A rule that decides appeals

Network gap: when no in-network provider can do it

If the plan's network has no provider with the needed expertise within a reasonable distance or time, you can ask for a network-gap (single-case) exception so the out-of-network provider is paid at the in-network level; marketplace plans are also held to network adequacy standards. The request works best before the care, with the evidence that you looked.

When it applies

  • Specialised surgery, rare-disease care, paediatric subspecialties, gender-affirming care, complex cancer surgery where the network is thin
  • HMOs and EPOs with no out-of-network benefit, where the exception is the only path

Where it does not

  • Preference for a particular out-of-network clinician when a qualified in-network one is available
  • Plans with a robust out-of-network benefit already covering the care

The sentence to put in the appeal

I request a network-gap exception to receive [service] from [provider] at in-network cost-sharing. The plan's network does not include a provider who [performs this procedure / treats this condition / can see me within a clinically appropriate time] within [distance], as documented below. Marketplace plans must maintain a network sufficient in number and type of providers under 45 CFR 156.230; where the network cannot provide the covered service, the plan must arrange it at in-network cost.

Replace the bracketed parts with your facts. Cite the regulation exactly as written; quote the plan’s own wording next to it.

How to use it

  1. Step 1

    Document the search

    Names, dates and answers from in-network providers you contacted; wait times; distances.

  2. Step 2

    Have the referring clinician write

    Why the specific expertise is needed and why the in-network options are not equivalent.

  3. Step 3

    Get the answer in writing before the care

    A verbal 'we will cover it' is not an authorisation. Ask for the exception letter.

Worked example

A complex jaw surgery had no in-network oral surgeon within 150 miles. The family submitted the search log and the surgeon's letter; the plan approved the out-of-network surgeon at in-network rates before the procedure.
