Colon Surgery Coding Center

Last reviewed: June 2026

The Colon Surgery Coding Center organizes procedure-specific coding education into one hub. Start with the procedure family, then move into CPT selection, modifier issues, global-period concerns, documentation requirements, and related wRVU resources.

Right Colectomy

Right Colectomy coding should begin with the operative indication and the actual work performed. The documentation should support approach, anatomy, laterality when relevant, complexity, implants or mesh when relevant, and whether additional services are separately reportable.

• Identify the primary procedure and adjacent code family.
• Check whether add-on codes, component work, or imaging guidance are bundled.
• Document findings that affect medical necessity or modifier use.
• Link the case to related Academy, modifier, source, and documentation resources.
