What N362 means

The number of days or units billed is higher than the payer accepts for this service.

Payers set limits on how many units of a code they will pay per day or per claim, or how many days they will cover. N362 means the claim went over that ceiling, so some or all units were denied.

It usually supports a reason code such as 119 or 151. Often the fix is to check how the code defines a unit rather than to appeal.

Common causes

• Units were billed in the wrong measure, such as minutes instead of time blocks or milligrams instead of billing units.
• The service exceeded the payer's daily unit limit.
• Units for several days were added up on one line.

What to do next

1. Check the code's unit definition and the payer's unit limit for it.
2. Recalculate units from the documentation and correct the claim if needed.
3. Split lines by date of service if several days were combined.
4. Appeal with records if the higher units were medically necessary and allowed by policy.
