Alignment of diagnosis and pharmacy claims data coding of medication adherence among patients with diabetes or hypertension.

J Manag Care Spec Pharm 2021 Apr;27(4):497-506

Division of Nephrology, University of Tennessee Health Science Center, and Memphis VA Medical Center, Memphis, TN.

ICD-10-CM codes exist that facilitate provider designation of patients as "nonadherent to therapy"; however, it is unclear whether this label accurately reflects patient behavior according to widely accepted medication adherence metrics using pharmacy claims data. To determine the extent to which patients are accurately coded for and have calculated rates of nonadherence using ICD-10-CM codes and claims, respectively.
