UNASSIGNED: National surveys suggest that millions of adults in the United States use complementary health approaches such as acupuncture, chiropractic manipulation, and herbal medicines to manage @entity158 such as @entity625 , @entity615 and @entity239 . Yet, national and per @entity1 out-of-pocket (OOP) costs attributable to this condition-specific use are unknown. In the 2007 National Health Interview Survey, use of complementary health approaches, reasons for this use, and associated OOP costs were captured in a nationally representative sample of 5,467 adults. Ordinary least square regression models that controlled for co-morbid conditions were used to estimate aggregate and per @entity1 OOP costs associated with 14 @entity158 health conditions. Individuals using complementary approaches spent a total of  14.9 billion (S.E.  0.9 billion) OOP on these approaches to manage these @entity158 . Total OOP expenditures seen in those using @entity615 ( 8.7 billion, S.E.  0.8 billion) far outstripped that of any other condition, with the majority of these costs ( 4.7 billion, S.E.  0.4 billion) resulting from visits to complementary providers. Annual condition-specific per- @entity1 OOP costs varied from a low of  568 (SE  144) for @entity10 , to a high of  895 (SE  163) for @entity239 . PERSPECTIVE: Adults in the United States spent  14.9 billion OOP on complementary health approaches (e.g., acupuncture, chiropractic, herbal medicines) to manage @entity158 including @entity615 ( 8.7 billion). This @entity615 estimate is almost 1/3(rd) of total conventional healthcare expenditures for @entity615 ( 30.4 billion) and 2/3(rds) higher than conventional OOP expenditures ( 5.1 billion).
