Code history

Was this code valid on the date of service, and what did it map to under the model that paid that year? 10 code sets, FY2018 through FY2027.

How to use this page

Whether a code was valid on the date of service, and what it mapped to under the model that paid that year.

  1. Paste the codes, and give the date of service if you have one.
  2. The code set turns over on 1 October, so a date in October, November or December belongs to the NEXT fiscal year — 4 November 2021 is FY2022. The page does that conversion for you.
  3. The verdict block answers the date directly. The table below it shows every year loaded, so you can see when a code arrived, when it went, and when its wording changed.
  4. The change log flags what matters in a review: new, deleted, reworded, billable status, and any move between HCCs within the same model.

What this page does not do

  • A year with no model files loaded reads "no model loaded", never "maps to nothing". Those are different facts and only one of them is about the code.
  • HCC movement is compared within a model. The V24 to V28 changeover is a change of model, not a change to the code, and is not reported as one.
  • It reports what the published files say. Whether a code belonged on that claim is answered by the documentation.
