A 24-hour cancellation notice is required for a new patient appointment or you will be billed a charge for the missed visit.

Urgent Work-ins

If an urgent matter arises, Dr. Houston will do his best to see you that same day or refer you to the closest E.R. if considered an emergency. The E.R. physician will contact Dr. Houston regarding your medical condition.

What to Expect At Your Appointment

When you are called back to the examination room, you will be weighed, your vital signs will be taken, and the nurse will ask you a series of questions about your medications, medical history, etc. Bring all prescription medications; including vitamins and supplements, you are taking in their original container. After the nurse has finished, Dr. Houston will shortly enter the room and begin his examination.

When Dr. Houston has completed his exam with you, he will order tests depending on your medical history and age. For all new patients and annual physicals, Dr. Houston is very thorough and usually orders a series of tests.

For Women

Depending on age, a mammogram, breast thermography, and bone density tests may be ordered. Dr. Houston does not perform pelvic examinations, or Pap smears and requests that you establish a medical relationship with a gynecologist for those procedures.

Obtaining Lab and Test Results

If you would like a copy of your test results, please bring a self-addressed, stamped envelope with you on your visit. The lab results will be mailed to you in the envelope you provided. If you have any abnormal tests, Dr. Houston’s nurse will contact you or mail you the information. We DO NOT report normal labs by phone. Please DO NOT call to request normal labs. If you receive information in the mail and have any questions, please call the office and speak to one of Dr. Houston’s nurses. All tests will be reviewed with you on your follow-up visit.

Family Consent

If you would like for Dr. Houston’s staff to give medical information about you to a family member, you will need to give us written consent to speak with that person. Please list all names with whom we are allowed to speak. When checking in for your appointment, ask to complete a medical release form and you will be provided one.

If you reach our voicemail, leave a DETAILED message, including your name, date of birth, phone number, and a pharmacy number if needing a prescription refill. Emergency calls will be taken care of immediately. Non-emergency calls will be returned by the end of the day. If you are calling for a prescription refill, leave a message including the name of the medication needed. Check with your pharmacy at the end of the day to see if your prescription has been filled. We will call you only if we are unable to process your medication request. Please do not call and leave the same message multiple times.
