Infectious disease specialists can generate surprise bills when they consult at in-network hospitals, and unlike emergency medicine physicians and several other specialties, they receive no protection from the No Surprises Act. Specialists typically hold their own insurance contracts separate from the hospital's, so a facility in your network may have consulting specialists who are not. Out-of-network specialists at in-network hospitals charge significantly more than their in-network counterparts at the same facilities. Understanding when infectious disease consultation creates billing risk—and what your legal protections actually cover—helps you catch these charges before they arrive.

When Infectious Disease Consultations Trigger Out-of-Network Bills
hospital admissions frequently involve consultations from specialists you did not select. A 2016 Health Care Cost Institute analysis found that 14.5% of hospital admissions involved at least one out-of-network professional claim, with rates varying dramatically by state (1.7% in Minnesota to 26.3% in Florida).
When you are admitted to an in-network hospital, the facility may call in an infectious disease specialist—for example, if you develop a hospital-acquired infection or have a condition requiring antibiotic stewardship guidance—without confirming their network status first. The consultant's bill arrives separately from the hospital bill, often weeks later, because physicians and hospitals negotiate with insurers independently.
The hospital's contract with your insurer does not bind the specialists it calls. This separation means your insurance paperwork shows the hospital as in-network and the specialist as out-of-network, making the surprise bill seem like an error when it follows from how physician networks actually work.
Why the No Surprises Act Does Not Protect You
The No Surprises Act, effective January 1, 2022, prohibits balance billing for emergency care and eight named specialties: emergency medicine, anesthesia, pathology, radiology, laboratory services, neonatology, hospitalist, and intensivist. Infectious disease is not on this list.
That omission leaves you exposed to out-of-network charges when an infectious disease specialist consults on your care, even if the initial hospitalization is at an in-network facility. The protected specialties were chosen because they are most frequently called in emergency situations where patients cannot negotiate in advance. Infectious disease consultation, though often medically urgent, typically happens after admission and after the decision to go to a specific hospital has already been made—a gap in the law's logic that nonetheless leaves you with the bill.
What Out-of-Network Infectious Disease Bills Typically Cost
Out-of-network specialists at in-network hospitals charged an average of 798% of Medicare rates, compared to 297% for in-network specialists at the same facilities, according to a Yale School of Management study. While that data came from emergency physicians, the pricing pattern holds across specialties operating outside their contracted networks. An individual surprise bill from any unprotected specialist might range from several hundred to several thousand dollars, depending on the complexity of the consultation, the number of visits, and the specialist's pricing. The markup is not a billing error—it reflects the specialist's allowed rate in the out-of-network universe, which operates under different fee schedules than in-network contracts.
How to Reduce Your Risk Before Admission
If you are facing planned hospitalization or know you may need it, call ahead and ask the hospital to identify which specialists are in your network and which you may be assigned. Request in-network specialists when possible, or ask for written confirmation of network status before any consultation occurs. This conversation is harder to have for emergency admissions, but worth having for scheduled procedures.
When an infectious disease specialist is called during your stay, ask the hospital's billing office or patient advocate whether that physician is in-network. Some hospitals track this; others cannot answer until after the service occurs. Even a verbal confirmation gives you documentation for a later dispute.
If You Receive a Surprise Bill
Request an itemized bill and verify that the service was actually rendered. Confirm the charges against your hospital records and the dates of your admission. Contact your insurance company and report the claim as a surprise bill—most insurers have a separate dispute process for out-of-network charges that should have been prevented or flagged in advance.
Ask the specialist's office whether they participated in an in-network contract you may have missed, or whether you qualify for a hardship discount. If the bill is correct and the specialist is genuinely out-of-network, you can negotiate the amount; many practices accept reduced payment rather than send the account to collections. Document every conversation in writing (email confirmations) so you have a record of your dispute if it escalates.
Frequently Asked Questions
Can I be sued if I do not pay a surprise bill?
Yes, you can be sued or the debt sent to collections. However, you can dispute the bill with your insurer and negotiate directly with the provider. Paying in full signals you accept the charge, so do not pay it while contesting it.
Is there a law that prevents this?
The No Surprises Act protects you from balance billing by emergency specialists and eight other named specialties, but infectious disease is not one of them. You do have the right to an itemized bill and to dispute the charge.
Can I refuse care from an out-of-network specialist?
In an acute situation, refusing medically necessary care is not practical. After the fact, you can dispute the bill and request a reduced rate, but you cannot retroactively reject care already rendered.
