Trends in utilization and spending on remote monitoring of pacemakers and implantable cardioverter-defibrillators among Medicare beneficiaries

BACKGROUND National trends and costs associated with remote and in-office interrogations of pacemakers and implantable cardioverter-defibrillators (ICDs) have not been previously described. OBJECTIVE The purpose of this study was to evaluate utilization and Medicare spending for remote monitoring and in-office interrogations for pacemakers and ICDs. METHODS We performed a retrospective cohort study of claims and spending for remote and in-office interrogations of pacemakers and ICDs for Medicare fee-for-service beneficiaries from 2012 to 2015. Aggregate and per-beneficiary claims and spending were calculated for each device type. RESULTS Among all patients, 41.9% were female and the mean age was 78.3 years. From 2012 to 2015, remote monitoring utilization increased sharply. Aggregate professional remote monitoring claims for pacemakers increased by 61.3% and for ICDs by 5.6%, with an increase in technical claims (combined for pacemakers and ICDs) of 32. 8%. Spending on all remote and in-office interrogations for these devices totaled $160 million per year, with remote costs increasing nearly 25% from $45.4 million in 2012 to $56.7 million in 2015. At the beneficiary level, remote interrogations increased for pacemakers from 0.6 to 0.9 per year, and for ICDs from 1.3 to 1.4 per year, whereas in-office interrogations decreased from 2.8 to 2.7 per year and from 3.0 to 2.9 per year, respectively. Beneficiary-level analysis revealed increased expenditures on remote interrogation offset by decreases in in-office expenditures, with total annual spending decreasing by $2 and $5 per beneficiary, respectively. CONCLUSION Remote monitoring utilization increased substantially from 2012 to 2015, whereas annual costs per beneficiary decreased.
