Office Policies

How do I schedule an appointment?
We have appointment staff at our location to assist you in making an appointment. When you call, our appointment staff will ask you a few questions regarding your medical needs. This is to help us schedule the appropriate amount of time with the doctor. Giving thorough information when making the appointment may help you avoid having to schedule another appointment at a later time to address additional needs. Please have your insurance information available when you are calling to schedule your appointment. It is best to arrive ten minutes early for your appointments in order to complete or update patient information. We ask new patients to arrive thirty minutes early to fill out required information. If you arrive fifteen minutes late for a regularly scheduled appointment or five minutes late for a procedure you may be asked to reschedule at the physician’s discretion. If you must cancel an appointment, please call us as soon as you become aware that you are unable to keep it. We ask that you notify us at least 24 hours in advance. We would like to help you re-schedule, and your previous slot can then be given to another patient. (If you miss three or more appointments within one year without 24 hours prior notice,you may be dismissed as a patient from Cascade Family Practice.)
Do you accept walk-ins?
We realize that at times our patients have urgent needs that will not allow them to wait several days for an appointment. When these needs arise, please call our appointment line at 503-233-5273, and we will make every effort to get you in the same day.
What should I bring to my appointment?
All patients should bring a list of any medications they are currently taking, as well as their insurance card and their driver’s license when coming in for an appointment.
Do I need to send my old records prior to my first visit?
For annual exams or treating chronic medical issues, it is recommended that your previous medical records be available for our physician or nurse practitioner’s review. Knowing your complete medical history allows us to more readily identify the source of your medical problem and develop the appropriate treatment plan for you.
How can I receive a copy of my medical records?
Records may be transferred to another physician’s office or hospital as a complimentary service. There is a 50¢ per page fee for records copied for insurance, legal, and individual purposes. We must have a signed release before releasing patient records (see PDF link below for a printable form). Please allow 48-72 hours processing time.
How do I get my lab and test results?
Most lab and test results are available within 24 hours except in the case of a CT scan, MRI, pathology report or culture. Once they are complete, they are added to our Electronic Medical Record and sent first to the Physician for review and follow-up. After the Physician reviews the report, it is available for the Medical Assistant, Nurse Practitioner or the Physician to communicate the results to you. If, after 48 hours, you have NOT yet heard or been given the results of your lab test, please contact us and we should be able to have the nurse provide that information for you.
How are Prescription refills handled?
We will give you, at the time of your visit, 3-6 months of refills of your medication (depending on how much monitoring your condition requires). We do not routinely fill prescriptions over the phone; However, if you run out of your medication and forget to make an appointment, we will make an appointment for you and provide enough medication to make it to that appointment.
How do I contact someone after hours or in an emergency?
An on-call physician or nurse practitioner is available 24 hours, 365 days a year. After our normal office hours, you may contact them through our answering service at 503-299-1266. If you have a life threatening emergency, go to the emergency room nearest to you. The hospital Emergency Room Physician will contact your Cascade Family Practice Physician or Nurse Practitioner and they will jointly decide how to best treat your condition.
Are you accepting new patients?
Yes, we welcome new patients. If you think you may wish to transfer your medical care to us, please stop in and get acquainted with us.

We also offer Osteopathic Manipulative Treatment for those with muscle and skeletal problems.
At Cascade Family Pracitce we do not refill medications over the phone. We will give you medication refills to last 3 to 6 months, at the time of your appointment, depending on your diagnosis. To provide the best medical care possible, we need to monitor your condition.

What is your financial policy?

We strive to keep our fees fair and competitive with our community. Cash or checks are accepted as payment for services.
We participate with many insurance plans. Co-pays, co-insurance, and deductibles are due at the time of service. If we are a participating provider with your insurance company, we will file your insurance claims and accept payments from your insurance company.
In order to provide this service, we will need to verify health insurance coverage with the following information:
name and address of insurance company
group number
subscriber’s and/or patient’s full name
subscriber’s and/or patient’s social security number
subscriber’s and/or patient’s
insurance identification number
subscriber’s and/or patient’s place of employment
subscriber’s and/or patient’s correct address
subscriber’s and/or patient’s date of birth
We ask that you present your current insurance card at each visit. In order to avoid billing problems, it is vital that you provide us with updated information as the changes occur. There may be times when the patient will be asked to file his/her own insurance claims or to follow up personally with the insurance company. If the insurance has not paid within 60 days, the outstanding balance will be considered patient responsibility and payment will be due at that time. New patients are required to pay the first visit in full at the time of service unless we are able to verify insurance eligibility and benefits before your appointment. A refund will be issued if the insurance pays for the visit. Non-insured patients will be asked to pay the balance in full as services are rendered or to make payment arrangements with the Business Office before receiving care. We do offer a prompt pay 25% discount for non-insured patients. At Cascade Family Practice, we endeavor to provide to our patients the best possible medical care. In return, we expect our patients to meet their financial obligations.

What are the advantages of a high-deductible insurance plan?

