Gastroparesis

This code identifies gastroparesis, a chronic disorder characterized by delayed gastric emptying in the absence of mechanical obstruction. It results from impaired motility of the stomach muscles, preventing food from moving into the small intestine normally.

Assign this code when documentation explicitly states a diagnosis of gastroparesis. Common clinical scenarios include idiopathic gastroparesis or gastroparesis secondary to conditions like diabetes (diabetic gastroparesis, which would be coded separately with an additional code). Supporting documentation often includes gastric emptying studies confirming delayed emptying.

• Do not use this code if a mechanical obstruction is present; instead, code the specific obstruction.
• For diabetic gastroparesis, sequence the diabetes code first, followed by this code.
• Ensure documentation specifies "gastroparesis" and not just general dyspepsia or nausea.
