The principal question presented in this workman’s compensation case is: What is the proper procedure to be followed when a claim is made for aggravation of a previously accepted claim for disability because of occupational disease?
The statutes establish administrative procedures to be followed when an original claim is for accidental injury, see, ORS 656.262 to 656.382, and when an original claim is for occupational disease benefits, see, ORS 656.802 to 656.824, the principal difference being that a Medical Board of Review makes a final determination of certain facts in an occupational disease case. The statutes also establish procedures for processing claims of aggravation of an accidental injury, ORS 656.271, which are the same as are followed in processing an original claim for accidental injury. However, the statutes do not explicitly describe the procedures to be followed in a case, like this one, involving aggravation of an occupational disease.
The State Accident Insurance Fund argues these types of claims should go from the hearing officer to a Medical Board of Review, just as an original claim *102for occupational disease benefits does. Claimant argues the proper procedures in this case are the same as would be followed in an aggravation-of-an-accidental-injury case.
We are persuaded that claimant’s interpretation of the statutes is the more reasonable one. OES 656.271, which establishes procedures for claims of aggravation of an accidental injury, applies when
“* * * subsequent to the last award or arrangement of compensation there has been an aggravation of the disability resulting from a compensable injury * * (Emphasis supplied.)
OES 656.804(1) provides:
“An occupational disease * * * is considered an injury * * * except as otherwise provided in OES 656.802 to 656.824.” (Emphasis supplied.)
These two sections, read together, suggest the same procedures are to be followed in processing all aggravation claims.
We find nothing in OES 656.802 to 656.824 that provides otherwise. The general rule there stated is:
“The procedure for * * * processing * * * occupational disease claims shall be the same as provided for accidental injuries # OES 656.807 (4).
This general rule is subject to one important exception :
“In every case of the rejection of a final order of the hearing officer under OES 656.808, involving the issues enumerated in ORS 656.812, there shall be appointed a medical board of review, which board of review shall have jurisdiction to pass upon and decide such issues.” OES 656.810(1). (Emphasis supplied.)
*103Looking to the issues enumerated in OES 656.812 it appears to us that the five statutory questions in that section are for the most part irrelevant to an aggravation claim.
We hold that OES 656.271 applies to all aggravation claims. We note that the record in this case indicates the Workmen’s Compensation Board agrees with this interpretation of the statutes, since it considered the claim here involved.
The proper procedures were followed in this case up to a point. Claimant appealed the hearing officer’s adverse determination to the Workmen’s Compensation Board, and then further appealed to the circuit court. However, the trial judge then ordered that the claim be
* *= remanded to the Workmen’s Compensation Board for the convening of a Medical Board of Eeview for the sole purpose of establishing the extent or degree of disability resulting from the aggravation of the claimant’s occupational disease
Under the view we have adopted of the statutes in question this was error. The trial judge should have determined the matter on the merits, just as would be done in any other aggravation claim appealed to the circuit court.
The trial judge also ordered the State Accident Insurance Fund to pay claimant’s attorney fees based on OES 656.386(1), which provides:
“In all cases involving accidental injuries where a claimant prevails in an appeal to the circuit court from a board order denying his claim for compensation, the court shall allow a reasonable attorney’s fee to the claimant’s attorney * * (Emphasis supplied.)
*104This order was premature since claimant has not yet prevailed on the merits in the circuit court. Peterson v. Compensation Dept., 257 Or 369, 477 P2d 216 (1970).
Reversed and remanded for further proceedings in accordance with this opinion.
