Not supported by the records: what it means and what to do
A reviewer looked at what was sent and didn't see enough to justify the service. Often the deciding record, like a photo of a crack or a periodontal chart, wasn't included.
- “Not dentally necessary”
- “Documentation does not support the service”
- “Radiographs do not support”
What to check first
- What records went with the claim.
- Whether a photo, chart or narrative shows what the X-ray couldn't.
What to do
Appeal with the missing records and a short explanation of what they show.
Stop it next time
Send photos, charts and a narrative with the first claim for crowns and deep cleanings.
Next steps
- Appeal letter: crown denied as not needed
- Billing guide: crowns
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.
