G878
G878 – EMG and/or ultrasound guidance for two or more injections
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use G878 when performing multiple botulinum toxin injections (G870, G873, G874, or G876) where EMG guidance is clinically necessary to localize specific muscles for treatment.
- Select G878 instead of G877 when the procedure involves two or more injection sites requiring guidance.
Common Pitfalls
- Billing G878 in conjunction with G877 is a common error; these codes are mutually exclusive based on the number of injection sites.
- Failure to document the specific muscles targeted by EMG guidance will lead to audit recovery, as the code requires justification for the guidance itself.
- Attempting to bill G878 without an associated primary injection code (G870, G873, G874, or G876) will result in an automatic rejection.
Billing Tips
- If performing the procedure in a private office setting, remember to add E543 to your claim to recover the cost of the disposable EMG hypodermic electrode.
