Get a Prescription for Medications

IHN-CCO will pay for most drugs if you have a prescription from your primary care provider, primary care dentist or mental health provider. You may fill prescriptions at almost any pharmacy in Benton, Lincoln and Linn counties. Just ask your pharmacy if they accept IHN-CCO.

Covered Medications

IHN-CCO uses a “formulary” for prescription drugs. A formulary is a list of covered prescription drugs. All IHN-CCO providers have a copy of the formulary in their office. When you need a prescription, your doctor will choose a drug from the formulary. Drugs that are not on the formulary are called non-formulary. If you would like a copy of our formulary, call our Customer Service Department and we will send you one within five business days.

IHN-CCO covers many over the counter (OTC) drugs which will be listed on our formulary. If an OTC drug on formulary is listed with a limit on the number you can get, or prior approval is needed, you may need to get approval. If an OTC drug is not listed on the formulary, a prior approval will be needed before IHN-CCO will pay for the drug.

As an IHN-CCO member you can get birth control from any provider. You do not need a referral or prior approval.

If there are problems with the pharmacy filling your prescription, your provider can call our Customer Service Department.

If for some reason you need a drug that is not on the IHN-CCO formulary, your doctor can ask for an exception. Our Pharmacy Director will decide if it is medically needed for you to have a drug that is non- formulary. If you have a high medical need for the prescription, we will pay for the non-formulary drug.

Be sure to talk to your PCP, PCD or mental health provider who can provide the drug before you go out of town. They can help you get medication refills before you leave or tell you what to do if you run out of medication.

Tips for Filling Prescriptions

  • Be sure to bring your ID card to the pharmacy to get your prescription filled.
  • Some types of drugs require your doctor to contact us before you can receive your prescription. This is called a prior authorization. Your doctor will let you know when the prescription has been authorized.
  • Some types of drugs have quantity limits. This means there is a set limit to the amount of these drugs that you can receive. Your doctor will work with us to ensure you receive the right amount for your needs.
  • Be sure to talk to your doctor, dentist or mental health provider who provides the medications before you go out of town. They can help you get medication refills before you leave or tell you what to do if you run out of medication.

Here are a few forms you or your provider may need. These forms relate to your prescription coverage:
