When Does a Claim Move From Temporary to Permanent Disability?
The transition generally occurs when the medical condition becomes permanent and stationary, also called maximum medical improvement. That does not mean the worker is symptom-free or no longer needs treatment. It means the condition has stabilized enough for the doctor to evaluate lasting impairment, work restrictions and future medical needs.
The permanent-and-stationary report is therefore one of the most important documents in the claim. It should accurately identify the industrial body parts, history, examination findings, impairment, restrictions, causation, apportionment and future medical recommendations.
The Doctor’s WPI Number Is Not Always the Final PD Rating
Rating rule: For injuries on or after January 1, 2013, Labor Code section 4660.1 directs permanent disability rating to account for the nature of the physical injury or disfigurement, occupation and age. The medical whole-person impairment is a critical input, but it is not always the same as the final permanent disability percentage.
| Step | What happens |
|---|---|
| Medical evaluation | Treating physician, QME or AME describes impairment, restrictions, causation, apportionment and future medical needs. |
| Rating | The medical findings are converted into a permanent disability rating under California’s rating rules, including age and occupation factors. |
| DEU / adjudication | The Disability Evaluation Unit may issue formal, consultative or summary ratings in qualifying settings; disputed cases can proceed through the workers’ compensation adjudication process. |
| Benefits / resolution | The rating and other claim issues inform statutory PD payments and settlement discussions, but future medical rights and job-displacement issues require separate analysis. |
What Can Make a Permanent Disability Report Unreliable or Incomplete?
- an injured body part or accepted diagnosis is omitted;
- the doctor does not have an accurate history of the job duties or injury mechanism;
- work restrictions are vague or inconsistent with the examination;
- impairment analysis is not adequately explained;
- apportionment is asserted without an adequate medical explanation;
- future medical care is not addressed;
- important diagnostic studies or surgical records were not reviewed; or
- the report contains a factual error that changes the analysis.
A rating dispute can therefore be a medical-report problem, a mathematical/rating problem or both. The correct response depends on where the error originates.
Partial Disability and 100% Permanent Total Disability Are Different Categories
Most permanent disability awards are partial. A 100% permanent disability rating is permanent total disability. DWC states that permanent total disability benefits are paid for life at the temporary disability rate, subject to applicable statutory adjustments. Severe injury, inability to return to the old job and a 100% rating are not interchangeable concepts.
For injuries on or after January 1, 2013, Labor Code section 4660.1 preserves the possibility of permanent total disability and sets the rating framework for permanent partial or total disability. A serious claim should be evaluated on the actual medical and rating evidence rather than marketing language such as “maximum benefits.”
Permanent Disability and Future Medical Care Must Be Reviewed Separately
PD compensates for legally recognized permanent impairment. Future medical treatment is a separate right. DWC describes two common workers’ compensation settlement structures: a Compromise and Release, which generally resolves specified claim rights for a lump sum, and Stipulations with Request for Award, which can preserve future medical treatment for the accepted injury.
A worker should understand what is being closed before deciding that a lump-sum number is favorable. The value and practical consequences of future medical care can be especially important after surgery, chronic medication, injections, rehabilitation, prosthetics or anticipated follow-up treatment.
Los Angeles Disability Evaluation and DWC Resources
The DWC Los Angeles district office is currently listed at 320 W. 4th Street, 9th Floor, Los Angeles, CA 90013-1954 and includes a Disability Evaluation Unit and Information & Assistance Unit. DWC’s DEU evaluates medical descriptions of impairment and prepares formal, consultative and summary ratings in different settings.
Use DWC’s current ZIP-code and DEU locators for filing or rating requests rather than assuming every Los Angeles County matter belongs at the same office. Agency addresses and procedures should be rechecked at launch.
What to Bring to a Permanent Disability Review
- permanent-and-stationary / maximum-medical-improvement report;
- QME or AME reports;
- DEU or other permanent disability rating documents;
- all permanent disability payment notices;
- temporary disability payment history;
- current work restrictions and job description;
- written modified-duty or return-to-work offers;
- future medical recommendations;
- surgery and diagnostic records relevant to lasting impairment;
- SJDB voucher documents, if any; and
- any proposed Compromise & Release or Stipulations papers.
Frequently asked questions
Can I receive permanent disability if I returned to work?
Yes. California DWC states that a worker may receive PD benefits even after returning to work. Permanent disability addresses lasting impairment, not simply whether the worker is currently off work.
Is a 20% whole-person impairment automatically a 20% permanent disability rating?
Not necessarily. The medical impairment is an input into the California rating process; the final PD percentage can differ because the rating system also applies statutory factors such as age and occupation.
What if I disagree with the doctor’s permanent disability report?
The next step depends on whether the dispute concerns medical findings, impairment, apportionment, future care or the rating calculation, and whether the worker is represented. QME/AME and DEU procedures can apply in different settings.
Does permanent disability pay all future lost wages?
No. DWC states that PD benefits are limited and may not replace all future income loss. Workers’ compensation also does not pay ordinary pain-and-suffering damages.
Should I settle future medical care at the same time as permanent disability?
That is a separate decision. A settlement can affect future medical rights, so the medical recommendations and likely long-term needs should be reviewed before signing a C&R or other resolution.
