2025 ICD-10-CM code K29
Gastritis and duodenitis.
Medical necessity for K29 is established by the presence of signs, symptoms, or diagnostic findings consistent with gastritis and/or duodenitis. Documentation should support the need for diagnostic testing and treatment to manage the condition and prevent complications.For example, if a patient presents with persistent abdominal pain, nausea, and vomiting, an endoscopy to evaluate for gastritis and/or duodenitis would be medically necessary.
Clinicians responsible for diagnosing and managing gastritis and duodenitis include gastroenterologists, primary care physicians, and internists.Responsibilities include taking a detailed patient history, performing a physical exam, ordering appropriate diagnostic tests (such as endoscopy, biopsy, and blood tests), and developing a treatment plan.Treatment may involve medications to reduce acid production, antibiotics to eradicate H. pylori infection, lifestyle modifications (e.g., dietary changes, avoiding alcohol and NSAIDs), and managing any underlying medical conditions.
In simple words: This code refers to inflammation of the stomach (gastritis) and/or the first part of the small intestine (duodenitis).
Gastritis and duodenitis are inflammatory conditions affecting the lining of the stomach (gastritis) and the duodenum (duodenitis), the first part of the small intestine.They can occur together or separately and have various causes, including infections (such as Helicobacter pylori), nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, and autoimmune disorders.
Example 1: A 45-year-old patient presents with upper abdominal pain, nausea, and vomiting.Endoscopy reveals inflammation of the stomach lining, consistent with gastritis.The physician codes this as K29., A 28-year-old patient with a history of heavy alcohol use complains of burning pain in the upper abdomen and frequent indigestion.A diagnosis of alcoholic gastritis is made, coded as K29.2., A 60-year-old patient undergoes a routine upper endoscopy, which shows chronic inflammation and thinning of the stomach lining, indicative of chronic atrophic gastritis. This is coded as K29.4.
Documentation should include details of the patient's symptoms, medical history, relevant physical exam findings, diagnostic test results (e.g., endoscopy, biopsy, H. pylori testing), and treatment plan. The specific type of gastritis or duodenitis, if known, should be documented (e.g., acute, chronic, erosive, etc.). Any associated complications, such as bleeding or ulcers, should also be noted.
