About coding eating habits inadequate
The ICD-10-CM code for eating habits inadequate is Z72.4 (Inappropriate diet and eating habits).
Within Z72 (problems related to lifestyle), Z72.4 is specifically for inappropriate diet and eating habits. Related codes cover tobacco use (Z72.0), lack of physical exercise (Z72.3), high risk sexual behavior (Z72.5), gambling and betting (Z72.6), other problems related to lifestyle (Z72.8) and problem related to lifestyle, unspecified (Z72.9).
Don't report Z72.4 together with the conditions in its Excludes1 note: behavioral eating disorders of infancy or childhood (F98.2.-F98.3), eating disorders (F50.-), lack of adequate food (Z59.48) and malnutrition and other nutritional deficiencies (E40-E64).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
