45378Endoscopy

Diagnostic colonoscopy

Prior authorization
Not commonly required

What this is, in plain language

A camera exam of the entire large intestine done with sedation, used to look for the cause of symptoms or to follow up on prior findings.

Why a clinician orders it

Bleeding, change in bowel habits, abdominal pain, anemia, follow-up of polyps, or surveillance after prior cancer.

Medical necessity — what insurers usually look at

Screening colonoscopies (different CPT codes) are often covered as preventive care. Diagnostic colonoscopies — done because of symptoms — usually do not need prior auth but may apply to your deductible.

Documentation to ask about

  • Symptoms or reason for the exam
  • Prior colonoscopy results, if any
  • Family history of colon cancer or polyps

Questions for your provider

  • ?Is this being billed as screening or diagnostic? How does that affect what I pay?
  • ?Is the facility and the anesthesia provider in my network?
