The Health and Economic Burden of Genital Warts in a Set of Private Health Plans in the United States

We estimated the prevalence of and costs associated with genital warts among privately insured individuals from the perspective of a private health plan in the United States. Health care claims data were derived from a sample of 3,664,686 privately insured individuals. The database was limited to cases of disease for which an insurance claim was generated, with costs reflecting inpatient, outpatient, and pharmacy payments from all sources. We identified 5095 cases of genital warts (1.7 cases per 1000 person-years) billed through the health plans during 2000. The prevalences of and health plan costs associated with genital warts were highest among women aged 20-24 years (6.2 cases and $1692 in costs per 1000 person-years) and men aged 25-29 years (5.0 cases and $1717 in costs per 1000 person-years). On average, individual episodes of care for genital warts involved 3.1 physician visits and incurred costs of $436. These are the first age- and sex-specific estimates of the prevalence and cost of genital warts for a US health plan.
