  • Data are n (%).

  • *

    * ICD-9-CM code appropriately corresponding with clinical diagnoses.

  • A single visit was chosen at random in cases where a patient had multiple visits with a type 2 diabetes ICD-9-CM code.

  • For the purposes of coding assignment, we included satellite Endocrine/Diabetes Programs and the inpatient Endocrine/Diabetes Service in this category.

  • §

    § One patient with this diagnosis did not have an available assignment for the source of the ICD-9-CM code.

  • A specific ICD-9-CM code for insulin resistance or hyperinsulinemia is not currently available. Options include 277.7 (dysmetabolic syndrome X) or 251 (other disorders of pancreatic internal secretion).
