Suitability of administrative claims databases for bariatric surgery research - is the glass half-full or half-empty?

ABSTRACT:

Background

Claims databases are generally considered inadequate for obesity research due to suboptimal capture of body mass index (BMI) measurements. This might not be true for bariatric surgery because of reimbursement requirements and changes in coding systems. We assessed the availability and validity of claims-based weight-related diagnosis codes among bariatric surgery patients.

Methods
