About coding consanguinity counseling
The ICD-10-CM code for consanguinity counseling is Z71.89 (Other specified counseling).
Within Z71.8, choose Z71.89 (Other specified counseling) only when documentation doesn't support a more specific option: Spiritual or religious counseling (Z71.81), exercise counseling (Z71.82), encounter for nonprocreative genetic counseling (Z71.83), encounter for health counseling related to travel (Z71.84), encounter for immunization safety counseling (Z71.85), encounter for pediatric-to-adult transition counseling (Z71.87) and encounter for counseling for socioeconomic factors (Z71.88).
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.
