Referring Physicians


Thank you for considering HNI for the neurology needs of your patients. Patients are our first priority at HNI; we know that you would not want it any other way. HNI knows that you too, are a client and deserve special care as well. We strive to make the interaction between your office and ours as efficient and productive as possible. Please consider using the tools below to assist you in your referral needs. If you have any questions, concerns, or suggestions in regards to these tools, the referral process, or our services, please do not hesitate to call us. Carol Hampton is our business manager in charge of process and policy. Tamela Jernigan, our billing manager, is responsible for insurance matters, including authorizations.

In addition to consultation, HNI physicians perform additional services.


These services are performed outside of the consultation appointment calendar, allowing for much more rapid scheduling and turnaround times for your testing needs.

EMG/NCV studies are performed Tuesday, Wednesday, Thursday, and Friday at one of the two HNI offices. Turnaround time for reports is usually same day or next day.

EEG including sleep deprived, prolonged, ambulatory and video EEG services are performed daily at the Pasadena location. Turnaround time depends on the length of the study but is usually between one day and one week.

Polysomnography including CPAP/BiPAP titration, following multiple sleep latency tests, and actigraphy are done nightly except Sundays. Results are reported within one week. The sleep coordinator can facilitate all sleep patient aftercare including interactions with DME providers as needed. 

Intraoperative electrophysiologic monitoring is arranged with the hospitals and surgeons requiring the services.
