What was disputed, and how it came out
Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.
The WCAB found that the dispute was over the reasonable value of Dr. Nathan's services and thus subject to Independent Bill Review, not WCAB jurisdiction, rescinding the WCJ's decision.
From the decision · page 2Based on our review of the record and applicable law, we find merit in defendant's contention that the WCAB lacks jurisdiction over this dispute because its essence is the reasonable value of Dr. Nathan's services, not coding or the rectitude of defendant's EORs as suggested by the WCJ. We also conclude that it is appropriate to allow this matter to proceed to IBR. Accordingly, we will rescind the WCJ's decision and replace it with a decision reflecting the above conclusions.
The facts that decided it
What the panel treated as outcome-determinative, and which side it favoured.
Defendant issued three Explanations of Review (EORs) with varying payment amounts, demonstrating the dispute was over the reasonable value of Dr. Nathan's services.
Favours Defendant prevailed
This showed the essence of the dispute was payment amount, not coding or procedural compliance, leading to IBR jurisdiction.

Evaluated applicant and provided a medical-legal report billed under ML-104 code.

(8 CCR Section 10451.1(f)(1)(A)(i).) The [WCJ] finds that since the defendant did not serve any [EORs] that complied with Labor Code Section 4603.3, [defendant] waived all objection to the billing and that the matter is subject to the non-IBR process under 8 CCCR Section 10451.1(c)(1).

If the provider fails to request an independent bill review within 30 days, the bill shall be deemed satisfied, and neither the employer nor the employee shall be liable for any further payment.
