# Where do I verify Iowa Medicaid dental — Dental Wellness Plan and Hawki?

> At secure.deltadentalia.com or providers.dentaquest.com — both checked in DNS on 10 September 2026. Since 1 July 2026 the Dental Wellness Plan and Hawki dental benefit has run through two carriers: Delta Dental of Iowa and DentaQuest. MCNA's contract ended. Its portal still resolves in DNS so the dead contract does not announce itself.

Iowa dental — the **Dental Wellness Plan** and **Hawki**, the state's children's programme — runs through **two** carriers as of **1 July 2026**: Delta Dental of Iowa at **secure.deltadentalia.com**, and DentaQuest at **providers.dentaquest.com**. Which of the two you use is a property of the patient's coverage, not of the state, so there is no single Iowa answer to memorise. What there is, is a date.

## The contract that ended is the one that will cost you a morning

**MCNA's Iowa contract ended.** Delta Dental of Iowa and DentaQuest replaced it from 1 July 2026. That is the whole of the change, and it is the fact an office cannot work out by looking — because nothing about a retired contract looks retired from the outside.

We checked. On 10 September 2026, **portal.mcna.net still resolved in DNS**, through an Amazon load balancer to three addresses. A hostname that has been taken out of a state's dental programme does not stop existing. The name stays in DNS, so a bookmark saved in Iowa in June still points at a host that is there, and nothing in the address bar tells you the Iowa contract behind it has ended. The failure arrives later and in the wrong shape — as an eligibility answer that does not match, or a claim that goes nowhere — long after the person who typed the address has moved on to the next patient.

This is the opposite of a dead-hostname failure, and it is worse. A hostname that has been switched off fails immediately, loudly, in the browser, and you go looking for the new one that afternoon. A hostname that has merely lost this state's contract fails quietly and much later.

## What the DNS lookups actually showed

Every hostname was put through a Domain Name System lookup on 10 September 2026. That is what was verified and the limit of it: no sign-in was attempted, and no claim is made that any of these sites was reachable from a particular office network. Portals routinely refuse traffic that does not look like an ordinary browser, so a connection that fails from elsewhere says nothing about the portal.

- **secure.deltadentalia.com** resolved to four addresses. The bare **deltadentalia.com** resolved to the same four, so the two names sit on the same infrastructure — but type the `secure.` name, because that is the one the programme publishes.
- **providers.dentaquest.com** resolved through an Akamai chain to two addresses. Note the word: `providers`, plural. DentaQuest also publishes `provideraccess.dentaquest.com`, which resolves to a completely different pair of addresses, and other states use that one. Iowa's is `providers`.
- **portal.mcna.net** resolved, as above. Resolving is not the same as being your payer.

## Where you actually log in

| What | Address | Checked |
|---|---|---|
| Delta Dental of Iowa | secure.deltadentalia.com | 10 September 2026 |
| DentaQuest | providers.dentaquest.com | 10 September 2026 |
| MCNA — contract ended | portal.mcna.net still resolves and is no longer your route | 10 September 2026 |

## What to do

- **Delete the MCNA bookmark for Iowa patients.** It still opens. That is the problem, not the exception.
- **Ask which of the two carriers holds the patient's dental** before you verify — the Dental Wellness Plan and Hawki both route by carrier now.
- **Check the DentaQuest hostname character by character.** `providers.dentaquest.com` and `provideraccess.dentaquest.com` are different systems, and a colleague in another state will hand you the wrong one in good faith.
- **Write "two carriers since 1 July 2026" against Iowa in your practice management system**, so the next person does not re-derive it from a stale note.
- **Re-check anything last verified before July 2026.** A verification taken under the old contract was taken from the wrong payer.
