Acquired absence of stomach [part of]

This code signifies the complete or partial removal of the stomach, which is an acquired condition rather than a congenital anomaly. It reflects the anatomical absence of gastric tissue due to surgical intervention or other medical necessity.

This code is appropriate for patients who have undergone a gastrectomy (total or partial) due to conditions such as gastric cancer, severe peptic ulcer disease, or morbid obesity. It should be used to document the patient's current anatomical status following such procedures.

• Always specify the extent of stomach removal if known (e.g., total vs. partial gastrectomy) using additional codes if available and supported by documentation.
• Do not use this code for congenital absence of the stomach; a different code would be required for that rare condition.
• This code is typically a secondary diagnosis, reflecting the patient's altered anatomy, while the primary diagnosis would be the reason for the original surgery or the current condition being treated.
