20 CFR § 30.705 - What services are covered by the OWCP fee schedule?
(a) Payment for medical and other health services, devices and supplies furnished by physicians, hospitals and other providers for occupational illnesses or covered illnesses shall not exceed a maximum allowable charge for such service as determined by OWCP, except as provided in this section.
(b) The schedule of maximum allowable charges does not apply to charges for services provided in nursing homes, but it does apply to charges for treatment furnished in a nursing home by a physician or other medical professional. In the future, OWCP may also decide to implement a fee schedule for services provided in nursing homes.
