Procedural sedation billing in Alberta

Procedural sedation is one of the most commonly under-billed services in Alberta emergency departments.

When an ER physician administers sedation for a procedure — fracture reduction, abscess drainage, cardioversion, joint reduction — the sedation itself is a separately billable service. But in the fast pace of an ER shift, it's often absorbed into the encounter without being billed.

Why procedural sedation billing gets missed

The primary procedure gets billed. The ER visit code gets billed. But the sedation — which involves drug administration, continuous monitoring, and recovery observation — is frequently not billed as a separate service. Reasons include:

• Uncertainty about whether sedation is separately billable alongside the primary procedure
• Not knowing which code to use for the specific sedation scenario
• Forgetting to document the sedation time (start to recovery) separately
• Assuming sedation is bundled into the procedure code (it often isn't)

When sedation is separately billable

Procedural sedation is generally separately billable when:

• The sedation is administered by the physician performing the procedure (not by a separate anaesthesiologist)
• The sedation involves continuous monitoring and dedicated physician attention during the recovery period
• The chart documents the sedation drugs, doses, monitoring, and timing
• The specific code rules allow separate billing (check code-specific exclusions)

Documentation requirements

To bill procedural sedation defensibly, the chart must document:

• Pre-sedation assessment — patient airway, fasting status, ASA classification
• Drugs and doses — medication names, doses, route, timing of administration
• Monitoring — vital signs, oxygen saturation, level of consciousness during the procedure
• Time — sedation start time, procedure start/end, recovery start/end
• Recovery — discharge criteria met, patient status at discharge from monitoring

Common billing errors

1. Not billing sedation at all

The most common error. The physician performs sedation, bills the procedure, and doesn't add the sedation code. Over a year of ER shifts, this represents significant uncaptured revenue.

2. Not documenting time

Time-based sedation codes require documented start and end times. Without this documentation, the code isn't defensible even if the sedation was performed.

3. Billing sedation when an anaesthesiologist was present

If a separate anaesthesiologist provided the sedation, the ER physician typically cannot bill for it. The billing goes to the anaesthesiologist.
