What A2033 covers
A2033 identifies Myriad Morcells measured by mass, with each reported unit representing 4 milligrams. It differs from A2032, which identifies Myriad matrix by square centimeter; select the code that matches the product used and its measurement basis. Record the quantity of Myriad Morcells in milligrams so the submitted unit count reflects the amount represented by the code. CMS classifies A2033 as technical-component-only, with a separate code covering interpretation.
Medicare assigns A2033 carrier-priced status C: it has no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim under the physician fee schedule. Coverage is left to the contractor's judgment. Report one unit for each 4 milligrams; for example, 8 milligrams corresponds to 2 units.
