Insurance and regulatory

Close-out letter

The vocabulary of getting a claim paid, of FDA enforcement, and of what on-label and off-label really mean.

Definition

FDA's confirmation that a company has corrected what a warning letter cited. ⚠ We do not track close-outs, so the presence of a letter in this register tells you FDA said something — not how the company answered or whether the matter ended there. Ask the company; they will usually tell you, and how they answer is informative.
