"BCBS analyzed data collected in the first nine months of 2015, which showed that the newly enrolled BCBS beneficiaries experienced higher rates of hypertension, diabetes, coronary artery disease, and depression. BCBS predicted that if it were able to collect data for the full year, the higher prevalence among the new enrollees would be even more pronounced. Further, the study found that the newly enrolled also had a higher prevalence of HIV and Hepatitis C.... BCBS identified an increase of 12 percent, or a jump from $501 to $559, when it came to the average monthly medical costs of individuals who were enrolled in BCBS plans after the ACA took effect."
