Food Protein-Induced Enterocolitis Syndrome (FPIES) is a non-IgE mediated gastrointestinal food allergy. The ICD10 code for FPIES is K52.21. Unfortunately, there is no specific ICD9 code for FPIES as it was replaced by ICD10. FPIES is characterized by severe vomiting, diarrhea, and dehydration. It typically affects infants and young children. Prompt recognition and avoidance of trigger foods are crucial in managing FPIES.
Food Protein-Induced Enterocolitis Syndrome (FPIES) is a rare non-IgE-mediated gastrointestinal food allergy that primarily affects infants and young children. It is characterized by delayed onset symptoms, typically occurring within hours after ingestion of the offending food protein. FPIES is a complex condition that involves inflammation of the gastrointestinal tract, leading to vomiting, diarrhea, and occasionally, dehydration.
In terms of medical coding, the International Classification of Diseases, 10th Revision (ICD-10) provides a specific code for FPIES. The appropriate ICD-10 code for Food Protein-Induced Enterocolitis Syndrome is K52.21. This code falls under the category of "Other noninfective gastroenteritis and colitis," specifically indicating an allergic or eosinophilic gastroenteritis. The code K52.21 allows healthcare providers and researchers to accurately identify and track cases of FPIES, aiding in the analysis of its prevalence and impact on affected individuals.
In contrast, the International Classification of Diseases, 9th Revision (ICD-9) does not have a specific code for FPIES. However, healthcare providers may have used a more general code to classify cases of non-IgE-mediated food allergies, such as 558.9 - Other and unspecified noninfectious gastroenteritis and colitis. This code does not specifically indicate FPIES but may have been utilized to capture similar clinical presentations.
It is important to note that the transition from ICD-9 to ICD-10 occurred on October 1, 2015, making ICD-10 the current coding system used in most countries. The specificity and granularity of ICD-10 codes allow for more accurate documentation and classification of various medical conditions, including FPIES. This, in turn, facilitates improved research, healthcare planning, and reimbursement processes.
