About coding dyes contact
The ICD-10-CM code for dyes contact is Z77.098 (Contact with and (suspected) exposure to other hazardous, chiefly nonmedicinal, chemicals).
Within Z77.09, choose Z77.098 (other hazardous, chiefly nonmedicinal, chemicals) only when documentation doesn't support a more specific option: asbestos (Z77.090).
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.
