Procedure Overview
This family covers procedures that place a device into one of the veins of the upper body - the arms, neck, chest, or head - without replacing any part of the vein itself. The most common example is placement of a central venous catheter, port, or PICC line into a vessel such as the subclavian, internal jugular, axillary, or basilic vein. These devices stay in the vein to give medications, draw blood repeatedly, deliver chemotherapy or long-term antibiotics, or provide dialysis access, sparing a patient from having a new needle stick every time care is needed.
A clinician chooses this approach when a patient needs reliable, repeated venous access over days, weeks, or months, or when medications are too irritating for a standard peripheral IV. Placement is usually done with ultrasound guidance and confirmed by X-ray to ensure the tip sits in the right location before use begins.
Because the device remains in place after the procedure ends, follow-up visits for flushing, dressing changes, or eventual removal are a separate, related encounter rather than part of this same code.
Anatomy & Axis Detail
Axillary Vein, Left
The left axillary vein carries blood from the arm into the subclavian vein as it crosses the floor of the axilla, running close to the axillary artery and brachial plexus. Its caliber and relatively predictable course make it a workable site for placing venous access devices, dialysis catheters, or pacemaker and defibrillator leads when subclavian or cephalic access is unsuitable, typically approached under ultrasound guidance to limit the risk of pneumothorax and nerve injury. Insertion here means a device such as a catheter, port, or lead is placed into the vein without cutting into or removing any part of the vessel wall, with the device left in position for therapy or monitoring. The left side may be chosen to spare the right for a future device or because left-sided anatomy proves more favorable, so laterality should be documented precisely.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Device: Infusion Device
Infusion Device denotes a device left in place to deliver medication, fluids, or other substances into a body part over time, such as an intrathecal or epidural pump. It is distinct from devices that merely monitor or mechanically support tissue, since its function is ongoing pharmacologic or fluid delivery rather than structural replacement. Common placements include the spinal canal, peritoneal cavity, and vascular access sites.
Coding & Documentation
Coders assign an Insertion code here when documentation describes a device left in the body after the procedure - a catheter, port reservoir, or similar hardware - rather than a temporary tool used and withdrawn. The operative note should identify the specific upper vein accessed (subclavian, axillary, innominate, etc.) and the device type, since the device value in the code depends on whether it is a port, PICC, tunneled catheter, or non-tunneled catheter.
A frequent error is coding the vein where the device physically sits versus the vein through which it was threaded to reach a central location; PCS conventions direct coders to the vessel entered, not the final tip position. Another common miss is failing to capture a separate approach or an additional procedure, such as fluoroscopic guidance, when institutional policy requires it. Missing device-type documentation - port versus catheter versus infusion device - also leads to query generation, since the seventh-character device value cannot be guessed.
Commonly Confused With
Insertion is often confused with Administration procedures, which cover injecting a substance rather than placing hardware; a one-time IV push of contrast or medication is not coded here. It is also distinct from Revision, which applies when an existing device is being corrected or repositioned rather than placed for the first time, and from Removal, which is used only when the device is taken out with no replacement. Central line placement can additionally be confused with Lower Veins insertion when the catheter is threaded from a femoral approach - the body system reflects the vein actually entered, not the vein where the tip ultimately rests.
