At issue were fees paid for a procedure called a 3D CT reconstruction, similar to these scans used to examine a 4,000 year old mummy.

The professional association representing Nova Scotia doctors is praising the provincial government for its decision to drop a complaint against more than two dozen radiologists.

On Dec. 6 the Department of Health and Wellness quietly dropped billing complaints filed against 27 radiologists — about one in five of every radiologist licensed in Nova Scotia.

"We commend government for this decision, it's what we've been asking for months," Barbara Johnson, a spokesperson for Doctors Nova Scotia  said in a statement to CBC News about the case.

The complaint was filed with the College of Physicians and Surgeons of Nova Scotia after an audit by Medical Services Insurance (MSI).

At issue were fees paid for a procedure called a 3D CT reconstruction. The complaint alleges unethical billing took place and was filed by then Deputy Minister of Health Kevin McNamara.

Doctors Nova Scotia said the billing arrangement had been accepted without objection for many years before the MSI audit and the Department of Health complaint to regulators.

"We believe this issue highlights the ambiguity that exists and the need for a fair, open and transparent audit and appeal process and clearer billing and reporting," Johnson wrote to CBC News.

The Health Department referred inquiries to Health Minister Leo Glavine, who was unavailable for comment.
