2025 ICD-10-CM code K29.9
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the digestive system - Gastritis and duodenitis Diseases of the digestive system Feed
Gastroduodenitis, unspecified: Inflammation of the stomach and duodenum without further specification.
Modifiers may be applicable depending on the circumstances of the encounter, but this code itself doesn't inherently require modifiers.
Medical necessity for K29.9 would be established through the presence of clinically significant symptoms suggestive of gastroduodenitis, confirmed via relevant diagnostic testing. The documentation should justify the need for medical intervention or monitoring based on the severity of the condition.
The clinical responsibility for diagnosing and managing gastroduodenitis typically falls upon gastroenterologists or primary care physicians.Further specialist involvement may be necessary depending on the complexity and underlying cause.
In simple words: This code means there's inflammation in both your stomach and the first part of your small intestine (duodenum).Doctors use this code when they know there's inflammation but don't know the exact cause or type.
K29.9, Gastroduodenitis, unspecified, refers to the inflammation of both the stomach (gastritis) and the duodenum (duodenitis) without specifying the cause, type, or severity.This code is used when the clinical picture suggests inflammation in both organs but further details are lacking for more precise coding.The lack of specificity necessitates further investigation to determine the underlying cause and potentially allow for more precise coding in future encounters.
Example 1: A patient presents with epigastric pain, nausea, vomiting, and heartburn.Endoscopy reveals mild inflammation in both the stomach and duodenum.Further investigations such as H. pylori testing are pending.K29.9 is used initially., A patient with a history of NSAID use reports persistent abdominal discomfort.Upper endoscopy reveals diffuse mild gastritis and duodenitis.The cause is suspected to be NSAID-induced but not definitively confirmed. K29.9 is appropriate., A patient undergoing routine check-up has elevated inflammatory markers.Further investigation using endoscopy reveals mild non-specific gastroduodenitis. The underlying cause remains unknown.K29.9 is used.
Complete history and physical examination, including detailed description of symptoms (e.g., location, duration, character of abdominal pain, nausea, vomiting, dyspepsia, etc.).Results of relevant investigations like endoscopy with biopsies, H. pylori testing, blood tests (e.g., inflammatory markers), and imaging studies should be documented.
** In outpatient settings, append an appropriate diagnostic confidence indicator (A, G, V, or Z) to the code as per local guidelines.
