About coding health insurance coverage no
The ICD-10-CM code for health insurance coverage no is Z59.71 (Insufficient health insurance coverage).
Within Z59.7 (insufficient social insurance and welfare support), Z59.71 is specifically for insufficient health insurance coverage. Related codes cover welfare support (Z59.72).
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.
