About coding Insufflation
The ICD-10-CM code for Insufflation is Z31.41 (Encounter for fertility testing).
Within Z31.4 (encounter for procreative investigation and testing), Z31.41 is specifically for encounter for fertility testing. Related codes cover aftercare following sterilization reversal (Z31.42), 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.
