About coding Antiplatelet long-term drug therapy

The ICD-10-CM code for Antiplatelet long-term drug therapy is Z79.02 (Long term (current) use of antithrombotics/antiplatelets).

Within Z79.0 (long term (current) use of anticoagulants and antithrombotics/antiplatelets), Z79.02 is specifically for long term (current) use of antithrombotics/antiplatelets. Related codes cover anticoagulants (Z79.01).

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 949 (Aftercare with CC/MCC, relative weight 1.123) and DRG 950 (Aftercare without CC/MCC, relative weight 0.7664), 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.
