The District Court of Appeal, Third Division answered this question in the affirmative.
In the matter of Millennium Diagnostic Imaging Ctr., Inc. v. United Auto Ins. Co., 975 So. 2d 1149 (Fla. 3d DCA 2009), the Court held the following:
The language in section 627.736(4)(b) pertains to PIP benefits that are “due” under the policy. If a medical bill is submitted for treatment that is not reasonable, related, or necessary, there can possibly be no benefits “due” under the policy, and therefore, that claim cannot be deemed “overdue.” Section 627.736(4)(b) provides that the insurer can assert, “at any time, including . . . after the 30-day time period for payment,” that “the claim was unrelated, was not medically necessary, or was unreasonable.”
Based on the unambiguous language of section 627.736(4)(b) and applicable case law, we answer the certified question, as phrased by the trial court, in the affirmative, and conclude that the thirty-day time period set forth in section 627.736(4)(b) does not apply to claims for unrelated, unreasonable, or unnecessary treatment. Therefore, an insurer may challenge such treatment at any time, and is permitted to rely on a report, obtained pursuant to section 627.736(7)(a), even if the report is obtained more than thirty days after the claim was submitted. The insurer, however, must keep in mind that if its challenge fails, it will be liable for interest and attorney’s fees.
Oh I forgot to add that I was referencing Florida law. Compare, Bronx Expert Radiology, P.C. v. New York Cent. Mut. Fire Ins. Co. 24 Misc.3d 134(A)(App. Term 1st Dept. 2009); Dilon Medical Supply Corp. v. New York Cent. Mut. Ins. Co., 18 Misc.3d 128(A)(App. Term 2d Dept. 2007).
