Do I need to see a primary care physician before I see an oncologist?

This varies, based on your health plan requirements. However, if your plan is an HMO, then yes, you will be required to see your primary care physician (PCP) and obtain a referral to see an oncologist. Most Point of Service (POS) plans also require that you see your PCP before you can get a referral to an oncologist. In general, most PPO or Indemnity plans, you do not need to see your family physician or PCP first. The best resource is your member summary of benefits booklet.
