About coding food insecurity
The ICD-10-CM code for food insecurity is Z59.41 (Food insecurity).
Within Z59.4 (lack of adequate food), Z59.41 is specifically for food insecurity. Related codes cover other specified lack of adequate food (Z59.48).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
