A presumption of coverage for routine foot care exists when the physician rendering the service documents and bills using modifier Q7 (one Class A finding), Q8 (two Class B findings), or Q9 (one Class B plus two Class C findings) and a systemic condition diagnosis from the listed conditions is present.
Non-invasive vascular diagnostic tests are covered when ordered by the treating practitioner or a consulting physician who will use the results to manage the beneficiary's specific medical problem.
A documented referral/order must be on record for each individual non-invasive vascular study performed for coverage to apply.
