CO-60
Outpatient services not covered within a period before/after inpatient services
What This Code Means
Charges for outpatient services aren’t separately payable because they fall within the payer’s inpatient bundling window.
Common Causes
- Outpatient service rendered within 72 hours (or payer-defined window) before an inpatient admission
- Related diagnosis ties the outpatient visit to the subsequent admission
How to Resolve or Appeal
- Confirm the payer's bundling window (often 3-day rule for Medicare)
- Bill as part of the inpatient claim if bundling applies
