Units exceed the acceptable maximum
The units billed are more than the payer allows for this code in one day (medically unlikely edit).
Usual causes
- Unit math error (minutes instead of units, milligrams instead of billing units).
- Legitimate high units without the modifier or documentation the payer needs.
The fix
Recalculate the units. If they were correct and clinically needed, split the lines with the appropriate modifier where rules allow, or appeal with documentation. Otherwise send a corrected claim.
Appeal or corrected claim?
Corrected claim for errors; appeal with records when the units are right.
Deadline to watch
Timely filing or appeal window.
Exact limits are in your payer contract or provider manual. When in doubt, send the correction or appeal this week.
