34 Pa. Code § 127.254
Notice
The hearing officer did not err in resolving the fee review dispute in favor of the provider, where the insurer notified the provider that it was not paying because of the unproven nature of the treatment and shifted to the coding issue only after the review was underway and where insurer fails to strictly comply with notice requirements. Philadelphia v. Medical Fee Review Hearing Office, 737 A.2d 356 (Pa. Cmwlth. 1999).
