Critical Care Guidelines - CPT 99291 and 99292

Critical care is the direct delivery by a physician(s) or other qualified health care professional of medical care for a critically ill or critically injured patient.

A critical illness or injury acutely impairs one or more vital organ systems such that there is a high probability of imminent or life-threatening deterioration in the patient's condition. 

Critical care services include the treatment of vital organ failure or prevention of further life-threatening conditions. 

Delivering medical care in a moment of crisis and in time of emergency is not the only requirement for providing Critical Care services.

Examples of vital organ system failure include, but are not limited to,

  • Central nervous system failure, 
  • Circulatory failure, 
  • Shock, 
  • Renal, hepatic, metabolic, and/or respiratory failure. 

Critical care may be provided on multiple days, even if no changes are made in the treatment rendered to the patient, provided that the patient's condition continues to require the level of attention mentioned above.

Key Points

The Critical Care Services for a patient who is not critically ill but happens to be in a critical care unit are reported using other appropriate E/M codes.

Critical care and other E/M services may be reported to the same patient on the same date by the same individual.

The critical care code is applicable for a critical care service provided for the first 30 – 74 minutes. Any Critical Care service provided for less than 30 minutes should be billed with the appropriate level of E/M code.

Usually, a Critical Care service is provided to a patient in a "Critical Care Area" such as,
  • Coronary Care Unit (CCU), 
  • Intensive Care Unit (ICU), 
  • Respiratory Care Unit, or 
  • Emergency Room.

Usage of CPT Index - Instructions

The alphabetic index is not a substitute for the main text of the CPT codebook. Even if only one code is present, the coder must refer to the main term to ensure that the code is selected accurately and correctly to identify the services rendered. Main Terms The index is organized by main terms. Each main term can stand alone or can be followed by up to three modifying terms. There are four primary classes of main entries, Procedures or Services - E.g, Scopic, Anastomosis, Splint, Opening Organ or Other Anatomical Site - E.g, Knee, Arm, Ear, Tibia, Colon Conditions - E.g, Abscess, Entropion, Tetralogy of Fallot. Synonyms, Eponyms, and Abbreviations. - ECG, EEG, PET, Brock Operations, Clagett Procdures Modifying Terms The main term may be followed by up to three indented terms that modify the terms they follow. EG. The main term "Endoscopy" is subdivided by the anatomical sites in which the procedure is used. And within these anatomical sites, the specific purpose of the pr

Additional Information About Modifiers

Sequencing of modifiers  How can that be if the modifiers used were accurate?  There is an order to reporting modifiers and there are three categories that modifier usage fall under:  1. Pricing  Pricing modifiers are always sequenced “before” payment modifiers and/or location modifiers.   The only exception to this rule is when a global surgery package is involved.  For example, you would code modifier 58 first and modifier 82 second in a global surgery.  A few examples of pricing modifiers are: 22, 26, 50, 52, 53, 62, 80, and P1-P6.   2. Payment   Payment modifiers alert the insurance carrier that there is a special situation within the claim  Some examples of payment modifiers would be: 24, 25, 51, 57, 58, 59, 76, and 78.  3. Location  Examples of location modifiers are: E1-E4, FA, F1-F9, LC, LD, LT, RT, RC, TA, and T1-T9.  The general order of sequencing modifiers is ( 1) pricing (2) payment (3) location. Location modifiers, in all coding situations, are coded “last”.  If you code

Evaluation and Management (E/M) Services - Domiciliary or Rest Home Environment

Domiciliary, Rest Home, or Custodial Care Services CPT codes 99324 - 99337 Domiciliary, Rest Home (e.g. Boarding Home), or Custodial Care Services, are used to report E/M services to individuals residing in a facility which provides room, board, and other personal assistance services, generally on a long-term basis.  These codes are also used to report E/M services in an assisted living facility. The facility’s services do not include a medical component. A home or domiciliary visit includes a patient History, Physical Examination and Medical Decision Making in various levels depending upon a patient’s needs and diagnosis.  The visits may also be performed as counseling and/or coordination of car, when medically necessary outside the office environment and are an integral part of a continuous of the patient's care.  The patients seen may have chronic conditions, may be disabled, either physically or mentally, making access to a traditional office visit very difficult, or may have l
