About coding aftercare vasoplasty
The ICD-10-CM code for aftercare vasoplasty is Z31.42 (Aftercare following sterilization reversal).
Within Z31.4 (encounter for procreative investigation and testing), Z31.42 is specifically for aftercare following sterilization reversal. Related codes cover encounter for fertility testing (Z31.41), encounter for genetic testing of female for procreative management (Z31.43), encounter for genetic testing of male for procreative management (Z31.44) and encounter for other procreative investigation and testing (Z31.49).
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.
