Anaesthesia service for Z491, Z492, Z493, Z494, Z495, Z496, Z497, Z498, Z499, Z555 or Z580. This code replaces the listed basic units and time units for anaesthesia for these procedures.

When to Use

Use E032C when providing deep sedation or general anaesthesia for a colonoscopy (Z491-Z499, Z555) or flexible sigmoidoscopy (Z580) performed by another physician.
Use this code specifically when the anaesthesia service requires a level of care beyond procedural sedation, which is not eligible for E032C.

Common Pitfalls

Billing E032C when the proceduralist is the same physician providing the anaesthesia, which is strictly prohibited under same-day restrictions.
Attempting to bill standard anaesthesia time units or basic units in addition to E032C, as E032C is a flat-fee replacement for those components.
Confusing procedural sedation with deep sedation; billing E032C for light or moderate sedation will result in audit recovery.

Billing Tips

Always append eligible GP97 extra units (e.g., E014C for BMI or E007C for age) to E032C to ensure you are not under-billing for high-risk patient factors.
Ensure your documentation clearly distinguishes the level of sedation as 'deep' or 'general' to justify the use of E032C over non-billable procedural sedation.
