ASC vs. Hospital Billing

What’s the real difference in coding, compliance, and reimbursements?

Lets break it down

Billing Meaning

ASC billing covers outpatient surgeries, while hospital billing includes inpatient stays, tests, and complex care procedures.

Coding Differences

ASCs use CPT, HCPCS codes with modifiers like -SG, -73. Hospitals use ICD-10-PCS for inpatient care.

Compliance Matters

ASCs follow ASCQR under CMS; hospitals follow extensive CMS Conditions of Participation with deeper documentation rules.

Reimbursement Gaps

ASCs get 50–60% of hospital rates. Hospitals benefit from OPPS, IPPS, and bundled payment systems.

Administrative Workload

Hospitals face higher compliance and coding audits. ASCs have quicker revenue cycles with fewer billing layers.

Why It Matters

Knowing these differences helps reduce claim denials and optimize reimbursements for both ASCs and hospitals..
