579.3
ICD-9-CMThis code signifies malabsorption that develops as a direct consequence of a surgical intervention, particularly those involving the gastrointestinal tract. It encompasses various forms of impaired nutrient absorption that are not otherwise specified or are considered "other" post-surgical causes.
Use this code when documentation clearly links a patient's malabsorption syndrome to a prior surgical procedure, such as bariatric surgery, bowel resection, or gastrectomy. Supporting documentation should include physician notes detailing the onset of malabsorption post-surgery and ruling out other primary causes.
