Big gaps seen in hospital billing data

Share this:


Johns Hopkins researchers have found serious gaps in hospital billing data that are used for such important actions as calculating hospitals’ risk for ¬†high readmission rates, surgical complications and measuring the effects of health-policy changes.

The researchers wrote that, for example, there are “glaring flaws” because of ¬†underreporting of patients’ alcohol and tobacco use, weight and body mass.

Missing data can, of course, cause inaccurate risk adjustments, and thus unfair reimbursement.
