About coding asbestos exposure
The ICD-10-CM code for asbestos exposure is Z77.090 (Contact with and (suspected) exposure to asbestos).
Within Z77.09 (contact with and (suspected) exposure to other hazardous, chiefly nonmedicinal, chemicals), Z77.090 is specifically for contact with and (suspected) exposure to asbestos. Related codes cover other hazardous, chiefly nonmedicinal, chemicals (Z77.098).
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.
