Ordered that the order is reversed insofar as appealed from, without costs and disbursements, the father's objection to that portion of the order of the Hearing Examiner which directed that "any unreimbursed medical expenses for the children are to be divided equally" is sustained, and the order of the Hearing Examiner is vacated insofar as objected to.
It was error for the court to direct the father to pay one half of his children's unreimbursed medical expenses since such payments are in the nature of improper, open-ended obligations (see, Keehn v Keehn, 137 A.D.2d 493, 496; Armando v Armando, 114 A.D.2d 875; see also, Weinstein v Weinstein, 125 A.D.2d 301). Ordinary or routine unreimbursed medical expenses should properly be considered an element of support and be included within the fixed weekly support award (see, Family Ct Act § 416). However, extraordinary unreimbursed expenses, such as those incurred at bar for the hospitalization and psychiatric treatment of the parties' son, cannot be awarded prospectively in unfixed amounts. Rather, the mother is required to make application to the Family Court to compel the father to pay his fair share of a specific fixed extraordinary medical expense (Keehn v Keehn, 137 A.D.2d, at 497, supra).
