CMS: Medical Necessity & Patient Signature Requirements During COVID-19

CMS Clarifies Medicare Requirements Related to Medical Necessity and the Patient Signature Requirement during Current National State of Emergency

By Brian S. Werfel, Esq.

On April 9, 2020, CMS updated its Frequently Asked Questions (FAQs) for billing Medicare Fee-For-Service Claims during the current national state of emergency.  This document includes guidance for numerous industry types, including ambulance services.  The ambulance-specific questions start on page 11.

Two of the more common questions that A.A.A. members have asked during the current crisis are:

  1. Whether the transportation of a patient known or suspected to be infected with the COVID-19 virus would automatically justify medical necessity for the ambulance? And,
  2. Whether CMS will be waiving the requirement that ambulance providers and suppliers obtain the patient’s signature (or an acceptable alternative signature) to consent to the submission of a claim?

CMS did provide some guidance on both of these issues.

CMS addressed the issue of medical necessity in its answer to Question #9 on page 13.  The question posed to CMS was whether an ambulance provider/supplier could consider any COVID-19 positive patient to meet the medical necessity requirements for an ambulance.  CMS responded as follows:

“Answer: The medical necessity requirements for coverage of ambulance services have not been changed. For both emergency and non-emergency ambulance transportation, Medicare pays for ground (land and water) and air ambulance transport services only if they are furnished to a Medicare beneficiary whose medical condition is such that other forms of transportation are contraindicated. The beneficiary’s condition must require both the ambulance transportation itself and the level of service provided for the billed services to be considered medically necessary.”

Basically, CMS declined to offer a blanket waiver of the medical necessity requirements for COVID-19 patients.  In doing so, CMS seems to be suggesting that COVID-19 status, in and of itself, is not sufficient to establish Medicare coverage for an ambulance transport.

Fortunately, CMS did offer specific relief on the Medicare patient signature requirement.  The question posed to CMS on page 16 (Question #14) was whether an ambulance provider/supplier could sign on the patient’s behalf to the extent the patient was known or suspected to be infected with COVID-19, and, as a result, asking the patient (or an authorized representative) to sign the Tablet would risk contaminating the device for future patients and/or ambulance personnel.  CMS responded as follows:

Answer: Yes, but only under specific, limited circumstances. CMS will accept the signature of the ambulance provider’s or supplier’s transport staff if that beneficiary or an authorized representative gives verbal consent. CMS has determined that there is good cause to accept transport staff signatures under these circumstances. See 42 CFR 424.36(e). CMS recommends that ambulance providers and suppliers follow the Centers for Disease Control’s Interim Guidance for Emergency Medical Services (EMS) Systems and 911 Public Safety Answering Points (PSAPs) for COVID-19 in the United States, which can be found at the following link: https://www.cdc.gov/coronavirus/2019-ncov/hcp/guidance-for-ems.html. This guidance includes general guidelines for cleaning or maintaining EMS transport vehicles and equipment after transporting a patient with known or suspected COVID-19. However, in cases where it would not be possible or practical (such as a difficult to clean surface) to disinfect the electronic device after being touched by a beneficiary with known or suspected COVID-19, documentation should note the verbal consent.”

Essentially, CMS is indicating that you can accept a patient’s verbal consent to the submission of a claim in lieu of a written signature.  In these instances, CMS is indicating that the crew must clearly document that they have obtained the patient’s (or the authorized representative’s) verbal consent.
