Opinion
PETERSON, P. J.
In this case, we hold that the Workers’ Compensation
Appeals Board (Board) did not have jurisdiction to alter the permanent and stationary date of the earliest industrial injury sustained by respondent Thelma Swain Gill (applicant), in order to apply the principles enunciated in
Wilkinson
v.
Workers’ Comp. Appeals Bd.
(1977) 19 Cal.3d 491 [138 Cal.Rptr. 696, 564 P.2d 848] (Wilkinson) and to award applicant a single combined permanent disability (PD) rating of 100 percent for her three successive industrial injuries. Even though the threshold prerequisites of
Wilkinson
are met and the medical evidence credibly supports a finding that applicant is totally and permanently disabled, apportionment of PD is appropriate pursuant to
Fuentes
v.
Workers’ Comp. Appeals Bd.
(1976) 16 Cal.3d 1 [128 Cal.Rptr. 673, 547 P.2d 449] (Fuentes) because the award of PD for applicant’s earliest injury is final and cannot be disturbed. For the reasons discussed below, we are compelled to annul and remand the decision of the Board.
I. Factual and Procedural Background
Applicant, while employed as a cook by petitioner California School for the Deaf (CSD), sustained four successive industrial injuries, as follows: (1)
on December 2, 1966, to her back (OAK 38781); (2) on October 9,1970, to her back (OAK 38782); (3) on May 19,1987, to her head, back, and right leg (OAK 157587); and (4) from 1970 to January 31, 1988, to her back and legs (OAK 159231).
On August 8,1972, findings and award issued in the first two injury cases. All of the PD emanated from the second injury sustained on October 9, 1970, in OAK 38782.
Applicant was awarded a
IVi
percent PD rating, the monetary equivalent of $1,459.50, payable at $48.65 per week pursuant to the statutory scheme in effect at the time of the 1970 injury. (Lab. Code,
§ 4658.) Subsequently, applicant timely petitioned to reopen the October 1970 injury, claiming new and further disability. The petition was granted. On June 27, 1975, applicant was awarded, as pertinent, an additional PD rating for the injury of October 9, 1970, of 20 percent, the monetary equivalent of $3,892, payable at $48.65 per week commencing on March 29, 1975. No further petitions to reopen the injury claim of October 9, 1970, were filed by applicant. The award of June 27, 1975, was final.
On September 26, 1991, findings and award issued in the latter two injury cases (OAK 157587, 159231). The workers’ compensation judge (WCJ) found applicant permanently, totally disabled as a result of all three injuries. The WCJ relied on medical opinion that applicant’s condition resulted in a limitation to semisedentary
or sedentary
work, expert vocational testimony that applicant was not feasible for vocational rehabilitation pursuant to
LeBoeuf v. Workers’ Comp. Appeals Bd.
(1983) 34 Cal.3d 234 [193 Cal.Rptr. 547, 666 P.2d 989], and applicant’s credible testimony regarding her level of pain, physical limitations, and inability to work. These findings are not contested on review.
The WCJ further determined that the three industrial injuries were to the same part of the body and became permanent and stationary at the same time. Relying on
Harold
v.
Workers’ Comp. Appeals Bd.
(1980) 100 Cal.App.3d 772 [161 Cal.Rptr. 508]
(Harold),
he issued a single combined PD award of 100 percent for all three injuries pursuant to the principles enunciated by
Wilkinson, supra,
19 Cal.3d 491. The PD was ordered payable at the PD rates in effect at the time of the last cumulative injury ending on January 31, 1988. This resulted in a total PD award to applicant for the balance of her life in the weekly amount of $224 (see §§ 4452.5, subd. (a); 4453, subd. (a)(2); 4658, subd. (a)), with monetary credit for all prior payments, including the original PD awards of
7Vi
and 20 percent for the earliest injury in October 1970.
