Official Description

Therapeutic apheresis; for red blood cells

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Therapeutic apheresis is a medical procedure that utilizes a specialized blood processing machine to separate blood into its various components, which include white blood cells, red blood cells, platelets, and plasma. This separation is achieved based on the weight of the different blood components. The primary purpose of therapeutic apheresis is to remove a specific component of the blood that is contributing to a disease state, thereby alleviating the patient's condition. Prior to the procedure, a physician conducts a thorough evaluation of the patient to determine the necessity for therapeutic apheresis. The procedure typically involves the use of a previously placed central venous catheter, or alternatively, venous catheters may be inserted to facilitate the connection of blood tubing to the apheresis machine. The physician is responsible for determining the specific parameters for the apheresis process and programming the machine accordingly. Once initiated, blood is drawn from the patient and enters the apheresis machine through one of the venous catheters. The machine then separates the blood into its components, removes the targeted component that is causing the disease, and returns the remaining blood components back to the patient's body through a second catheter. Throughout the procedure, the physician closely monitors the patient, which may include cardiac monitoring and pulse oximetry to ensure patient safety. After the procedure is completed, the patient is disconnected from the machine and undergoes a re-evaluation to assess their condition.

1. Indications

The indications for performing therapeutic apheresis for red blood cells include the following:

  • Red Blood Cell Disorders Conditions such as sickle cell disease or hereditary spherocytosis where the removal of red blood cells may be necessary to manage symptoms or complications.
  • Autoimmune Hemolytic Anemia Situations where the body produces antibodies against its own red blood cells, necessitating their removal to improve the patient's condition.
  • Transfusion Reactions Instances where a patient experiences adverse reactions to blood transfusions, requiring the removal of incompatible red blood cells.

2. Procedure

The procedure for therapeutic apheresis for red blood cells involves several critical steps:

  • Patient Evaluation The physician conducts a comprehensive evaluation of the patient to determine the need for therapeutic apheresis, considering the patient's medical history and current condition.
  • Catheter Placement A central venous catheter may be utilized if previously placed; otherwise, venous catheters are inserted to establish access for the procedure. Blood tubing is then connected to these catheters and the apheresis machine.
  • Machine Programming The physician sets the apheresis parameters and programs the blood processing machine according to the specific needs of the patient and the procedure.
  • Initiation of Apheresis The apheresis process is initiated, during which blood is drawn from the patient through one of the venous catheters into the apheresis machine.
  • Separation of Blood Components Inside the apheresis machine, the blood is separated into its various components based on weight. The targeted red blood cells, which are contributing to the disease state, are removed from circulation.
  • Return of Blood Components The remaining blood components, which are not contributing to the disease, are returned to the patient's body through a second catheter, ensuring that the patient maintains adequate blood volume and circulation.
  • Monitoring Throughout the procedure, the physician monitors the patient’s vital signs, which may include cardiac monitoring and pulse oximetry, to ensure safety and address any potential complications.
  • Completion and Re-evaluation Upon completion of the apheresis procedure, the patient is disconnected from the machine, and a re-evaluation is performed to assess the patient's condition and response to the treatment.

3. Post-Procedure

After the therapeutic apheresis procedure, patients may require monitoring for any immediate side effects or complications. It is essential to assess the patient's vital signs and overall condition to ensure stability. Patients may experience mild side effects such as dizziness or fatigue, which should be addressed promptly. Follow-up evaluations may be necessary to determine the effectiveness of the procedure and to plan any further treatment if required. Additionally, the physician may provide specific post-procedure care instructions, including hydration and activity restrictions, to support the patient's recovery.

X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
