This document addresses the use of intravenous (IV) vs. oral (PO) versions of exactly the same drug. The use of different drugs within the same therapeutic class is not addressed in this document.
Certain IV drugs have documented clinical efficacy that is bio-equivalent to the PO route of administration. When this is the case, and a stable individual requires long-term drug therapy, then PO administration of the drug is generally preferred. The purpose of this document is to help ensure that the most effective and least invasive form of drug administration is used when the IV and PO routes are bio-equivalent and used in the outpatient or home setting.
The use of the oral route of drug administration is considered medically necessary if both of the following are met:
- There is clear, well-documented evidence that the IV and oral preparations of the drug are bio-equivalent*; and
- Individual can tolerate enteral intake, including via oral, nasogastric or percutaneous endoscopic gastrostomy (PEG) tube routes.
The use of the IV route of administration is considered medically necessary if both of the following are met:
- The efficacy of the IV form is required; and
- The individual cannot tolerate enteral medication administration. Examples include, but are not limited to:
- Gastrointestinal (GI) malabsorption
- Bowel obstruction
*Examples of bio-equivalent IV and oral medications include, but are not limited to:
Proton Pump Inhibitors
Not Medically Necessary:
The IV route of administration for medications that have oral preparations which are bio-equivalent and the individual can tolerate oral intake is considered not medically necessary.
The following codes for treatments and procedures applicable to this document are included below for informational purposes. Inclusion or exclusion of a procedure, diagnosis or device code(s) does not constitute or imply member coverage or provider reimbursement policy. Please refer to the member's contract benefits in effect at the time of service to determine coverage or non-coverage of these services as it applies to an individual member.

If the oral and IV routes of select medications are bio-equivalent (per Food and Drug Administration [FDA]-approved package insert), there would be no apparent clinical benefit to using the IV over the PO route unless the GI tract is somehow compromised.
A Cochrane review (Kilburn, 2010) reported on the safety and efficacy of interventions for cellulitis. It was determined that no two trials reported on the same drug. Many trials compared the addition of corticosteroid to antibiotic treatment versus antibiotic treatment alone. The authors concluded "There is a need for trials to evaluate the efficacy of oral antibiotics against intravenous antibiotics in the community setting as there are service implications for cost and comfort."
