Background: The objective of this study was to identify the neurosurgical MS-DRGs highest national bills and to analyze economic, demographic, and patient outcome trends. Methods: This retrospective cohort study used the Nationwide Inpatient Sample (NIS) database to achieve the results. All MS-DRG codes for the years 2014 were ranked based on total aggregate charges. The highest ranked relevant to neurosurgery were identified and retrospectively reviewed to 2008. The data was analyzed by Z-test. Results: In 2014, NIS reported the MS-DRG with the highest national bill of $22,894,340,928 was “Spinal Fusion Except Cervical without MCC,” which also had the largest rise over the cohort period, increasing from $15,853,679,222 in 2008 (p <.001). It was also the MS-DRG with the highest incidence, totaling 1,443,112 discharges and increasing from 190,692 in 2008 to 214,100 in 2014 (p <.10). “Craniotomy with major Device Implant/Acute Complex CNS Procedure w/MCC or Chemo Implant” had the longest length of stay (LOS) with a mean patient stay of 12.9 days. This MS-DRG also had the oldest patient population mean age of 57.5 years old. “Craniotomy & Endovascular Intracranial Procedures with MCC” had the most in-hospital deaths totaling 28,707 increasing significantly from 3602 in 2008 to 4410 in 2014 (p <.05). Conclusions: “Spinal fusion except cervical without MCC,” had the highest national bill in the USA over the period of the cohort. Healthcare organizations can benefit from awareness of this information by using it to establish the most efficient healthcare investments and preparing a health-care roadmap for the following decades.
