[Review and update of the SENPE-SEDOM-SEEN consensus document on the coding of hospital malnutrition]

The concept of "disease related malnutrition" (DRM) is far from the concept of malnutrition classically diagnosed in public health, which is determined by socio-demographic factors. In 2008, the Spanish Society of Clinical Nutrition and Metabolism (SENPE) and the Spanish Society of Medical Documentation (SEDOM) published a consensus defining more precisely the types of malnutrition seen in hospitals and their corresponding coding. Changes in the International Classification of Diseases (ICD) and the evolution of clinical information have made it necessary to revise and update this consensus in order to establish new criteria to guide the recording and coding of diagnoses of malnutrition in the field of hospital care, thus facilitating the work of both clinicians and coders and improving the visibility of DRE, by adapting from the clinical diagnoses of undernutrition based on the GLIM criteria (Global Leadership Initiative on Malnutrition) proposed by the scientific societies to the current codes proposed by ICD-10-ES. This document reflects the new consensus of the SENPE, SEEN and SEDOM societies, and refers to the coding of DRE, other nutritional diagnoses and medical nutritional treatment procedures, sets out the coding criteria and proposes suggestions to improve coding at the hospital level.