CSD filed a petition for reconsideration. On November 5, 1991, the WCJ submitted to the Board his report on petition for reconsideration, recommending that the petition be denied. Pertinent to the issues on review, the WCJ stated: “The findings and award in OAK 38782 [1970 injury] cannot be altered now, but it may nonetheless be combined with the new cases, so long as the carrier is given credit for all it has already paid toward applicant’s 100 percent rating. [Citation to
Harold, supra,
100 Cal.App.3d at pp. 786-787.] Thus, even though applicant’s condition may have been permanent and stationary at some point in the past, the new injuries destabilized the old injury, which contributed significantly to the new [PD]. Accordingly, they should all be combined together into an overall rating, but credit given to [CSD] for what they have already paid, [f] They are not, however, entitled to ‘credit’ for that old award under [citation to
Fuentes, supra,
16 Cal.3d 1], as [CSD] requests. [Record Citation.] The
Fuentes
approach is used where apportionment is justified by the evidence, the
Wilkinson
one where it is not. Here, the evidence does not warrant apportionment for the reasons stated above.”
On December 16, 1991, the Board issued its order denying reconsideration, stating: “Based on our review of the record, and for the reasons stated in said report which we adopt and incorporate, we will deny reconsideration.”
CSD timely seeks review of the Board’s decision in this court. Applicant has filed an answer. The sole issue to be determined is whether the Board has jurisdiction to alter the permanent and stationary date of the October 1970 injury in order to apply
Wilkinson,
rather than
Fuentes,
in assessing applicant’s PD entitlement.

II. Discussion
A.
Apportionment of PD Under Fuentes
Fuentes, supra,
16 Cal.3d 1, concerned the appropriate method of assessing an employer’s liability for PD for an industrial injury where a portion of the injured employee’s overall PD was attributable to a nonindustrial disability preexisting April 1, 1972.
Applying section 4750,
the Supreme Court held that, where apportionment of a preexisting PD is appropriate, the proper method of converting the PD rating to a number of weeks of compensation under section 4658 is to apportion the disability by first subtracting the percentage, not the monetary value, attributable to the preexisting disability from the total PD rating.
(Fuentes, supra,
16 Cal.3d at pp. 5-6.) The remaining percentage of PD attributable to the industrial injury, directed the court, is then converted to its monetary equivalent.
(Ibid.)
Although
Fuentes
concerned apportionment of a preexisting nonindustrial PD, it may be applied in cases involving apportionment to a preexisting industrial PD. In these apportionment cases, the
Fuentes
approach results in a lower monetary recovery to injured employees in light of the graduated PD rate scale set forth in section 4658. However, the impact of
Fuentes
in certain successive industrial injury cases has been notably restricted, commencing with the Supreme Court’s decision in the landmark
Wilkinson
case.
B.
Wilkinson and Its Progeny
Where successive industrial injuries to the same part of the body become permanent and stationary
at the same time, the injured employee is entitled to a PD award based upon the combined disability at the
PD rates applicable at the time the last injury of the successive injuries giving rise to such benefits occurred.

neither [PD] is ‘previous’ to the other, and section 4750 hence does not require apportionment.”
{Wilkinson, supra
19 Cal.3d at p. 497, italics in original.)
Here, relying on
Harold’s
application of
Wilkinson,
and credible medical evidence that the 1970, 1987, and 1988 injuries became permanent and stationary at the same time after the 1988 injury, the Board determined that apportionment of applicant’s PD under
Fuentes
is inappropriate. Instead, the Board awarded applicant a single combined PD of 100 percent payable at the PD rates in effect in 1988.
Harold,
however, is not controlling. To the contrary, the consolidated PD award for all three injuries is flawed because the Board lacks jurisdiction to alter the previously determined permanent and stationary date for the October 1970 injury.
C.
Application of Wilkinson Must Adhere to Continuing Jurisdictional Time Limitations
Sections 5410, 5803, 5804, and 5805
govern the entire spectrum of the Board’s continuing jurisdiction.
(Sanchez
v.
Workers’ Comp. Appeals Bd.
(1990) 217 Cal.App.3d 346, 353 [266 Cal.Rptr. 21].) Section 5410 provides, as pertinent: “Nothing in this chapter shall bar the right of any injured worker to institute proceedings for the collection of compensation . . . within five years after the date of the injury upon the ground that the original injury has caused new and further disability .... The jurisdiction of the appeals board in these cases shall be a continuing jurisdiction within this period.” Section 5804 provides, as pertinent: “No award of compensation shall be rescinded, altered, or amended after five years from the date of the injury except upon a petition by a party in interest filed within such five years . . . .”
