Silvana Toska was playing in a grass field with her daughters late last fall when she felt a sting on her ankle. The family had come to listen for barred and great horned owls as the sun set on a large park near their Davidson, North Carolina, home.

It was “just like a mosquito bite, nothing major, and I just scratched it,” said Toska, a political science professor. Then she began to itch everywhere.

She couldn’t see anything in the dark, so her husband shined his phone light on her. Because she also felt pressure in her chest, the family quickly went to an urgent care clinic.

A doctor there recognized she was experiencing anaphylactic shock , a life-threatening, fast-moving allergic reaction. The doctor rushed her to a room without checking her in, saw her blood pressure was low, and administered two epinephrine injections and IV fluids, Toska said.

The itching stopped, and the tightness in her chest went away.

Clinical Editorial

Case summary and presenting event

Silvana Toska developed a rapid systemic allergic reaction after a sting while walking in a park with her children.

She became diffusely itchy and experienced chest tightness.

Her family took her to an urgent care clinic, where the clinician identified anaphylaxis, measured low blood pressure, administered two epinephrine injections and intravenous fluids, and determined that she required emergency department (ED) observation.

The urgent care clinician arranged ambulance transport to the nearby hospital ED.

Clinical care delivered in the ED

On arrival at Atrium Health Lake Norman, Toska was seen briefly by an ED physician and had an IV line that had been placed at the urgent care continue to be used for medication administration.

The ED record shared with KFF Health News indicates the ED physician documented providing 90 minutes of personal “critical care.” During the ED stay, a nurse administered additional medication through the IV, and Toska received a dose of famotidine.

The physician returned after approximately 90 minutes, reviewed vital signs, discussed the allergic reaction and home precautions, and the patient was discharged.

The total ED observation time described by the patient was roughly one and a half hours; the physician also noted that monitoring for at least two hours is standard practice for anaphylaxis.

Billing charges and patient financial responsibility

Atrium Health billed the insurer, Blue Cross Blue Shield of North Carolina, $6,746.50 for the ED encounter.

The billed items cited in the report included $20.60 for famotidine and $6,445.60 attributed to “critical care” charges.

The hospital applied two current procedural terminology (CPT) codes for critical care: CPT 99291 (described in the report as the code applied for 30–74 minutes) and CPT 99292 (for an additional 30-minute increment).

Because Toska had not met her deductible, her out-of-pocket responsibility was the $150 ED copay plus $3,100.24 of the billed charges, which she reported as her personal financial obligation.

Rationale cited for critical care coding

The article notes that the CPT coding framework defines critical care as direct physician management of a patient for a minimum of 30 minutes who has a probability of imminent or life-threatening deterioration.

The ED note reportedly documents that the physician provided 90 minutes of direct critical care.

The American College of Emergency Physicians’ coding guidance, referenced in the report, identifies anaphylactic shock as an indication for code 99291.

The ED physician and external emergency medicine commentary cited monitoring for at least two hours after anaphylaxis because symptoms can recur or progress; the article quotes an emergency medicine chair describing that some patients may require escalation to intensive care while others will not.

Contextual points and operational details from the source

Toska’s urgent care clinician initiated definitive therapy for anaphylaxis (epinephrine and IV fluids) and arranged ambulance transfer for continued observation.
In the ED, the attending physician’s direct contact with the patient was described by Toska as brief, with ongoing nursing care and IV medication administration during the stay.
The hospital’s billing applied critical care codes that substantially comprised the billed ED charge total.

Limitations and gaps in the available reporting

The source does not provide the hospital’s internal justification or contemporaneous documentation beyond the physician’s note that 90 minutes of critical care were delivered.
The insurer’s adjudication details (for example, whether the billed critical care charges were accepted, reduced, or contested) are not reported.
The article does not present independent clinical documentation to corroborate the precise timing, content, or intensity of physician bedside interventions during the recorded 90-minute period beyond the patient’s account and the ED visit note excerpts shared.
No broader claims-data or comparative pricing analysis is included in the source; this is a single-patient billing narrative.

Implications raised by the report

The case highlights how application of high-level ED billing codes for critical care can drive large charges after an emergency presentation for anaphylaxis.
The account draws attention to the interplay of urgent care stabilization, ED observation/monitoring practices for anaphylaxis, and resulting patient financial exposure when deductibles are unmet.

Open questions for further investigation (not answered in the source)

How the hospital’s charge description and coding aligned with payer policy and whether the insurer processed or adjusted the billed critical care charges was not reported.
Whether additional documentation existed to support the physician’s 90-minute critical care claim, beyond the brief interactions described by the patient, was not provided.
