Plaintiffs appeal the district court’s grant of summary judgment against their claim that the Laborers Health & Welfare Trust Fund improperly denied them benefits. We affirm.
BACKGROUND
Alvin Jones is a participant in an insurance plan that defendant Trust Fund provides. This dispute arose when the Trust Fund refused to pay for certain treatments for Jones’s wife, who was suffering from breast cancer. The Trust Fund denied payment for these treatments — a regimen of hyperthermia — because they were “not medically necessary.” The Trust Fund relied on the opinion of its medical consultant, Dr. White, who stated that hyperther-mia was “experimental” and “not therapeutically effective.” Jones presented the testimony of Dr. Bicher, the physician who prescribed the hyperthermia treatment. Bicher stated that the treatment was effective and that other insurance carriers pay for it. Jones appealed the Trust Fund’s denial of benefits to the district court, which upheld the Trust Fund’s decision. Jones now appeals the district court’s decision.
DISCUSSION
A. Standard of Review
Plaintiffs argue that the district court relied on an improper standard of review in granting summary judgment. Traditionally, courts applied the “arbitrary and capricious” standard in reviewing denial of benefits by ERISA fiduciaries and administrators.
See, e.g., Jung v. FMC Corp.,
The district court found that the Trust Fund had discretionary authority to interpret the Plan, and applied the “abuse of discretion” standard. We affirm that decision. Article IV, Section 5 of the Trust Agreement provides:
The Board of Trustees shall have power:
(K) to construe the provisions of this Trust Agreement and the Plan, and any such construction adopted by the Board in good faith shall be binding. ...
This language indicates discretion requiring deferential review.
See Exbom v. Central States, Southeast and Southwest Areas Health & Welfare Fund,
Plaintiffs argue that the district court “nullified” the abuse of discretion standard by equating it with the arbitrary and capricious standard formerly applied. Because the Trust Fund did not violate the applicable abuse of discretion standard, we need not determine how these two standards of review may differ.
B. Plan Interpretation
Plaintiffs also argue that the Trust Fund abused its discretion by incorporating into the Plan an “experimental” medical practice exclusion which clearly conflicts with the plain language of the plan itself.
See Johnson v. Trustees of the Western Conference of Teamsters Pension Trust Fund,
C. Factual Findings
Finally, plaintiffs argue that the Trust Fund erred by basing its decision on erroneous factual findings. In order to constitute an abuse of discretion a trustee’s factual findings must be “clearly erroneous.”
See Hunt v. National Broadcasting Co., Inc.,
The language of the collective bargaining agreement provides the means by which the Trust Fund operates. The parties negotiate a collective bargaining agreement. Its life is fixed by contract. If any provision proves unsatisfactory in practice, it can be changed through subsequent contract negotiation. We will not upset the review process the parties have bargained for, absent an abuse of discretion by the Board. We find no abuse of discretion.
AFFIRMED.
