About coding cardiac pulse generator removal
The ICD-10-CM code for cardiac pulse generator removal is Z45.010 (Encounter for checking and testing of cardiac pacemaker pulse generator [battery]).
Within Z45.01 (encounter for adjustment and management of cardiac pacemaker), Z45.010 is specifically for encounter for checking and testing of cardiac pacemaker pulse generator [battery]. Related codes cover adjustment and management of other part of cardiac pacemaker (Z45.018).
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 314 (Other Circulatory System Diagnoses with MCC, relative weight 2.0873), DRG 315 (Other Circulatory System Diagnoses with CC, relative weight 0.9508) and DRG 316 (Other Circulatory System Diagnoses without CC/MCC, relative weight 0.6677), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