The annual cost for medical services is less than $2000 for more than 90% of the US population. So, high-deductible health insurance policies are often available that are very affordable. For example, a family might save nearly $5,000 per year in insurance premiums by purchasing a $2,000 deductible (per family member) insurance policy for $200/month. The same policy with a $250 deductible is often around $600/month. So, the combination of a high deductible plan plus an annual physical combined with health savings account and virtual office visits is often a good value. Rates and policies vary widely by one’s health, employer, location, and age. We offer discounted fees if payment is made at time of service.

Common Questions

If you’re like most people, you’ve been going to a doctor since you were born and perhaps didn’t know if you were seeing a D.O. (osteopathic physician) or an M.D. (allopathic physician). You may not even be aware that there are two types of complete physicians in the United States.
The fact is, both D.O.s and M.D.s are fully qualified physicians licensed to perform surgery and prescribe medication. Is there any difference between these two kinds of doctors? Yes. And no.
D.O.s bring something extra to medicine
Osteopathic medical schools emphasize training students to be primary care physicians.
D.O.s practice a “whole person” approach to medicine. Instead of just treating specific symptoms or illnesses, they regard your body as integrated whole.
Osteopathic physicians focus on preventive health care.
D.O.s receive extra training in the musculoskeletal system — your body’s interconnected system of nerves, muscles and bones that make up two-thirds of its body mass. This training provides osteopathic physicians with a better understanding of the ways that an injury or illness in one part of your body can affect another.
Osteopathic manipulative treatment (OMT) is incorporated in the training and practice of osteopathic physicians. With OMT, osteopathic physicians use their hands to diagnose injury and illness and encourage your body’s natural tendency toward good health. By combining all available medical procedures with OMT, D.O.s offer their patients the most comprehensive care available in medicine today.
More than a Century of Unique Care
Osteopathic medicine is a unique form of American medical care that was developed in 1874 by Dr. Andrew Taylor Still. Dr. Still was dissatisfied with the effectiveness of 19th Century medicine. He believed that many of the medications of his day were useless or even harmful. Dr. Still was one of the first in his time to study the attributes of good health so that he could better understand the process of disease.
In response, Dr. Still founded a philosophy of medicine based on ideas that date back to Hippocrates, the father of medicine. The philosophy focuses on the unity of all body parts. He identified the musculoskeletal system as a key element of health. He recognized the body’s ability to heal itself and stressed preventive medicine, eating properly and keeping fit.
Dr. Still pioneered the concept of “wellness” more than 125 years ago. In today’s terms, personal health risks–such as smoking, high blood pressure, excessive cholesterol levels, stress and other lifestyle factors–are evaluated for each individual. In coordination with appropriate medical treatment, the osteopathic physician acts as a teacher to help patients take more responsibility for their own well-being and change unhealthy patterns.
21st Century Frontier Medicine
Just as Dr. Still pioneered osteopathic medicine on the Missouri frontier in 1874, today osteopathic physicians serve as modern day medical pioneers. They continue the tradition of bringing health care to areas of greatest need:
Approximately 65% of all osteopathic physicians practice in primary care areas such as pediatrics, family practice, obstetrics/gynecology and internal medicine.
Many D.O.s fill a critical need for doctors by practicing in rural and medically underserved areas.
Today osteopathic physicians continue to be on the cutting edge of modern medicine. D.O.s combine today’s medical technology with their ears, to listen compassionately to their patients; their eyes, to see their patients as whole persons; and their hands, to diagnose and treat injury as well as illness.
D.O.s and M.D.s are alike in many ways:
Applicants to both D.O. and M.D. medical colleges typically have a four-year undergraduate degree with an emphasis on scientific courses.
Both D.O.s and M.D.s complete four years of basic medical education.
After medical school, both D.O.s and M.D.s can choose to practice in a specialty area of medicine — such as surgery, family practice or psychiatry–after completing a residency program (typically two to six years of additional training).
Both D.O.s and M.D.s must pass comparable state licensing exams.
D.O.s and M.D.s both practice in fully accredited and licensed health care facilities.
D.O.s comprise a separate, yet equal branch of American medical care. Together, D.O.s and M.D.s enhance the state of care available in America. It is, however, the ways that D.O.s and M.D.s are different that bring an extra dimension to your family’s health care.

(American Osteopathic Association Copyright 2003-2006)

A nurse practitioner (NP) is a registered nurse with advanced academic and clinical experience, which enables him or her to diagnose and manage most common and many chronic illnesses, either independently or as part of a health care team. A nurse practitioner provides some care previously offered only by physicians and in most states has the ability to prescribe medications. Working in collaboration with a physician, a nurse practitioner provides high-quality, cost-effective and individualized care for the lifespan of patient’s special needs.
NPs focus largely on health maintenance, disease prevention, counseling and patient education in a wide variety of settings. With a strong emphasis on primary care, nurse practitioners are employed within several specialties, including neonatology, nurse-midwifery, pediatrics, school health, family and adult health, women’s health, mental health, home care, geriatrics and acute care.
