Top Medicare and all-payer inpatient procedures by ICD-10 code
On January 1, 2023, the Centers for Medicaid and Medicare Services (CMS) released changes made to its list of inpatient-only procedures. Currently, there are approximately 1,700 surgical procedures on the list, with some being added and removed every year. In 2023, CMS removed 11 codes (mostly involving facial and bone reconstruction) and added eight (mostly related to hernia repair).
A major implication of this change is that ambulatory surgery centers (ASCs) and other outpatient care centers can offer these reconstruction procedures, potentially drawing patients and revenue away from more traditional hospital inpatient departments. One factor driving patients to ASCs for procedures is the cost difference.
The following list features the top 25 all-payor and Medicare inpatient procedures by volume, with ICD-10 codes. Raw procedure count numbers have been converted to a percentage share of the top 25 procedures for each category.

Which inpatient-only procedures were performed most in 2023?
Injections, transfusions, and diagnostic tests appeared frequently across both lists, but obstetric and urinary procedures ultimately took the top two spots: “Delivery of Products of Conception, External Approach” and “Performance of Urinary Filtration, Intermittent, Less than 6 Hours Per Day”.
Are ICD-10 codes only for inpatient procedures?
The ICD-10 code set is used for both inpatient and outpatient procedures. The relatively high number of ICD-10 codes compared to previous code sets enables greater coding specificity, which is especially useful for inpatient coding, as inpatient records tend to be more detailed and complex than outpatient records.
