S100 – Total thoracic oesophageal myotomy
OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Total thoracic oesophageal myotomy is a surgical repair procedure on the oesophagus. This fee code applies when it is the sole procedure performed. As a surgical procedure, the fee includes pre-operative evaluation, the operation itself, and normal post-operative care.
When to Use
- Use S100 for a total thoracic oesophageal myotomy performed as a standalone surgical procedure for conditions such as achalasia.
- Use S100 in conjunction with E758 when a concurrent oesophageal hiatus hernia repair is performed during the same operative session.
Common Pitfalls
- Failure to append the E683 modifier when performing the procedure via VATS or robotic-assisted approach, resulting in a 35% underpayment.
- Attempting to bill for a surgical assistant without prior authorization; payment for S100B requires a formal letter of justification submitted via M400B.
- Assuming standard anaesthesia units apply; S100C requires independent consideration as no fixed basic units are assigned.
Billing Tips
- Always verify the patient's age at the time of service to ensure the appropriate age-based percentage premium (ranging from 10% to 30%) is applied to the base fee.
- Ensure the E683 modifier is clearly linked to the S100 claim to capture the 35% increase for minimally invasive or robotic approaches.
