I'm afraid I disagree wholeheartedly with the last comment. Depression screening(in the form of a PHQ-9 in our case) is always covered as a separate service when done with a preventive visit, whether the policy is Med B, Medicare Advantage, commercial or Medicaid. The worst case scenario is that, in some BCBS and ConnectiCare commercial policies, they may pass the approx. $8.68 on to the patient as a coinsurance, but they still consider it a covered service. Do not miss out on a very easy way to be reimbursed for work done.
Also, as an aside, I have found that very few payers pay for depression screening and smoking cessation on the same DOS.
