Ascariasis with other complications

This code signifies an infection with the roundworm Ascaris lumbricoides that has led to complications beyond the typical gastrointestinal symptoms, but which are not specifically classified elsewhere. These complications can involve various organ systems due to larval migration or adult worm burden.

Use this code when documentation specifies ascariasis with complications such as biliary obstruction, pancreatitis, appendicitis, intestinal perforation, or other organ system involvement, and a more specific complication code (e.g., B77.0 for intestinal obstruction) is not applicable. The medical record must clearly describe the ascariasis and the associated "other" complication.

• Do not use this code if the complication is specifically listed under another B77 subcategory (e.g., B77.0 for intestinal obstruction).
• Always sequence the ascariasis code first, followed by codes for any specific manifestations or complications, if applicable and not already inherent in the B77.x code.
• Ensure the documentation explicitly states "ascariasis with other complications" or details a complication not otherwise classified for ascariasis.
