S790 – Thyroidectomy - hemi
OHIP Urology Code — ENDOCRINE SURGICAL PROCEDURES · Schedule of Benefits
Hemi-thyroidectomy is the surgical removal of one half of the thyroid gland. This procedure is listed in the Schedule of Benefits under the 'Thyroidectomy' subheading within 'Endocrine Surgical Procedures'.
When to Use
- Use S790 for the unilateral resection of a thyroid lobe, typically performed for benign nodules, indeterminate cytology, or localized malignancy.
- Use this code when the procedure is limited to one side; if a total thyroidectomy is performed, S792 is the appropriate code instead.
Common Pitfalls
- Billing S790 in conjunction with S792 for the same patient on the same day is a common error; the Schedule of Benefits considers these mutually exclusive based on the extent of the resection.
- Attempting to bill for a second surgical assistant without prior authorization will result in automatic rejection, as S790 is not on the pre-approved list for multiple assistants.
Billing Tips
- If a second assistant is medically necessary due to complex anatomy or high-risk pathology, ensure the surgeon submits a formal letter of justification to the Ministry to secure the required authorization for the second assistant's fee.
