In recent years there have been more studies dedicated to Peyronie’s disease (PD). However, prevalence and incidence are likely underestimated, with limited information on regional variation in the rate of diagnosis. In this study, we sought to estimate age and regional variation of the annual incidence and prevalence of PD in the United States. We reviewed data from the IBM MarketScan™ Claims and Encounters database between 2008-2017 for men ≥18 years. Inclusion required ≥1 medical claim with PD, identified by ICD-9 and ICD-10 codes or ≥1 claim for intralesional injection for PD, identified by Current Procedure Terminology (CPT) code. Overall average annual incidence was estimated at 20.9 cases per 100,000, with the highest rate of 41.6 cases per 100,000 observed in men 55–64 years (RR = 8.2; p < 0.0001). Geographically, the highest incidence rate was observed in the South (23.9 cases per 100,000 men; RR = 1.30; p < 0.0001). Across all ages, overall prevalence of PD showed a general upward trend, from 0.052% in 2008 to 0.096% in 2017. Our findings suggest men in the southern U.S. are diagnosed more with PD compared to other regions. Identification of associated factors may allow for a more proactive approach to diagnosis and management.
