Other lactose intolerance
ICD-10 E73.8 is a billable code used to indicate a diagnosis of other lactose intolerance.
Other lactose intolerance refers to a condition where individuals experience gastrointestinal symptoms due to the inability to properly digest lactose, a sugar found in milk and dairy products. This condition can arise from various metabolic disorders, including enzyme deficiencies that affect lactase production, leading to symptoms such as bloating, diarrhea, and abdominal pain after lactose consumption. Unlike primary lactose intolerance, which is genetically determined and common in certain populations, other lactose intolerance may be secondary to other medical conditions, such as gastrointestinal infections, inflammatory bowel disease, or certain genetic metabolic disorders. The diagnosis often involves clinical evaluation, dietary history, and possibly hydrogen breath tests to confirm lactase deficiency. Management typically includes dietary modifications to limit lactose intake and may involve lactase enzyme supplements to alleviate symptoms. Understanding the underlying cause of lactose intolerance is crucial for effective treatment and patient education.
Detailed patient history, symptom assessment, and results from diagnostic tests such as hydrogen breath tests.
Patients presenting with gastrointestinal symptoms after dairy consumption, requiring evaluation for lactose intolerance.
Ensure that all relevant gastrointestinal conditions are ruled out before diagnosing lactose intolerance.
Growth charts, dietary history, and family history of lactose intolerance or related metabolic disorders.
Children with recurrent abdominal pain or diarrhea after consuming dairy products.
Consider the developmental stage of the child and the potential for transient lactose intolerance following gastrointestinal infections.
Used to confirm lactose intolerance diagnosis.
Document the test results and patient symptoms.
Gastroenterologists should ensure comprehensive evaluation of symptoms.
Primary lactose intolerance is a genetic condition where lactase production decreases with age, while secondary lactose intolerance occurs due to damage to the intestine from diseases or infections.
