Key Alliant Health Plans billing terms

Alliant Health Plans writes dental, medical coverage in GA. This page draws on 69 indexed Alliant Health Plans policy documents; every figure quoted below is linked back to the document it came from, and nothing is asserted that a source cannot support.

Payer ID

The electronic routing number that identifies Alliant Health Plans to a clearinghouse. Submitting a claim with the wrong payer ID is one of the most common causes of a claim never reaching the payer at all - it rejects at the clearinghouse rather than denying, so it may never appear in your denial queue.

Timely filing limit

The window, counted from the date of service, within which Alliant Health Plans will accept an initial claim. Filing past the limit is one of the few denials with no clinical defense - the claim is denied on receipt regardless of medical necessity. Limits differ by plan type and by whether you are in-network, so a single number rarely covers every Alliant Health Plans product.

Prior authorization

Approval obtained from Alliant Health Plans before a service is rendered. Requirements vary by CPT/HCPCS code, place of service, and plan. A service performed without a required authorization is typically denied as a provider write-off, meaning the balance usually cannot be billed to the patient.

Appeal deadline

The window for disputing a Alliant Health Plans determination, counted from the remittance date rather than the date of service. Missing it usually forecloses the appeal entirely, so the deadline is worth calendaring the day the remittance posts.

How to verify Alliant Health Plans coverage before you bill

1. 1

   Confirm eligibility and the specific plan

   Alliant Health Plans is a payer, not a single benefit design. Coverage rules, prior-authorization lists, and filing windows differ across its commercial, Medicare Advantage, and Medicaid products. Verify which plan the member actually holds before applying any rule you looked up.

2. 2

   Find the coverage policy for the exact code

   Coverage is decided per CPT/HCPCS code, not per procedure name. Search the Alliant Health Plans policy for the specific code you intend to bill, including the modifier where one changes the coverage story.

3. 3

   Check whether prior authorization is required

   Authorization requirements are code-and-place-of-service specific, and they change. Confirm the requirement for the date of service you are billing, not the date you are checking.

4. 4

   Run the code pair through NCCI edits

   Before billing two codes together, check the NCCI Procedure-to-Procedure edit and the Medically Unlikely Edit unit cap. A bundling edit that is not resolved with an appropriate modifier produces a denial that looks clinical but is purely a coding-edit problem.

5. 5

   Document medical necessity against the policy's own criteria

   When a policy lists coverage criteria, the documentation should address those criteria in the policy's own terms. An appeal grounded in the payer's published policy is materially stronger than one arguing general clinical merit.

6. 6

   Submit inside the filing window and calendar the appeal date

   Track the filing deadline from the date of service and, once a remittance posts, the appeal deadline from the remittance date. Both are absolute in a way clinical arguments are not.

Why Alliant Health Plans claims get denied

The themes below are the ones that drive most A/R work. Each links to the CARC code that carries it on the remittance.

• Missing or invalid information — CO-16

  The claim reached Alliant Health Plans but could not be adjudicated as submitted - a missing modifier, an incomplete field, or a required attachment. These are usually correctable and resubmittable rather than appealable.

• Prior authorization absent — CO-197

  The service required authorization that was not obtained, or the authorization on file does not match the code or date billed.

• Not medically necessary under the policy — CO-50

  Alliant Health Plans applied a coverage policy and concluded the documentation did not meet its criteria. This is the denial most often overturned on appeal, because the argument is against a published standard you can read and answer point by point.

• Bundling and code-pair edits — CO-97

  The code is considered part of another service billed the same day. Resolvable when an NCCI modifier genuinely applies, and not when it does not.

• Filed past the deadline — CO-29

  The claim arrived after the filing window closed. Rarely recoverable absent documented proof of timely submission.

• Wrong payer or member not covered — CO-109

  The claim went to Alliant Health Plans but the member's benefits sit elsewhere on that date of service - a different carrier, a different contractor, or a plan that had already terminated. Usually a front-desk eligibility problem rather than a billing one.

• Another payer should pay first — CO-22

  Coordination of benefits puts a different carrier in the primary position. The claim generally has to be worked through the primary payer before Alliant Health Plans will consider it.
