FLETCHER, Presiding Justice.
The issue in this granted certiorari is whether an uninsured motorist (UM) carrier may set off medical payments made by the tortfeasor's insurance carrier. Because the policy at issue in this case contains no provision for such a set-off, we hold that set-off is not permissible and reverse.
Jamie Anderson was injured while a passenger in a car driven by Meagan Mullinax. Cincinnati Insurance Co., which provided automobile liability insurance to Meagan's parents, paid Jamie's medical expenses under the medical payments coverage, but denied all other liability for Jamie's injuries because Meagan was not an insured under her parents' policy.[1] Jamie's parents sued the Mullinaxes and served State Farm, their own UM carrier. The Andersons settled with State Farm for $25,000.00 for Jamie's pain and suffering and went to trial on stipulated facts with the sole issue being whether State Farm was entitled to a set-off for the $30,000.00 in medical expenses previously paid by Cincinnati. The trial court held that State Farm was entitled to a set-off and the court of appeals affirmed.[2]
1. Both the trial court and the court of appeals addressed the question of whether a set off is generally allowable under the uninsured motorist statute and as a matter of policy. However, the starting point for interpretation of contracts for insurance is the contract itself.[3] The Andersons argue *797 that the UM coverage at issue here does not permit reduction of payments for medical expenses paid by a third-party insurer. The UM coverage of the policy provides that expenses paid under "the medical payments coverage will not be paid for again as damages under this coverage." A similar clause was held in Johnson v. State Farm[4] to permit reduction of payments under UM coverage for amounts paid under the medical payments coverage of the same policy. This clause does not, however, authorize reduction of payments under UM coverage for amounts paid as medical payments under any policy of insurance. This interpretation is supported by other language under the UM coverage that broadly authorizes reduction for amounts paid under "any policy of property insurance" and under "any worker's compensation, disability benefits or similar laws."
2. State Farm argues that a denial of a set-off is contrary to the purpose of UM coverage to place the insured in the same position as if the tortfeasor had liability coverage. Even though there is no public policy interest in encouraging double recovery under UM coverage,[5] the primary responsibility for writing coverage that limits the insurer's obligation to actual losses lies with the insurer in the drafting of its contract.[6] Because State Farm's policy does not authorize the set-off it seeks, we must reverse.
Judgment reversed.
All Justices concur.
