Physician On-Call Policy: EMTALA Duties, Pay, and Liability

A physician on-call policy is the written document a Medicare-participating hospital uses to satisfy the Emergency Medical Treatment and Labor Act’s requirement that specialists be available to evaluate and stabilize emergency patients. It names who is on the list, sets response expectations, addresses compensation within federal fraud and abuse limits, and describes what happens when someone fails to appear. Getting it wrong is expensive: inflation-adjusted civil penalties now reach $136,886 per violation for hospitals with 100 or more beds, and the same amount applies to an on-call physician who refuses to respond.¹

What EMTALA Requires the Policy to Cover

Any hospital with an emergency department that accepts Medicare must provide a medical screening examination to anyone who requests care, regardless of insurance or ability to pay, and must either stabilize an emergency medical condition or arrange an appropriate transfer.² To make that possible, the hospital must maintain a list of on-call physicians, including specialists, who can come in and provide stabilizing care after the initial ED evaluation.

The implementing regulation at 42 CFR 489.24 goes further. It requires the hospital to have written policies covering situations where a specialty is not available and situations where the on-call physician cannot respond due to circumstances beyond their control.³ The policy is not optional paperwork. It is the mechanism CMS uses to judge whether the hospital’s coverage system is real.

Duties of the On-Call Physician

The policy should distinguish two obligations. The first is availability for consultation: being reachable by phone or pager throughout the scheduled period so the ED can call for advice. The second is responsiveness: physically arriving at the hospital when the treating ED physician decides in-person specialist care is needed. Both duties are bounded by the scope of the physician’s existing medical staff privileges.

CMS guidance allows an on-call physician to send a licensed non-physician practitioner, such as a physician assistant, to appear and provide assessment or stabilizing treatment on the physician’s behalf, subject to state scope-of-practice laws, hospital bylaws, and the patient’s clinical needs. The on-call physician remains ultimately responsible for the patient. And if the ED physician disagrees with sending a representative and specifically requests the on-call physician in person, the on-call physician has to come in. Failing to do so after being requested exposes both the physician and the hospital to EMTALA sanctions.⁴

There is a protection for the ED physician on the other side of the call. If the on-call specialist fails to appear within a reasonable time, the treating ED physician may order a transfer without being personally penalized. The penalty falls on the hospital and on the specialist who did not show.²

Setting Response Times

There is no federally mandated number of minutes. CMS uses the phrase “reasonable period of time” and leaves each hospital to define it, while strongly recommending that maximum response times be set in writing and communicated to on-call physicians.⁵

In practice, most hospital policies require a return phone call within 15 to 30 minutes and an in-person appearance within 30 to 60 minutes, with the exact window varying by location and specialty. The instruction from CMS is essentially procedural: pick a number, write it down, and enforce it.

Community Call Plans

Hospitals that cannot maintain full specialty coverage alone may participate in a community call plan under which multiple hospitals in a geographic area share on-call responsibilities. The regulation requires the plan to define which hospital covers which specialties and when, describe the geographic area, be signed by an authorized representative of each participating hospital, and coordinate with local EMS protocols so ambulances know where to route patients. Participating hospitals must reassess the plan annually.³

A community call plan does not relieve any participating hospital of its core EMTALA duties. If a patient walks into a hospital that is not the designated specialty facility that night, that hospital still has to provide the screening exam and stabilizing treatment within its own capability before transferring.

Compensation Rules the Policy Has to Respect

On-call pay usually takes one of three forms: a fixed stipend for being available, a fee-for-service structure that pays only when the physician is called in, or a hybrid of the two. High-acuity specialties with frequent callbacks, such as neurosurgery and interventional cardiology, tend to command higher stipends because the burden of availability is heavier. Whatever the model, two federal laws constrain the numbers.

Stark Law

The Physician Self-Referral Law prohibits physicians from referring Medicare patients for certain designated health services to entities with which they have a financial relationship, unless an exception applies. On-call compensation creates that relationship. To fit an exception, the compensation must reflect fair market value and be commercially reasonable. CMS defines fair market value as the price that would result from bargaining between informed parties who are not in a position to generate business for each other, and commercially reasonable as an arrangement that furthers a legitimate business purpose and makes sense given the parties involved.

Anti-Kickback Statute

The federal Anti-Kickback Statute makes it a felony to knowingly offer, pay, solicit, or receive anything of value to induce referrals for services covered by federal healthcare programs, with penalties of up to $100,000 and up to 10 years in prison.⁶ On-call payments that exceed fair market value can look like disguised inducements, which is why the FMV analysis carries weight. The compensation should track the actual burden of the call: how often the physician gets called in, typical patient acuity, and the opportunity cost of holding the schedule open.

Payments from an employer to a bona fide employee are explicitly excluded from Anti-Kickback Statute liability. Employed physicians receiving on-call pay through their employment agreement therefore face less regulatory risk than independent contractors receiving stipends under separate on-call agreements.⁶

When On-Call Time Counts as Hours Worked

For employed physicians, the Fair Labor Standards Act regulation at 29 CFR 785.17 draws the line based on how restricted the physician’s freedom is during the on-call period. A physician who must remain on the hospital’s premises, or so close that they cannot use the time for their own purposes, is working. A physician who merely needs to be reachable by phone is generally not.⁷

Courts examine the totality of restrictions: geographic limits, required response speed, callback frequency, and whether calls are so disruptive that the physician cannot do much else. A 20-minute response requirement with rare callbacks reads differently from a 10-minute response requirement with hourly calls. Most physicians qualify for the FLSA’s learned professional exemption and are not entitled to overtime, but residents, fellows, and some employed hospitalists may not meet the exemption criteria, making the compensability of their on-call time a live question.

Penalties and Liability When Someone Fails to Respond

The statute sets the base civil monetary penalty at up to $50,000 per violation for both the hospital and any responsible physician, with a $25,000 cap for hospitals with fewer than 100 beds.² After annual inflation adjustments, the maximum is now $136,886 per violation for hospitals with 100 or more beds and $68,445 for smaller hospitals, with physicians facing the same adjusted amounts.¹ If the violation is gross, flagrant, or repeated, the physician can also be excluded from Medicare and Medicaid.

Federal penalties are only the floor. On-call services agreements typically require EMTALA compliance and include specific response-time terms; a hospital that incurs investigation costs or pays penalties because a physician did not appear may be able to recover those amounts from the physician under the contract. State medical malpractice law can also apply if a patient is harmed by the delay, depending on whether the on-call arrangement created a physician-patient duty of care.

Making the Policy Work in Practice

Scheduling should be equitable. The American College of Emergency Physicians has stated that on-call requirements must apply to all physicians to ensure equity among medical staff, which in practice means not concentrating call on newer or less politically connected physicians.⁸ The policy should describe how the schedule rotates and how disputes are resolved.

Documentation matters as much as the rules. Hospitals should keep records of on-call schedules and actual response times, because a CMS investigation will turn on whether the hospital had a physician listed and whether that physician was contacted.

Enforcement is where policies commonly weaken. ACEP has acknowledged that penalty systems for untimely responses are difficult to enforce because hospitals fear that disciplining on-call physicians will drive them off the call list entirely.⁸ The tension is real, but the regulatory obligation does not bend to it. A policy the hospital will not enforce invites the six-figure penalties the policy was written to prevent.
