Emergency Medicine Billing Services

Why ED Billing Differs

Emergency department billing starts from a different premise than office billing: the patient did not choose the provider, the payer did not approve the visit in advance, and the encounter is leveled on the complexity of the medical decision making alone. Since 2023 the emergency E/M codes are selected on medical decision making, not on history and examination, so the chart has to show the thinking rather than the checklist. Add facility and professional claims moving on separate tracks, observation decisions made at 2 a.m., and out-of-network status that the patient never consented to, and the specialty needs its own medical billing services workflow rather than a general one.

E/M Leveling 99281 to 99285

• 99281 is the one level that may not require the presence of a physician or other qualified health care professional, so medical decision making does not apply to it.
• 99282 requires a medically appropriate history and or examination and straightforward medical decision making. 99283 requires low, 99284 moderate, and 99285 high medical decision making.
• Since the 2023 revision, level is driven by medical decision making alone. Documentation that itemizes history and exam elements without showing the problems addressed, data reviewed and risk of management does not support the level.
• Our coders level from the three medical decision making elements as documented, then check that the diagnosis and the disposition support each other. Leveling is covered in depth under E/M coding.

Prudent Layperson Denials

Payers deny emergency claims retrospectively by arguing the final diagnosis was not an emergency. Florida law defines an emergency medical condition by the presenting symptoms, as a condition manifesting itself by acute symptoms of sufficient severity, which may include severe pain, such that the absence of immediate medical attention could reasonably be expected to result in serious jeopardy to the health of the patient. That is a presenting-symptoms test, not a discharge-diagnosis test, and Florida HMOs may not require prior authorization for emergency services and care. Our appeal packages lead with the triage note, the chief complaint and the vital signs at arrival, because that is what the standard turns on. The workflow runs through denial management.

Out-of-Network and Balance Billing Rules in Florida

• Under Florida Statute 627.64194 the insurer is solely liable for payment to a nonparticipating provider of covered emergency services, in accordance with the coverage terms of the policy.
• The insured is not liable to the nonparticipating emergency provider for anything other than applicable copayments, coinsurance and deductibles.
• The nonparticipating provider may not collect or attempt to collect any excess amount from the insured, directly or indirectly, beyond those cost-sharing amounts.
• An insurer may impose coinsurance, copayment or benefit limits on a nonparticipating provider only if the same requirement applies to a participating provider.
• In practice this means the dispute over the allowed amount is between the group and the plan. Patient statements for out-of-network emergency care are limited to cost sharing, and our patient billing reflects that.

Our ED Billing Process

• Charts are leveled from medical decision making by coders who work emergency medicine only, with the facility and professional claims reconciled so the two tell the same story.
• Prudent layperson denials are tracked as their own denial category and appealed with the presenting-symptom record, not the final diagnosis.
• Out-of-network claims are priced and pursued against the plan under the Florida statute, with patient responsibility held to cost sharing.
• Observation and critical care time are captured from the record so the encounter is not under-billed at the level of the initial visit.
• Monthly reporting shows level distribution, denial rate by payer and days to payment, so the group can see leveling drift before a payer does. This is part of our specialty medical billing program.
