Ventilator Management vs. E/M Codes:

This Guide Helps You Make the Call

Boost reimbursement by 70% on subsequent care days with 9400x in lieu of low-level E/M.

Prolonged ventilation is on the rise, due, in part, to improved intensive care unit survival. Brush up on your ventilator management coding skills to ensure that you don't miss out on deserved reimbursement when dealing with this growing area of respiratory medicine.

Time and Place Define Ventilator Management Options

Start by knowing the four choices you have for reporting ventilator management and the rules governing each.

Hospital care: Code ventilator management for inpatients in the hospital setting by the day using one of the following codes:

• 94002 -- Ventilation assist and management, initiation of pressure or volume preset ventilators for assisted or controlled breathing; hospital inpatient/observation, initial day

• 94003 -- ... hospital inpatient/observation, each subsequent day.

Long-term care: If the pulmonologist is providing ventilator management services in a long-term care facility, report 94004 ( ... nursing facility, per day) for each day she provides care.

Important: For 94002-94004, Medicare requires a face-to-face encounter between the reporting physician and the patient to report ventilator management, says Alexander White, MD, MS, FCCP, of the department of pulmonary and sleep medicine at New England Sinai Hospital in Stoughton, Mass.

There is no specific time requirement the pulmonologist must meet to report  94002-94004; however, the physician should still note in the patient's chart the time he spent providing the service, notes Becky Zellmer, CPC, MBS, CBCS, medical billing and coding supervisor for SVA Healthcare in Milwaukee.

Weigh Choice Between Ventilator Management and Hospital Care

You cannot report ventilator management codes in conjunction with any E/M code (99201-99499) on the same day. So it pays to know which code achieves maximum potential reimbursement when your pulmonologist performs both ventilator management and E/M services on the same day.

Example: The pulmonologist treats a newly admitted patient for acute respiratory failure (518.81). Since initial inpatient care of ventilated patients involves more than the initiation of mechanical ventilation, set aside ventilator codes in favor of a high-level E/M code such as 99223 (Initial hospital care, per day, for the evaluation and management of a patient ...) or, potentially, a critical care code (more on that later).

According to the 2009 Medicare Physician Fee Schedule, 99223 is reimbursed at $180.33, a payment which better reflects the encounter's complexity. The initial day of vent management (94002) earns the provider only $87.64.

Caveat: If the physician is providing only ventilator care and no other medical care, then ventilator management codes only should be used, states White, co-author of "Prolonged Mechanical Ventilation: Review of Care Settings and an Update on Professional Reimbursement," in the February 2008 edition of CHEST (Vol. 133, No. 2).

Using the ventilator management code for subsequent care (94003), however, can pay off when a ventilated patient has stable or resolving medical conditions. It may be more advantageous to bill ventilator management in a patient who would otherwise just require the lowest-level hospital follow-up code, says White.

Example: When the patient's condition and current treatments include management of the ventilator, the physician may opt for 94003 (subsequent day of ventilator management) to achieve a payment of $63.48, instead of 99231 (Subsequent hospital care, per day, for the evaluation and management of a patient ... Physicians typically spend 15 minutes at the bedside and on the patient's hospital floor or unit) and its corresponding payment of $37.15.

How to decide: If the main service is checking and adjusting the vent settings, use a ventilator code, says Denae M. Merrill, CPC, CEMC, HCC coding specialist for The Coding Source and owner of Merrill Medical Management in Saginaw, Mich. On the other hand, if the pulmonologist performs ventilator management during the course of a more extensive E/M visit and the E/M components could support a higher-level code, you may want to go with an E/M code to reflect the more comprehensive service with increased reimbursement, she sums up.

Don't Pass Up Critical Care Reimbursement

Missing an opportunity to report critical care services can mean your practice misses out on well-deserved earnings.

When a patient suffers, for instance, from hemoptysis (786.3), severe sepsis (995.92), or shock (639.5), and requires critical care to manage the critical illness or injury in addition to ventilator management, report one of the following critical care codes (as long as the documentation demonstrates the critical condition and all coding requirements are met):

• 99291 -- Critical care, evaluation and management of the critically ill or critically injured patient; first 30-74 minutes, or

• +99292 -- ... each additional 30 minutes (List separately in addition to code for primary service).These codes reflect the provision of complex services and, as a result, are reimbursed at higher levels than either E/M codes or ventilator management codes, relates White.

It breaks down like this:

• 99291 (initial 30-74 minutes of critical care) earns $212.07,

• +99292 (each additional 30 minutes of critical care) is reimbursed at $106.04, while

• an initial day of ventilator management (94002) earns only $87.64.
