CPC Certification Review Training with Legacy

Overview

  • Designed to assist in passing the CPC certification exam.
  • Not for beginners; prior understanding of the coding process is required.

Focus Areas

  • Surgical procedures in the 30,000 series of codes.
    • Respiratory system
    • Cardiovascular system
    • Hemic and lymphatic systems
    • Mediastinum and diaphragm

Respiratory System

  • Anatomy: Critical for code selection.
    • Structures include lungs, diaphragm, mediastinum, etc.
  • Mediastinum: Central chest area separating lungs, containing heart, vessels, trachea, etc.
  • Diaphragm: Main breathing muscle, separates chest and abdominal cavity.

Lymphatic System

  • Part of the immune system, transports lymph fluid with lymphocytes.
  • Functions in removing toxins, waste, and unwanted materials.
  • Spleen: Filters blood, part of immune function.

Diagnostic Codes

  • Vaping health problems are in Chapter 22.
  • Diaphragmic herniation: Congenital or acquired, diagnosed with imaging tests.

Coding Tips

  • Codes in respiratory section usually unilateral unless specified.
  • Modifiers: Append modifier 50 for bilateral reporting.
  • Rhino (nose) surgeries and procedures.

Surgical Procedures

  • Turbinates: Removal when diseased.
  • Rhinectomy: Partial or total nose removal.
  • Rhinoplasty: Usually cosmetic repair of the nose.
  • Septoplasty: Corrects nasal septum deformities.

Endoscopy and Excision Procedures

  • Differences between open and endoscopic approaches.
  • Larynotomy and larynectomy procedures.

Chest and Lung Procedures

  • Thoracostomy, thoracotomy, pneumonia ostomy and their purposes.
  • Decortication: Removal of scar tissue on lungs.

Cardiology

  • Heart Anatomy and Function
    • Four chambers, myocardium, pericardium, and electrical conduction system.
  • Blood Flow: Right atrium, ventricle through pulmonary artery to lungs and back to left side.
    • Pulmonary artery: Deoxygenated blood to lungs; pulmonary vein: Oxygenated blood to heart.

Cardiac Conditions and Procedures

  • Myocardial infarction: Heart attack, different types and related coding.
  • Hypertension and related diseases.

Devices and Surgeries

  • Pacemakers and ICDs: Used to regulate heart rhythm.
  • Coronary artery bypass graft (CABG): Bypass blocked coronary arteries.
  • Central venous access devices for quick bloodstream access.

Interventional Radiology

  • Minimally invasive techniques using imaging guidance.
  • Hemodialysis and portal decompression explained.
