HMO out-of-network claims

Why "out of network" is a big deal in an HMO

A health maintenance organization is built around a contracted delivery network. Under Texas Insurance Code Chapter 843 an HMO is authorized to arrange or provide basic health care services to its enrollees through participating physicians and providers. That design has a hard edge: when an enrollee walks into an office or facility that has no contract with the HMO, the visit is normally outside the benefit plan and outside the HMO's ordinary claim-payment machinery.

So the producer's job is to explain the narrow doors through which a non-network claim still gets paid.

The doors that make a non-network claim payable

• Emergency care. Chapter 843 defines emergency care in terms of the patient's condition — a medical condition of recent onset and sufficient severity that a prudent layperson would believe immediate care is needed to avoid serious jeopardy to health, serious impairment of a bodily function, or serious dysfunction of a body organ or part. Nothing in that definition turns on whether the treating provider signed a network contract.
• HMO authorization or referral. If the enrollee's care is arranged, referred, or authorized by the HMO — including situations where the network cannot supply a medically necessary covered service — the claim is handled as a plan benefit rather than as a self-referred out-of-network visit.
• Verification or preauthorization. Chapter 843 lets a physician or provider get a determination from the HMO before services are rendered. Once the HMO has verified or preauthorized services, it is bound by that determination and cannot simply reverse course at claim time.
• Continuity of care. When a provider contract ends, Chapter 843 contemplates continued coverage of ongoing treatment for a limited period, so care that was in-network yesterday does not become the enrollee's whole problem tomorrow.

If none of those doors is open, out-of-network care generally is not a covered HMO benefit, and the enrollee can be exposed to the provider's full charges.

The claim clock

Subchapter J of Chapter 843 is the Texas prompt-pay law for HMO claims. Three numbers drive it:

1. 95 days — the deadline for a physician or provider to submit the claim after providing the service.
2. Clean claim — the claim must contain the required data elements before the payment clock runs.
3. 30 / 45 days — the HMO must pay, deny, or audit a clean claim by the 30th day if it was filed electronically and by the 45th day if it was filed non-electronically. Pharmacy claims run on a shorter 21-day track. Missing those deadlines exposes the HMO to statutory penalties, and the same duties follow any entity the HMO contracts with to process or pay claims.

One nuance producers get wrong: those statutory deadlines are written for participating physicians and providers. Never promise a non-contracted provider the identical 30/45-day statutory turnaround — for a non-network claim, timing and payment level depend on the emergency/authorization posture and the plan documents.

What the enrollee owes

When the HMO is responsible for the claim, the enrollee's exposure is the plan's cost sharing — copayment, coinsurance, deductible — not the provider's billed charge. Chapter 843's provider-contract requirements keep participating providers from billing the enrollee for covered services beyond that cost sharing. Out-of-network, that shield is weaker, which is exactly why emergency-care and authorization rules matter so much to a Texas HMO enrollee.
