Court of Appeal restores sanity to workers' comp treatment authorizations

The Second District Court of Appeal recently provided some relief and respite from the hornets' nest that is a claims desk. In Illinois Midwest Ins. Agency, LLC v. WCAB/Rodriguez, the Second District of the California Court of Appeal issued a decision that rejected the prior WCAB holding in Patterson v. The Oaks Farm (2014) 79 CCC 910, a significant panel decision which set forth the burden of the defendant to show a "change of circumstance requirement" before modifying an existing utilization review. This was otherwise referred to as the "Patterson exception." The Rodriquez case is certified for publication and is now citable. 

Sometimes a Court of Appeal will render an opinion that tells the WCAB they should simply read what the Labor Code says. Often, it's not more complicated than that. In Rodriguez, we have such a decision that returns some sensibility to the treatment authorization process. Unfortunately, when a new and significant case comes down, everyone quotes it, but few understand it. 

As many claims' professionals understand, some authorizations seem to go on in perpetuity. For example, a diligent and contentious claims professional will get an RFA (request for authorization) for physical therapy and/or some home healthcare following surgery. That is often quite sensible and rational at the time. However, some of these authorizations seem to go on in perpetuity because the defendant cannot show a change in circumstances. In short, such authorizations often become de facto permanent.

Then the primary treating physician will not report any improvements or progress, and as such, any attempt to modify or rescind prior authorization will result in an expedited hearing and a penalty petition. It's odd how an applicant can receive tens of thousands of dollars--sometimes hundreds of thousands--and it seems to show no improvement or relief. Yet the treatments and invoices roll on. Thus applicants can hold this risk exposure over the defendant until the defendant decides to buy it out.

Applicant attorney's often rely on Labor Code Section 4601(k), which states that a utilization review (UR) can't be revisited within a 12-month period if there is a "material change in the facts." However, under this new finding, a defendant no longer has the burden to demonstrate this change. The UR reviewer may now, under evidence-based medicine, provide rationale for terminating a prior authorization.

Does this mean that Labor Code Section 4601(k) is no longer good law? Not at all. 

Applicants may bring new RFA if circumstances change. They often do--and should--if such a change is warranted. However, this never means that something is always going to be authorized in perpetuity. The rationale that, since it was provided before, it must now be provided without end or even review has come to an end.

Unfortunately, there are some very nefarious actors who will establish an ongoing level of care for which there is no end in sight--and, "imagine that," the applicant never seems to get better until a big settlement is proffered. 

In Rodriquez, the Court of Appeal returned all such decisions back to utilization review and chided the WCAB for their derivation from the Senate Bill (SB) 863, enacted in 2012. One of the aspects of SB 863 was to get the applicant's bar out of the advocacy for medical and lien providers. This was, in part, the basis for establishing the UR under Labor Code 4610. The Court in Rodriguez opined that there is statutory basis for an "ongoing treatment" exception to the UR and independent medical review (IMR) process. Again, the Court directed the WCAB to read the Labor Code. 

In its rationale, the Court of Appeal returns to the concept of rational and evidence-based medicine. UR and IMR remain the controlling standard. 

This does not mean that all ongoing treatment may be halted or should be halted. Naturally, some are claiming the sky is falling and that claims administrators will simply be cutting off treatment. This could not be further from the truth. It simply states that all ongoing treatment will still be subject to utilization review. That was the legislative intent all along. UR and IMR keeps both the applicant and the defendant in check.

In fact, providers must now show a justification for their ongoing treatment and demonstrate the efficacy and benefit to the applicant. If there is no improvement or change in the applicant's condition, some treatments will be discontinued. 

Now, the battle lines are going to be drawn on this, and there are other issues we might see.

For example, we will most likely see more claims of "chronic and progressive" under Labor Code § 5410 & § 5804. The term "chronic and progressive" in California cases generally refers to insidious and progressive diseases where the conditions worsen over time. This generally involves diagnoses such as complex regional pain syndrome, AIDS, industrial cancers, hepatitis and some neurological conditions, such as CTE (chronic traumatic encephalopathy). To that end, some findings and awards or stipulated awards may become risk time bombs for such abuse. With such claimed conditions, most treatment modalities are rarely contained.

On the upside, this is also good news for defendants defending against outrageous lien claims. Good UR and IMR may now trounce some of these outrageous treatment liens. Like a lot of aspects of law, it takes time for players on all sides to come to the realization that the rules apply to all concerned.

Ultimately, this is good news for the whole community. While some will decry the rollback of care, it simply returns medicine to accepted and established medical standards. Applicants will be better served by raising the standards in which treatment is authorized, and defendants will have some relief from scheme that rewards abuse. 

Not all longstanding medical modalities need to be reversed. However, the "free shot of goals" of less than pristine players will now struggle to circumvent and game the system.
