Neurology Medical Billing Services: Authorizations and Time-Based Codes
MRI, EEG, and injection-based neurology procedures each carry their own authorization and documentation rules.
Jargon Buster is on: hover or tab to any underlined term for a plain-English definition.
Why neurology billing spans several different billing types
A neurology practice bills office visits, diagnostic studies (MRI, EEG), and procedures (chemodenervation injections) that each have separate authorization and documentation requirements. See neurology billing considerations.
Where neurology claims get denied
- MRI, EEG and chemodenervation injections frequently need authorization, and volume makes it easy to miss one
- Time-based EEG monitoring codes require documentation that matches the billed duration precisely
- Drug codes (for injections like Botox) must be billed with correct units and NDC numbers
- Authorization obtained for a shorter or different study than what was ultimately performed doesn't cover the claim as billed
Why EEG monitoring documentation matters so much
Several EEG codes bill by duration of monitoring, so the clinical record has to clearly support the exact time billed, not an estimate.
What to check before outsourcing neurology billing
| Area | Risk if missed | What to ask |
|---|---|---|
| Imaging/EEG/injection authorization | Denial for missing or mismatched auth | How do you track authorization across study types? |
| EEG time documentation | Duration mismatch → denial | How do you verify monitoring time against documentation? |
| Drug unit/NDC accuracy | Partial denial | How do you handle drug unit and NDC accuracy for injections? |
Questions to ask
- Ask how they track authorization status across MRI, EEG, and injection procedures separately
- Ask how they verify EEG monitoring time against documentation before submission
- Ask how they handle drug unit and NDC accuracy for injections
This depends on eligibility and prior authorization and careful coding and charge entry. A billing audit can show where authorization or documentation gaps are already costing revenue.
Frequently asked questions
Not all, but MRI, EEG and chemodenervation injections commonly do, and it should be checked per payer rather than assumed.
