Acquired partial absence of pancreas

This code signifies a condition where a portion of the pancreas is missing due to a non-congenital cause. This partial absence can result in impaired exocrine and/or endocrine pancreatic function, affecting digestion and blood sugar regulation.

Apply this code for patients who have undergone a partial pancreatectomy, such as a Whipple procedure or distal pancreatectomy, for conditions like tumors, cysts, or pancreatitis. It is also appropriate for cases of pancreatic tissue loss due to trauma or severe necrotizing pancreatitis.

• Always specify the underlying reason for the acquired partial absence with an additional diagnosis code.
• Distinguish carefully between acquired and congenital absence; congenital cases use codes from the Q45 series.
• Do not use this code for functional impairment without actual tissue loss.
