Alternate benefit applied: what it means and what to do
The plan paid as if a cheaper treatment had been done, such as a silver filling instead of a tooth-colored one on a back tooth. It still pays something; the patient owes the difference.
- “Benefit based on alternate procedure”
- “Least expensive alternative treatment applied”
- “Paid as amalgam”
What to check first
- Whether the plan's documents have an alternate benefit (least expensive alternative) clause for this service.
- Whether there was a clinical reason the cheaper option wouldn't work, such as an allergy. Note it in the records.
What to do
Usually the patient owes the difference between the fee and what the plan paid. Appeal only with a documented clinical reason.
Stop it next time
Quote the alternate benefit up front for posterior tooth-colored fillings and similar services.

Insurers word these differently, and many print a numbered reason code too. Read the words on the explanation of benefits; they say which of these it is.
