Not really sure what you're saying "no" to.
Roxicet is a combo drug, marketed as Roxicet, Percocet & Tylox.

Oxycodone is available without a supplemental drug, but then it's not known as Roxicet but as OxyIR, Roxicodone, Percolone or just as oxycodone.

What it's called just depends on if an analgesic is attached to it.

This medication is a combination of a narcotic (oxycodone) and a non-narcotic (acetaminophen) used to relieve moderate to severe pain. Oxycodone works by binding to opioid receptors in the brain and spinal cord, and acetaminophen decreases the formation of prostaglandins, therefore relieving pain.
