VIDEO: Nearly half of Medicaid patients denied antivirals for HCV


 

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY

State Medicaid programs denied nearly half of requests to cover direct-acting antiviral drugs for patients with chronic hepatitis C virus (HCV) infection, according to a prospective study of beneficiaries in Delaware, Maryland, New Jersey, and Pennsylvania reported in the July issue of Clinical Gastroenterology and Hepatology.

In contrast, only 5% of Medicare patients and 10% of privately insured patients were denied coverage, said Dr. Vincent Lo Re III of the University of Pennsylvania, Philadelphia, together with his associates. “Notably, nearly one-quarter of Medicaid recipients with cirrhosis experienced treatment denial. Medicaid patients from these states also experienced a longer time to prescription fill than those with Medicare or commercial insurance,” the researchers said.

Their study included 2,321 HCV patients prescribed a direct-acting antiviral regimen between November 1, 2014 and April 30, 2015. All prescriptions were submitted to a specialty pharmacy that serves HCV patients in Maryland, Pennsylvania, Delaware, and New Jersey, the investigators noted. They focused on “absolute denial,” meaning that the prescription was never filled because the insurer denied coverage, regardless of appeals. “Data are lacking on the incidence of absolute denial of direct-acting antiviral prescriptions and factors associated with this outcome,” the investigators said. “These data are important because absolute denial of HCV treatment by insurers might have adverse outcomes on patients and could harm patient-provider relationships” (Clin Gastroenterol Hepatol. 2016 Apr 5. doi: 10.1016/j.cgh.2016.03.040).

A total of 1,023 study patients were privately insured, 795 were enrolled in Medicare, and 503 were Medicaid patients, according to the researchers. In all, 377 patients (16%) received absolute denials, most often because of “insufficient information to assess medical need” (36% of denials) and “lack of medical necessity” (35%). Medicaid patients faced an absolute denial rate of 46% – significantly higher than rates for private insurers (10.5%) or Medicare (5%; P less than .001 for both comparisons). After adjusting for potential confounders, Medicaid patients were more than four times as likely to be denied coverage for direct-acting antivirals, compared with privately insured patients (relative risk, 4.1; 95% confidence interval, 3.4-5.1). Delaware’s Medicaid program had the highest rate of absolute denial (57%), followed by Pennsylvania (48%), Maryland (47%), and New Jersey (37%).

Medicaid programs even refused to cover direct-acting antiviral prescriptions for 25% of patients who had cirrhosis, compared with absolute denial rates of only 1% for Medicare and 3% of private insurers (P less than .001 for both comparisons), according to the researchers. The implications of these denials “remain unknown,” but lack of treatment increases the risk of end-stage liver disease, hepatocellular carcinoma, extrahepatic disease, HCV transmission, and “anxiety and stress about HCV disease progression, [which can] provoke distrust among patients of the health care system and their providers,” they added. “Clinicians then are challenged to explain the denial, and important opportunities for patient engagement, education, and cure could be irrevocably lost.”

Medicaid programs also initially denied about 25% of prescriptions before eventually approving them, despite the fact that “patients had complete prior authorization requests that should have contained the materials needed to justify approval,” said the investigators. Furthermore, denial letters usually did not specify the information that was needed, “making it difficult [for clinicians] to appeal the decision.” In contrast, only about 8% of privately insured patients and 13% of Medicare enrollees were initially denied coverage.

Prescriptions as a whole were more likely to be filled in the last 3 months of the study than earlier, perhaps because insurers are starting to relax their reimbursement criteria, said the investigators. Indeed, in October 2015, the American Association for the Study of Liver Diseases and the Infectious Disease Society of America stopped triaging groups of patients for direct-acting antiviral therapy, they noted.

The research was supported by the Penn Center for AIDS Research, which is funded by the National Institutes of Health. Dr. Lo Re received investigator-initiated research support from AstraZeneca. Five coinvestigators reported relationships with a number of pharmaceutical companies. Four coinvestigators reported employment by the study site, Burman’s Specialty Pharmacy. The other four coauthors had no disclosures.
