of gangrene.

• Ensure the documentation specifies "recurrent" to differentiate from an initial hernia.
• Verify laterality (unilateral) is documented; if bilateral, a different code would be appropriate.
• Confirm the absence of gangrene; if gangrene is present, a more severe code (e.g., K40.41) should be used.
