A unique identification number (UIN), provided by CDHA, identifies you as the provider if you submit
oral health claims to the insurance carriers. Only you can use your UIN — it is not transferrable, nor
can it be used by another dental hygienist. Download the UIN Application Form from this page. Once you have completed the application, send it to CDHA. We
will process your application and send you your UIN number.
CDHA-ACHDnet is the network managed by CDHA to transmit electronic claims from independent dental
hygienists to the insurance carriers. It is the only network that is configured to accept dental
hygiene claims.
If you have received your office number from CDHA, please contact your messaging service
directly. If you have not received your office number from CDHA, please contact CDHA at 1-800-267-5235.
The CDHA National Service Codes
are for use by dental hygienists who are practising in an independent dental hygiene
practice. The CDHA service codes are different from the CDA ULS procedure codes.
The National Claim Form
is for the use of dental hygienists who wish to submit a dental hygiene claim from an
independent dental hygiene practice. Dental hygienists who work in dental offices do not typically
submit claims in
their own name.
The full list of carriers that accept dental hygiene claims can be found here.
