Before SCHWAB, C.J., and THORNTON, BUTTLER and JOSEPH, JJ.
THORNTON, Judge.
Plaintiff appeals from an order granting summary judgment in favor of defendant insurance company.
The undisputed facts show that plaintiff's decedent was a pedestrian killed instantaneously when struck by a car driven by defendant's insured. Defendant paid funeral expenses but refused to satisfy plaintiff's demand for lost wages allegedly due *285 by reason of a clause in the policy, required by ORS 743.800(3) and (4),[1] providing for payment of 70 percent of an injured person's lost wages during the period of disability stemming from the injury. Plaintiff's demand was for wages lost over the 52 week life of the policy.
The statute which requires PIP coverage does not define the term "disability" and the question is one of first impression. In Hamrick v. State Farm Mutual Automobile Insurance Co., 270 S.C. 176, 241 S.E.2d 548 (1978), the South Carolina Supreme Court considered the meaning of "disability" in the context of their PIP statute which covered medical, ambulance, hospital and funeral expenses and disability benefits including "in the case of an income producer, payment of benefits for loss of income as the result of the accident." S.C.Code § 56-11-110.
The court stated:
"The key concept embodied in PIP no fault coverage is that an injured person needs to promptly pay expenses necessarily arising out of injuries sustained, and needs support for himself and his family during the period of recuperation. The Act appreciates the fact that contested negligence tort actions are often prolonged and do not provide for the needs of injured persons at the time when need is greatest. It is not the function of PIP no fault insurance coverage to provide funds for the creation or enhancement of one's estate. * * * The fact that one is not entitled to PIP no fault benefits does not, of course, limit his right of action in tort. Income which might have been earned after death is properly collectible in a tort action." 270 S.C. at 180, 241 S.E.2d at 549-50.
In a similar case, Griffin v. Travelers Indemnity Co., 328 So.2d 207 (Fla.App. 1976), the court reasoned that including death within the definition of disability was tantamount to providing an automatic death benefit equal to maximum disability benefits, a result which there was no indication the legislature intended. We note in this regard that our legislature in the workers' compensation context clearly distinguished permanent total or other disability benefits and death benefits, and that "disability" refers to loss of function while the injured person is living. Cf. ORS 656.204 and 656.206(1)(a). We note also that the language of ORS 743.800(3) and (4) contemplates that the injured person will ultimately return to work. We conclude that the above-quoted language from Hamrick accurately states the intent of our legislature with respect to the meaning of "disability."
It follows that summary judgment for defendant was properly granted unless it was estopped to assert that lost wages after death were outside the policy coverage. We hold it was not estopped. The recent case of Wyoming Sawmills, Inc. v. Transportation Insurance Co., 282 Or. 401, 578 P.2d 1253 (1978), is directly in point. There, the court distinguished Ward v. Queen City Fire Insurance Co., 69 Or. 347, 138 P. 1067 (1917), in which the court held that an insurer which denies coverage on the basis of one exclusion cannot wait until trial and assert that another exclusion precludes coverage:

*286 "No distinction is made in Ward between failure to assert that the claim falls within the insuring clause originally granting coverage as compared with a failure to assert an exclusion from the original grant of coverage. It seems obvious that the rule must be limited to failure to assert an exclusion. Waiver or estoppel cannot be the basis for creating an original grant of coverage where no such contract previously existed. Schaffer v. Mill Owners Insurance Co., 242 Or. 150, 156, 407 P.2d 614 (1965)." (Emphasis in original.) 282 Or. at 410, 578 P.2d at 1258.
Since lost wages after death are not within the original policy coverage, defendant was not estopped to assert that proposition as the basis for summary judgment.
The remaining issues do not warrant discussion.
Affirmed.
