CMS has revealed the results of the OIG's recent audits of chiropractic claims, and the outcome is dismal. The agency found that "a significant portion of the claims" were paid inappropriately, with the following among the most common errors, according to MLN Matters article SE1101: CMS stresses in the article that "When further improvement cannot reasonably be expected from continuing care, the services are considered maintenance therapy, which is not medically necessary and therefore not payable under Medicare." In addition, Medicare only reimburses chiropractic treatment for patients with documented subluxations. "You must place the AT modifier [Acute treatment] on a claim when providing active/corrective treatment to treat acute or chronic subluxation," CMS adds.
