Coding & Billing

This document is a personal quick-reference guide compiled for educational and informational purposes only. It summarizes selected CPT codes, wRVU values, and billing concepts relevant to pulmonary and critical care practice, drawn from publicly available sources including the CMS Physician Fee Schedule. 

It is not official coding, billing, legal, or compliance advice, and does not represent the policies of any hospital, employer, or payer. Codes, wRVU values, and payer rules change frequently and vary by institution. Users are solely responsible for independently verifying all codes against current CMS/AMA sources and for following their own institution's coding and compliance protocols, which supersede anything in this document. Direct questions to your institution's coding/compliance department.
