In California, temporary disability under Labor Code §4653 pays two-thirds of wages during recovery; permanent disability under §4658 starts at maximum medical improvement based on the §4660 rating. TD caps at 104 weeks; PD pays per schedule. Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, sorts the transition. Request a free case review.
The most common phone call a California workers' compensation attorney gets from a long-term injured worker is some version of: "I just got a smaller check than usual — what is it and where did the rest of my money go?" The answer is almost always that the worker has transitioned from temporary disability under California Labor Code §4653 to permanent disability under California Labor Code §4658 — or from temporary disability to nothing while waiting for the QME under California Labor Code §4062.2 to issue a rating. The transition is governed by the date the treating physician declares the worker permanent and stationary (P&S, also known as maximum medical improvement or MMI), the 104-week cap on temporary disability, and the AMA Guides 5th Edition impairment percentage that determines permanent disability indemnity.
The two benefits are completely different in structure. Temporary disability under California Labor Code §4653 is two-thirds of the worker's pre-injury average weekly wage, paid every two weeks during recovery, capped at 104 compensable weeks within five years. Permanent disability under California Labor Code §4658 is paid over the schedule's number of weeks based on the rating under California Labor Code §4660 — a 30% PD pays for a set number of weeks at a set weekly rate, a 60% PD pays longer, a 70%+ PD triggers a life pension under California Labor Code §4659. The Supplemental Job Displacement Benefit voucher under California Labor Code §4658.7 sits separately on top of PD and is worth up to $6,000 for retraining if the employer does not offer regular, modified, or alternative work within 60 days of P&S.
Yazdchi Law represents injured California workers statewide from a home office at 1125 W Avenue M-14 in Palmdale, with appearances at the Van Nuys, Bakersfield, Los Angeles, Long Beach, Pomona, San Bernardino, Riverside, and Oxnard WCAB district offices. Eman Yazdchi is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California. This page lays out the TD-to-PD transition honestly — what triggers each benefit, what the dollar math is, what the timeline looks like, and what the worker should look for on each statement.
The transition runs on three triggering events. First, the treating physician declares the worker permanent and stationary — meaning the medical condition has reached maximum medical improvement and is unlikely to change with further treatment. Second, the QME or AME issues an impairment report under California Labor Code §4660 translating the medical findings into an AMA Guides 5th Edition percentage. Third, the PD percentage is calculated using the 2005 PD schedule including the occupational variant, age factor, and any apportionment under California Labor Code §4663. Each event changes which benefit is paying — and most workers see at least one gap between benefits during the transition.
| Factor | Temporary disability (California Labor Code §4653) | Permanent disability (California Labor Code §4658) |
|---|---|---|
| When it starts | 3rd day off work (or 1st day if hospitalized) per California Labor Code §4650. | After the worker is declared permanent and stationary AND the rating is calculated under California Labor Code §4660. |
| Weekly amount | Two-thirds of average weekly wage at injury, subject to statutory min/max set annually by DWC. | Set by the PD schedule — varies with PD percentage and occupational variant. |
| Duration cap | 104 compensable weeks within 5 years of date of injury; certain catastrophic injuries have a 240-week extension. | Number of weeks set by the PD schedule based on rating; 70%+ PD triggers life pension under California Labor Code §4659. |
| What ends it | Return to work, P&S declaration, or the 104-week cap, whichever comes first. | The scheduled number of weeks runs out (or life pension begins for 70%+ PD). |
| Late-payment penalty | Self-imposed 10% increase under California Labor Code §4650; 25% penalty for unreasonable delay under California Labor Code §5814. | Self-imposed 10% increase under California Labor Code §4650; 25% penalty for unreasonable delay under California Labor Code §5814. |
| SJDB voucher interaction (California Labor Code §4658.7) | Not directly affected. | Voucher up to $6,000 available if no regular, modified, or alternative work offered within 60 days of P&S. |
| Life pension (California Labor Code §4659) | N/A. | Triggered at 70%+ PD; continues for life of the worker. |
| Tax treatment | Generally non-taxable federal and California income. | Generally non-taxable federal and California income. |
"Permanent and stationary," or P&S, is the medical determination that a California worker's injury has reached maximum medical improvement — the condition is unlikely to materially change with further treatment under California Labor Code §4600. P&S is declared by the treating physician in a written report, then confirmed (or modified) by the QME under California Labor Code §4062.2 or the AME. P&S does not mean the worker is "fine" — it means the worker is as good as treatment can reasonably make them. P&S triggers the end of temporary disability under California Labor Code §4653 and the start of the permanent disability rating analysis under California Labor Code §4660. The date matters; insurers sometimes argue for earlier P&S to cap TD.
California temporary total disability under California Labor Code §4653 is capped at 104 compensable weeks within five years of the date of injury. The 104 weeks need not be consecutive — a worker who is partially in and out of TD over two years still counts only the weeks TD was actually paid. Certain catastrophic injuries have a longer cap (up to 240 weeks). When the 104-week cap is reached and the worker is not yet P&S, TD ends and there is typically a gap until the rating is calculated and permanent disability under California Labor Code §4658 begins. This gap is one of the most painful moments in many California claims, and one of the most common reasons workers retain counsel.
The permanent disability rating under California Labor Code §4660 starts with the QME or AME's whole-person impairment percentage under the AMA Guides 5th Edition. That percentage is multiplied by the DWC's diminished-future-earning-capacity (DFEC) modifier, adjusted by the worker's occupational variant from the 2005 PD schedule, and further adjusted by the worker's age at the date of injury. Any apportionment under California Labor Code §4663 — non-industrial causes — reduces the net PD percentage. The final percentage determines the weekly PD rate under the schedule and the number of weeks PD is paid under California Labor Code §4658. Workers at 70% or higher receive a life pension under California Labor Code §4659 after the scheduled PD weeks run out.
The Supplemental Job Displacement Benefit voucher under California Labor Code §4658.7 is a separate benefit — up to $6,000 — available to California workers with permanent partial disability whose employer does not offer regular, modified, or alternative work within 60 days of P&S. The voucher pays for retraining at state-approved schools, vocational counseling, and computer or tool purchases related to retraining. The voucher sits on top of PD and is not reduced by California Labor Code §4663 apportionment. A worker who returns to modified duty for at least 12 months typically does not get a voucher.

Tap to call →The clearest way to know which benefit is paying is to look at the dates the check covers and the weekly rate. Temporary disability under California Labor Code §4653 pays two-thirds of the pre-injury average weekly wage. Permanent disability under California Labor Code §4658 pays a different weekly rate set by the PD schedule and varies with the rating. A check at the TD rate after P&S has been declared is a signal to question the insurer — TD generally ends at P&S unless a catastrophic-injury extension applies.
The QME report under California Labor Code §4062.2 (or AME report) is the document that translates the worker's medical condition into a permanent disability percentage under California Labor Code §4660. A worker who has not seen the QME report in writing should request it from counsel or directly from the QME. The report shows whole-person impairment, apportionment under California Labor Code §4663, and the basis for any conclusion. The DWC QME Locator also confirms the QME's identity and specialty.