Turning to
Harold,
careful examination reveals that the court fully adhered to the statutory continuing jurisdictional time limitations when applying
Wilkinson
principles to the facts before it. In
Harold,
the injured employee sustained two successive industrial injuries to her right lower extremity in 1971 and 1973. (100 Cal.App.3d at p. 775.) In 1972, she was awarded a PD of 4 percent for the 1971 injury, payable at the weekly PD rate of $52.50 then in effect. In 1973, after Harold sustained her second injury, she not only filed a claim for that injury, but also timely petitioned in 1974 to reopen the PD awarded for the 1971 injury. In 1975, prior to
Wilkinson,
the WCJ granted the petition to reopen and increased the PD to 321/2 percent for the 1971 injury.
(Harold, supra,
100 Cal.App.3d at p. 783.) Additionally, Harold was awarded a separate PD of 33 percent for the 1973 injury, payable at the weekly PD rate of $70 due to the amendments to section 4658 effective April 1, 1972.
(Harold, supra,
100 Cal.App.3d at p. 783.) Significantly,
at the same time in 1975, when the Board had jurisdiction over both the 1971 and 1973 injuries, the WCJ also found that the two injuries became permanent and stationary at the same time. (Ibid.)
The Board granted reconsideration and annulled the WCJ’s findings. On review for the first time, the appellate court reversed, determining that the Board improperly disregarded the WCJ’s findings because there was no evidence of considerable substantiality contrary to the WCJ’s finding that both injuries became permanent and stationary at the same time. (100 Cal.App.3d at p. 786.)
Subsequently, the Supreme Court decided
Wilkinson.
On October 5, 1977, following the issuance of
Wilkinson,
Harold filed a petition to reopen the 1973 injury claim to take advantage of
Wilkinson’s
effect on her PD computation.
{Harold, supra,
100 Cal.App.3d at p. 783.) Harold did not petition to reopen the 1971 injury award because more than five years had elapsed since the date of injury, and the Board no longer had continuing jurisdiction to reopen that case.
{Ibid.,
citing §§ 5410, 5803, 5804.)
On review for a second time pertinent to the issues herein, the court initially confirmed that Harold correctly did not petition to reopen the 1971 injury award insomuch as the Board was without jurisdiction to act.
{Harold, supra,
100 Cal.App.3d at pp. 775, 786.) The court emphasized, however, that the jurisdictional bar against reopening the 1971 injury case did “not prevent the court from applying
Wilkinson, Muelle, Taylor
and
Fullmer
to the 1973 injury award to the extent possible.”
{Id.
at p. 787; accord,
Stoiber, supra,
5 Cal.App.4th at pp. 1409-1410.) Accordingly, the court awarded one consolidated PD of 65V2 percent payable for 3491/2 weeks. Next, reconciling the jurisdictional bar involving the 1971 injury,
Harold
ordered PD payments for the first 130 weeks (representing the 321/2 percent PD previously awarded for the 1971 injury) payable at the 1971 rate of $52.50, resulting in full credit for the prior payment in same amount. (100 Cal.App.3d at pp. 787-788.) The court then ordered the balance of 219.5 weeks payable at $70 per week, allowing for monetary credit for all prior payments at the lower PD rate, but also resulting in a larger monetary recovery for the overall PD awarded.
{Id.
at p. 788.)
Turning to the matter before this court, the Board relies on
Harold
as justification for its application of
Wilkinson.
We disagree. In
Harold,
unlike the instant matter, jurisdictional time limitations were
not
exceeded when the permanent and stationary date for the earlier 1971 injury was altered in reaching the final PD award. Rather,
Harold
only applied
Wilkinson
to the fullest extent allowable by law. The Board’s reliance on
Harold
is misplaced. Its error is traceable to a subtle yet critical factual distinction neglected in its otherwise careful analysis.
Volomino, supra,
illustrates this distinction.
In
Volomino,
the injured employee suffered three successive industrial injuries to the same part of the body, as required by
Wilkinson:
(1) a specific injury on October 18,1963; (2) a cumulative injury from April 1970 to April 9, 1975; and (3) a specific injury on April 9, 1975. In 1969, the Board found that the 1963 injury was permanent and stationary, and awarded a PD of 52 percent payable at $52.50 per week for 208 weeks pursuant to the appropriate statutory rates in effect at the time of injury.
