About coding arthrodesis status
The ICD-10-CM code for arthrodesis status is Z98.1 (Arthrodesis status).
Within Z98 (other postprocedural states), Z98.1 is specifically for arthrodesis status. Related codes cover intestinal bypass and anastomosis status (Z98.0), presence of cerebrospinal fluid drainage device (Z98.2), post therapeutic collapse of lung status (Z98.3), cataract extraction status (Z98.4), sterilization status (Z98.5), angioplasty status (Z98.6) and other specified postprocedural states (Z98.8).
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.
