More information needed: what it means and what to do
The claim wasn't decided on its merits. The reviewer needs records to judge it: X-rays, a periodontal chart, photos or a short narrative.
- “Additional information requested”
- “X-rays required”
- “Narrative required”
- “Periodontal charting required”
What to check first
- Exactly what the explanation of benefits or letter asks for.
- The deadline for sending it, if one is given.
What to do
Send the records asked for, with the claim number, as soon as possible. This is not an appeal; it's finishing the claim.
Stop it next time
Attach X-rays and a narrative to the first claim for crowns, buildups, deep cleanings and other services that need them.
Next steps
- Billing guide: deep cleaning (scaling and root planing)
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.
