The Spinal Surgery Second Opinion and the Utilization Review Clock
A 38-year-old certified nursing assistant has an accepted lumbar injury from a resident transfer. Her treating physician requests a two-level lumbar fusion with instrumentation. The request arrives at the claims administrator on a Monday with a complete 10-page report, MRI, and two epidural steroid injection records. The adjuster refers it to utilization review (UR) the same day. UR is performed by a board-certified orthopedic surgeon who has never treated the injured worker and who reviews only the documents submitted. On day 12, UR modifies the request to a single-level fusion. The treating physician objects and requests an independent medical review (IMR) and a second opinion. The employer's nurse case manager believes the MRI shows only a single-level pathology. The injured worker is 38 with no comorbidities.
1. Did UR comply with the timelines and was the modification permissible? Explain the standards.
Read the worked answer
UR must be timely: under the Labor Code and the UR regulations, a request for a non-urgent, non-emergency service must be reviewed and the decision communicated within five working days of receipt, with a possible extension of up to 14 days if additional information is needed and the extension is timely noticed. Here the request arrived Monday and UR issued on day 12, which is outside the five-working-day window and without evidence of a noticed extension. A late UR decision means the request is deemed approved by operation of law. As to substance, UR may modify a request only when the modification is supported by the medical record and is not a denial of the requested service; modifying a two-level fusion to one level is a denial of the second level and must be supported by substantial evidence, not the reviewer's personal preference. The reviewer's lack of a treating relationship is fine; the lack of a documented basis for the level reduction is the problem.
2. What happens to the treating physician's objection and the IMR request, and what is the adjuster's next step?
Read the worked answer
The treating physician's objection to the UR modification triggers the IMR process. IMR is decided by an independent reviewer who applies the medical treatment utilization schedule (MTUS) and is binding on the parties. However, because the UR decision was untimely, the adjuster should treat the original two-level request as approved and authorize it, which moots the IMR on the level question but does not eliminate the physician's right to object to any remaining modified elements. The adjuster's next step is to document the receipt date and the UR decision date, issue an authorization for the requested two-level fusion, and notify the physician and facility. The adjuster should also open a file note on the UR vendor's late decision because repeated violations create penalty and reporting exposure, and should not rely on the nurse case manager's MRI interpretation, which is not a UR determination.
3. The surgery is authorized and performed. Six months later the treating physician requests a second surgery at the same level. How should the adjuster treat a new UR request?
Read the worked answer
A new request for a second surgery at the same level is a new request for authorization and must go through UR again; the prior authorization does not carry forward to a different procedure or a changed clinical picture. The adjuster should confirm the request is complete, route it to UR the day it is received, and calendar the five-working-day deadline with a documented extension if records are missing. Because the request involves the same body part and a prior authorized fusion, the reviewer should have the operative report and any new imaging. If UR denies and the physician objects, the IMR decision is binding. The adjuster should also evaluate whether the second surgery is reasonably required given the first, and reserve for potential permanent disability if the physician eventually declares the worker permanent and stationary.
