BackgroundThe incidence of skin cancer is increasing significantly, and many people have declared the increase an epidemic. It was estimated that 900,000 to 1.2 million cases of nonmelanoma skin cancer occurred in the United States in 1994. With increasing pressure to deliver cost-effective medical care, physicians must understand the cost and value of the various methods to treat skin cancer.ObjectiveOur purpose was to define the true cost of treating a series of skin cancers with the Mohs micrographic technique and compare our costs with calculated estimates of the costs to treat the same cancers with traditional methods of surgical excision.MethodsA group of 400 consecutive tumors was selected. The cost of treatment in the reference group included diagnosis, Mohs micrographic surgery, reconstruction (if applicable), follow-up, and the cost to treat disease recurrence. These costs were then compared with traditional methods of surgical excision: excision with permanent section margin control, excision with frozen section margin control, and excision with frozen section margin control in an ambulatory surgical facility. For cost comparisons, it was assumed that all tumors in the comparison groups would be excised with standard surgical margins and the resultant surgical defects would be reconstructed with the simplest method possible. The costs of diagnosis, excision, pathology, reconstruction, and the cost to treat disease recurrence were then calculated and compared with the costs of treating the lesions with Mohs micrographic surgery.ResultsOur calculation of costs documents that Mohs micrographic surgery is similar in cost to office-based traditional surgical excision and less expensive than ambulatory surgical facility-based surgical excision. The average cost of Mohs micrographic surgery was $1243 versus $1167 for excision with permanent section margin control, $1400 for excision in the office with frozen section margin control, and $1973 for excision with frozen section margin control in an ambulatory surgical facility. Analysis based on anatomic location yielded similar results.ConclusionMohs micrographic surgery is a method of surgical excision with high intrinsic value that is cost-effective in comparison to traditional surgical excision.
