In H.K. Porter Co., Inc. v. Workmen's Compensation Appeal Bd., 100 Pa. Commw. 393, 514 A.2d 996, 998-99 (Pa. Cmwlth. 1986) (Porter), the Court ruled on the appealability of an order denying an employer's petition for a physical examination of claimant filed pursuant to Section 314 of the Workers' Compensation Act (Act). The employer filed this petition with the Board as part of an ongoing proceeding on employer's primary petition seeking to resolve whether claimant's injury was a new injury or an aggravation of a prior injury.

H.K. Porter, 514 A.2d at 998.

Id. Therefore, the Court ruled that a decision on an order to compel medical examination was interlocutory because it could be appealed together with the merits of the primary petition. Id.
