Purpose To estimate the annual volume and cost of ventral hernia repair (VHR) performed in the United States. Methods A retrospective cohort study was performed using the National Inpatient Sample (NIS) and the Nationwide Ambulatory Surgery Sample (NASS) for 2016–2019. Patients over the age of 18 who underwent open (OVHR) or minimally invasive ventral hernia repair (MISVHR) were identified. NIS procedural costs were estimated using cost-to-charge ratios; NASS costs were estimated using the NIS cost-to-charge ratios stratified by payer status. Costs were adjusted for inflation to 2021 dollars using US Bureau of Labor Statistics Consumer Price Index. Results On average 610,998 VHRs were performed per year. Most were outpatient (67.3% per year), and open (70.7%). MIS procedures increased from 25.8% to 32.8% of all VHRs. Inpatient OVHR had significantly higher associated cost than MISVHR [$35,511 (34,100–36,921) vs. $21,165 (19,664–22,665 in 2019]. Outpatient MISVHR was more expensive than OVHR [$11,558 (11,174–11,942 MIS vs. $6807 (6620–6994) OVHR in 2019]. The estimated cost of an inpatient MISVHR remained similar between 2016 and 2019, from $20,076 (13,374–20,777) to $21,165 (19,664–22,665) and increased slightly from $9975 (9639–10,312) to $11,558 (11,174–11,942) in the outpatient setting. The estimated cost of an inpatient OVHR increased from $31,383 (30,338–32,428) to $35,511 (34,100–36,921), while outpatient costs increased from $6018 (5860–6175) to $6807 (6620–6994). VHR costs decreased slightly over the study period to a mean cost of $9.7 billion dollars in 2019. Conclusion Compared to 2006 national data, VHRs in the United States have almost doubled to 611,000 per year with an estimated annual cost of $9.7 billion. A 1% decrease in VHR achieved through recurrence reduction or hernia prophylaxis could save the US healthcare system at least $139.9 million annually.
