After the usual April 1 update, the Centers for Medicare & Medicaid Services (CMS) released revised versions of Hospital Outpatient Prospective Payment System (OPPS) Addendum A and Addendum B.
Addendum A includes OPPS ambulatory payment classifications (APCs) along with information such as status indicators and payment rates. Addendum B shows OPPS payment by CPT® or HCPCS Level II code.
The data from these revised files is now available on Codify by AAPC to users whose accounts include this data. The effective date for this new data is April 1, 2022.
