(a) If, at any time after the completion of initial medical examinations and tests, unresolved medical questions remain, the deputy commissioner may cause the claimant to be examined by a physician selected by the deputy commissioner.
(b) Any miner dissatisfied with the results of the medical examinations or tests conducted under 725.406 may obtain further medical examinations or tests and submit them to the deputy commissioner. Such further examinations or tests shall be reimbursable by the fund, or by a responsible coal operator where appropriate, if the claimant is finally adjudicated entitled to benefits and if such further examinations or tests were relevant to the determination of the claim.
(c) If additional medical evidence is obtained in accordance with paragraph (a) of this section, the deputy commissioner may order the physician selected to retest or reexamine the miner to do so without the presence or participation of any other physician who previously examined the miner, and without benefit of the conclusions of any other physician who has examined the miner.