{Volomino, supra,
118
Cal.App.3d at pp. 269-270.) A petition to reopen the 1963 injury was not filed within the five-year statutory time limitation period. Accordingly, the Board’s continuing jurisdiction over the 1963 injury expired. Nonetheless, the Board subsequently determined pursuant to updated medical evidence that all three of Volomino’s injuries, including the 1963 injury, became permanent and stationary at the same time, applied
Wilkinson
principles, and awarded a 100 percent PD, payable in weekly benefits for life at $119, the rate in effect at the time of the last injury in 1975.
(Volomino, supra,
118 Cal.App.3d at p. 270.) On review, the appellate court reversed. Distinguishing
Harold,
the
Volomino
court determined that the Board had erroneously applied
Wilkinson
to include the earliest of three successive industrial injuries in one combined PD rating. The Board, held
Volomino,
lacked continuing jurisdiction to alter the earlier injury. (118 Cal.App.3d at p. 275.) The court articulated as follows: “In
Harold
the injured worker within five years of the date of the 1971 injury had filed a petition to reopen the award for such injury. Thus, when the WCAB in
Harold
found that Harold’s 1971 injury and 1973 injury became permanent and stationary at the same time
the WCAB was still properly exercising its continuing jurisdiction over the 1971 injury.
Here, [Volomino’s] 1963 injury award became final in 1969, and has never been reopened. Thus, at the time of the filing of the claims for the 1975 specific injury and the cumulative trauma injury, the award for the 1963 injury had long since become final. It was improper for the WCAB to alter the permanent and stationary date for the 1963 injury to bring it up to when the current injuries became permanent and stationary so as to apply the doctrine in
Wilkinson.
Nothing in
Harold
permits the modification of the permanent and stationary date after the WCAB has lost jurisdiction; to the contrary
Harold
demonstrates that the WCAB has exceeded its jurisdiction and failed to give res judicata effect to the now final 1963 injury award.”
(Volomino, supra,
118 Cal.App.3d at pp. 274-275, italics added; accord,
Stoiber, supra,
5 Cal.App.4th at p. 1410.
)
Reviewing the instant record, we find the same pivotal fact which required
Volomino
to distinguish
Harold.
Applicant did not file, within five years of
the date of injury, a petition to reopen the
IV2
percent PD and the 20 percent supplemental PD previously awarded for the October 1970 injury. The Board did not have continuing jurisdiction over the October 1970 injury on September 26, 1991, when the WCJ altered the permanent and stationary date for the 1970 injury, determining that the three successive industrial injuries became permanent and stationary at the same time. This action clearly exceeds the Board’s continuing jurisdictional powers.
(Volomino, supra,
118 Cal.App.3d at pp. 274-275;
Harold, supra,
100 Cal.App.3d at p. 786;
Stoiber, supra, 5
Cal.App.4th at p. 1410.) To then award applicant a combined 100 percent PD for all three injuries based upon the rates in effect at the time of the last injury in 1988 disregards the finality of the 1970 injury case.
(Volomino, supra,
at p. 275;
Harold, supra,
at p. 787;
Stoiber, supra,
at p. 1410.) Nothing in
Harold
permits the Board to exceed statutorily mandated jurisdictional time limitations so that
Wilkinson
may be applied whenever updated medical evidence credibly indicates that successive industrial injuries become permanent and stationary at the same time.
Hence, we hold that the Board did not have jurisdiction to alter the permanent and stationary date for the 1970 injury. (§§ 5410, 5804;
Volomino, supra,
118 Cal.App.3d at pp. 273-275;
Harold, supra,
100 Cal.App.3d at pp. 786-787;
Stoiber, supra, 5
Cal.App.4th at p. 1410.) On the five-year anniversary date of the 1970 injury—October 9, 1975—the Board’s awards therein were final and, as such, must be given res judicata effect.
(Harold, supra,
100 Cal.App.3d at pp. 786-787, citing
Dow Chemical Co.
v.
Workmen’s Comp. App. Bd.
(1967) 67 Cal.2d 483, 491 [62 Cal.Rptr. 757, 432 P.2d 365].)
III. Conclusion
Applicant is not entitled to one consolidated PD award of 100 percent for all three injuries payable at $224 per week for life. Because the prior awards for the 1970 injury are final and the Board is without jurisdiction to alter
them in any way, the PD attributable to that injury is preexisting under section 4750. Apportionment of PD, therefore, is appropriate pursuant to
Fuentes.
Accordingly, the Board order denying reconsideration dated December 16, 1991, is annulled, and the cause remanded for further proceedings consistent with the views expressed herein.
