Florida Statutes Title XXXVII. Insurance § 627.622. Insurance with other insurers

(1) The contract may include the following provision:

“Insurance with Other Insurers: If there is other valid coverage, not with this insurer, providing benefits for the same loss on a provision-of-service basis or on an expense-incurred basis and of which this insurer has not been given written notice prior to the occurrence or commencement of loss, the only liability under any expense-incurred or service coverage of this policy shall be for such proportion of the loss as the amount which would otherwise have been payable plus the total of the like amounts under all such other valid coverages for the same loss of which this insurer had notice bears to the total like amounts under all valid coverages for such loss, and for the return of such portion of the premiums paid as shall exceed the pro rata portion for the amount so determined. For the purpose of applying this provision when other coverage is on a provision-of-service basis, the ‘like amount’ of such other coverage shall be taken as the amount which the services rendered would have cost in the absence of such coverage.”

(2) If the foregoing policy provision is included in a policy which also contains the policy provision set out in s. 627.623, there shall be added to the caption of the foregoing provision the phrase: “--Expense-incurred Benefits.” The insurer may, at its option, include in this provision a definition of “other valid coverage,” approved as to form by the office, which definition shall be limited to coverage provided by organizations subject to regulation by the insurance law of any jurisdiction. In the absence of such definition, such term does not include group insurance, automobile medical payments insurance, or coverage provided by health care services plans or by union welfare plans or employer or employee benefit organizations. Any benefit provided for an insured pursuant to any compulsory benefit statute shall in all cases be deemed to be “other valid coverage” of which the insurer has had notice. In applying the foregoing policy provision, no third-party liability coverage shall be included as “other valid coverage.”
