====== Percutaneous procedure classification ======


The classification of percutaneous procedures depends on the context—clinical (e.g., cardiovascular, neuro, musculoskeletal), procedural goal (diagnostic or therapeutic), or coding systems (e.g., ICD-10-PCS, CPT, SNOMED CT).

1. By Clinical Area
Here’s a general classification by specialty:

Cardiology
Percutaneous Coronary Intervention (PCI) – e.g., angioplasty, stent placement.

Percutaneous valvuloplasty – e.g., for mitral or aortic stenosis.

Percutaneous closure procedures – e.g., ASD, PFO closure.

Interventional Radiology
Percutaneous biopsy – e.g., liver, kidney, bone.

Percutaneous drainage – e.g., abscesses, pleural effusions.

Percutaneous nephrostomy

Percutaneous ablation – e.g., radiofrequency or cryoablation of tumors.



Urology
Percutaneous nephrolithotomy (PCNL)

Percutaneous insertion of ureteral stents

Orthopedics
Percutaneous pinning of fractures

Percutaneous tendon release or repair

2. By Purpose
Diagnostic

Percutaneous needle biopsy

Percutaneous aspiration (e.g., of cysts or fluids)

Therapeutic

Percutaneous catheter drainage

Percutaneous tumor ablation

Percutaneous implantation (e.g., pacemaker leads, spinal cord stimulator electrodes)

3. By Coding (ICD-10-PCS Example)
In ICD-10-PCS, percutaneous procedures are defined by:

Approach: “3” = Percutaneous (via skin or mucous membrane, using instrumentation)

For example:

02703ZZ: Dilation of Coronary Artery, One Artery, Percutaneous Approach

0JH60XZ: Insertion of infusion device into subcutaneous tissue, percutaneous approach
