Healthpoint Biotherapeutics today advised that the Centers for Medicare and Medicaid Services (CMS) has eliminated the physician 90-day global surgical period for the application of all skin and dermal substitutes, including OASIS® Wound Matrix and OASIS® Ultra Tri-Layer Matrix. Additionally, the American Medical Association has created eight new CPT® codes that apply to brands in the skin substitute category, resulting in the same Medicare allowable rates for the application of all covered brands of skin and dermal substitutes.
