Beneficiary counts apply to one code at a time. A patient who received two of these codes is counted under both, so the column cannot be added up into a number of people. Rank is each code's position among all 7,889 CPT codes billed to Medicare in CY2021, so the column skips a number wherever a code we don't yet cover sits.

Which codes bring in the most Medicare money? Copy link

Spending is heavily concentrated. The top 25 codes carry 56.6% of the $83.0B these 500 codes account for.

  1. 1 99214 Long Follow-Up Office Visit $12.0B
  2. 2 99213 Routine Follow-Up Office Visit $6.6B
  3. 3 99232 Daily Hospital Visit $2.7B
  4. 4 99233 Extended Daily Hospital Visit $2.6B
  5. 5 66984 Cataract Surgery $2.0B
  6. 6 99204 Long New Patient Office Visit $1.9B
  7. 7 99215 Longest Follow-Up Office Visit $1.9B
  8. 8 99223 Extended Hospital Admission Visit $1.8B
  9. 9 99285 Emergency Visit, Highest Urgency $1.6B
  10. 10 97110 Physical Therapy Exercises $1.5B

Why the most common codes aren't the most expensive Copy link

Rank the same 500 codes by patients and then by dollars, and the two lists disagree. A cheap service given to millions and a costly one given to thousands can land far apart depending on which question you ask.

What this data covers—and what it doesn't Copy link

These are CY2021 Medicare fee-for-service totals at the national level. Medicare Advantage, Medicaid and commercial volume are excluded, so real-world use of every code here runs higher than the numbers show.

Beneficiary counts belong to a single code. Summing that column would count the same patient once for every code they received, so this page never totals it or calls it a patient count.

The shortlist covers numeric CPT codes. Drug codes and HCPCS Level II are left out on purpose. Drug codes are billed per unit, which makes service counts incomparable, and HCPCS Level II codes already carry CMS-owned descriptions.

16 codes on this list have since left the fee schedule. They were billed heavily in CY2021 before CMS deleted them, so their links point at the last quarter that priced them rather than at a page that no longer exists.

How the ranking is built Copy link

A code's overall position is its best standing across two measures: unique beneficiaries served and total allowed dollars. Ranking on either one alone buries half the story—beneficiaries favor cheap high-volume tests, dollars favor expensive procedures. Sort the table by a single measure to see each view on its own. The ranking spans all 7,889 CPT codes billed to Medicare in CY2021; this table shows the top 500 we cover.
