Colorectal Cancer Screening denials in California external review
In the California DMHC record, independent physician reviewers decided 18 published external-review cases involving colorectal cancer screeningand overturned the plan’s denial in 38.9%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.
Most-fought treatments for colorectal cancer screening
| Category | Decisions | Overturned |
|---|---|---|
| Colonoscopy | 4 | 50% |
| Monitored Anesthesia Care | 3 | 0% |
| Cologuard | 3 | 66.7% |
What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 13 | 30.8% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 5 | 60% |
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for Cologuard stool testing for evaluation of the enrollee, who underwent routine colon cancer screening. Findings: 2/3 of the physician reviewers found that the physician reviewer found colorectal neoplasms shed DNA in the stool. The DNA can be isolated and tested for the presence of mutations and epigenetic changes acquired during carcinogenesis. Cologuard is a second generation stool DNA test. Cologuard has been approved by the U.S. Food and Drug Administration as a screening test for colorectal carcinoma to be followed, when abnormal, by diagnostic colonoscopy. This test may be appropriate for asymptomatic patients, 50 to 84 years of age, who are at average risk for colorectal cancer. This patient is a high risk for sedated colonoscopy due to her extensive neurologic history.
Nature of Statutory Criteria/ Case Summary: The enrollee has requested coverage for CT colonoscopy. She has a history of hypothyroidism, migraines, basal cell skin cancer, pre-diabetes mellitus, osteopenia, and appendectomy. She had a sigmoidoscopy that was negative and the plan was for a repeat procedure in five years. The enrollee had a gastroenterology consult for screening colonoscopy and reported a bad reaction to anesthesia in the past with nausea, agitation and not feeling normal for more than a day. Computed tomographic (CT) colonography (also virtual colonoscopy or CT colography) is an option for colorectal cancer (CRC) screening in asymptomatic average-risk individuals, over the age of 50 years.
Where the denial was upheld
The patient is a 55-year-old male who was referred by his provider for a screening colonoscopy in February 2005. The patient has no prior history of a screening colonoscopy and no prior history of a failed attempt or unsuccessful colonoscopy. The patient underwent a CT colonography (virtual colonoscopy) instead of a conventional optical colonoscopy, which revealed a normal appearing colon and two left renal calculi. At issue is whether the virtual colonoscopy was medically necessary for evaluation of the patient’s medical condition.Virtual colonoscopy represents a noninvasive test for the examination of the colonic lumen that involves the generation of both two-dimensional and three-dimensional views of the colon and rectum using data derived from computed tomography.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for virtual colonoscopy/computed tomography colonography of the abdomen and pelvis. Findings: The physician reviewer found that the American College of Radiology (ACR) guidelines for virtual colonoscopy states that the indications for a computed tomography colonography examination include “screening examination in individuals who are at average or moderate risk for developing colorectal carcinoma.” The U.S.

Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed.
