CP.PP.145

Malnutrition

Acute care hospitalizations for malnutrition require the most appropriate and most specific level of diagnosis coding. The medical record documentation supporting the diagnosis should be clearly documented by the physician or a licensed independent practitioner.

The cost difference between a Diagnosis Related Group (DRG) billed with malnutrition as a major complication or comorbidity (MCC) (in a position other than as the primary diagnosis code position) and a DRG billed without malnutrition as an MCC (in a position other than as the primary diagnosis code position) will be denied reimbursement unless meeting the documentation requirements described in this policy.

The purpose of this policy is to support a retrospective review of inpatient claims billed with the diagnosis of malnutrition.
