It is not uncommon for a defendant to overpay permanent disability (PD) benefits. An overpayment might occur for several reasons. The defendant might not receive the physician's report declaring the applicant permanent and stationary until long after the evaluation. Or a defendant simply might make a mistake and pay more PD than required. Labor Code § 4909 states, "Any payment, allowance, or benefit received by the injured employee ... [that] was not then due and payable ... shall not, in the absence of any agreement, be an admission of liability for compensation on the part of the employer, but any such payment, allowance, or benefit may be taken into account by the appeals board in fixing the amount of the compensation to be paid."

They have allowed defendants to apportion to asymptomatic previous conditions, risk factors and even genetic factors. The only limitation has been that to apportion under § 4663, the physician's opinion about apportionment must be substantial evidence. Labor Code § 4664 is the other statute that addresses apportionment in the California workers' compensation system, and it allows apportionment to a previous award of permanent disability benefits. LC 4664(b) states, "If the applicant has received a prior award of permanent disability, it shall be conclusively presumed that the prior permanent disability exists at the time of any subsequent...
