Gastroparesis

This code represents gastroparesis, a chronic disorder characterized by delayed gastric emptying in the absence of mechanical obstruction. It results from impaired nerve function to the stomach muscles, leading to symptoms like nausea, vomiting, early satiety, and abdominal bloating.

Use this code when documentation clearly indicates a diagnosis of gastroparesis, often supported by gastric emptying studies demonstrating delayed emptying. It is appropriate for both idiopathic gastroparesis and gastroparesis secondary to conditions like diabetes mellitus.

• Always look for documentation of diagnostic testing, such as a gastric emptying scintigraphy, to support the diagnosis.
• Distinguish from functional dyspepsia, which may present with similar symptoms but lacks objective evidence of delayed gastric emptying.
• When gastroparesis is secondary to another condition (e.g., diabetic gastroparesis), code the underlying condition first, followed by this code.
