Acute gastritis without bleeding

This code signifies an acute inflammatory process of the gastric mucosa, characterized by sudden onset and typically short duration. It involves irritation or erosion of the stomach lining, but without any evidence of hemorrhage. Patients often present with symptoms such as epigastric pain, nausea, vomiting, and dyspepsia.

Apply this code when documentation clearly indicates acute inflammation of the stomach lining without any mention of bleeding. This is appropriate for cases of acute gastritis caused by factors like NSAID use, alcohol consumption, stress, or bacterial/viral infections, where endoscopic findings or clinical assessment confirm the absence of hemorrhage.

• Ensure documentation explicitly states "without bleeding" or clearly lacks any indication of hemorrhage (e.g., hematemesis, melena, positive stool occult blood).
• Differentiate from K29.01 (Acute gastritis with bleeding) based on the presence or absence of hemorrhage.
• Consider sequencing with codes for underlying causes (e.g., adverse effect of drug, alcohol abuse) if applicable and documented.
