Blood collection tube, vacuum, for dialysis, per 50

HCPCS code

Name of the Procedure:

Blood Collection Tube, Vacuum, for Dialysis, per 50 (HCPCS Code: A4770)


This procedure involves the use of vacuum blood collection tubes specifically designed for dialysis patients to safely and efficiently draw blood samples. These tubes help ensure the accurate measurement of various blood parameters and are typically utilized in batches of 50.


Medical Conditions or Problems Addressed:
  • Chronic Kidney Disease (CKD)
  • End-Stage Renal Disease (ESRD)
  • Regular monitoring in patients undergoing dialysis ##### Goals or Expected Outcomes:
  • Accurate and efficient blood sample collection
  • Monitoring and management of kidney function and dialysis adequacy
  • Early detection of potential complications related to dialysis


Symptoms or Conditions Warranting the Procedure:
  • Patients undergoing regular dialysis
  • Requirement for routine blood tests to monitor various blood parameters, including electrolytes, hemoglobin, and infection markers ##### Patient Criteria:
  • Individuals diagnosed with chronic or end-stage renal disease
  • Patients scheduled for hemodialysis or peritoneal dialysis


Pre-procedure Instructions:
  • No specific fasting required unless concomitantly scheduled with other tests needing fasting
  • Patients may be advised to continue or temporarily adjust their usual medications based on physician guidance ##### Diagnostic Tests or Assessments:
  • Prior blood work to determine baseline values
  • Routine health check-up to ensure patient stability for sample collection

Procedure Description

  1. Step 1: The patient’s arm is prepared by cleaning the site with antiseptic.
  2. Step 2: A sterile needle is inserted into an accessible vein.
  3. Step 3: The vacuum blood collection tube is attached to the needle to draw the blood.
  4. Step 4: Multiple tubes can be filled if necessary, each sealing automatically upon reaching the required volume.
  5. Step 5: The needle is removed, and the site is covered with a bandage. ##### Tools, Equipment, or Technology Used:
    • Vacuum blood collection tubes designed for dialysis
    • Sterile needles and antiseptics ##### Anesthesia or Sedation Details:
    • Generally not required for standard blood draws


The blood collection process typically takes about 5-10 minutes.


The procedure is usually performed in:

  • Dialysis centers
  • Outpatient clinics
  • Hospitals


  • Trained nurses or phlebotomists
  • Dialysis technicians
  • Occasionally, supervising nephrologists

Risks and Complications

Common Risks:
  • Minor bleeding or bruising at the puncture site ##### Rare Risks:
  • Infection at the needle site
  • Hematoma formation ##### Management:
  • Applying pressure post-needle removal to minimize bruising
  • Keeping the site clean and monitoring for signs of infection


Expected Benefits:
  • Accurate blood work results essential for effective dialysis management ##### Realization Time:
  • Immediate results for routine monitoring; specific test results may take longer based on laboratory processing times.


Post-procedure Care:
  • Keep the bandage on for a few hours
  • Monitor the site for signs of excessive bleeding or infection ##### Expected Recovery Time:
  • Immediate; patients can resume normal activities right after ##### Follow-up Appointments:
  • Based on regular dialysis schedule and any additional physician recommendations


Other Treatment Options:
  • Finger-stick blood tests (less invasive but limited in the volume and types of tests available) ##### Pros and Cons of Alternatives:
  • Finger-stick tests are less painful but not suitable for all required tests in dialysis patients

Patient Experience

During Procedure:
  • Mild discomfort at the needle insertion site
  • Minor pain or pressure sensation as blood is drawn ##### After Procedure:
  • Minimal to no pain
  • Proper management techniques and following guidelines can ensure comfort and reduce any potential pain or complications.
