"The code gets denied because the note doesn't say the word 'functional' — one word. We fix that."
A Comprehensive Geriatric Assessment (CPT 99483) is the most thorough visit Medicare covers. It takes 50 minutes and covers your memory, medications, fall risk, and daily function. But insurers deny it constantly — not because the visit was wrong, but because the doctor's note missed a specific phrase. Our billing team reviews every note before it goes to the insurer. We catch the gaps that cause denials before the claim even leaves our office.
We review your doctor's note for required documentation elements
We confirm your plan covers code 99483 before the visit
If denied, we file an appeal with the corrected documentation within 5 business days

"'Incident-to' sounds complicated. It just means: did your doctor supervise the visit? If yes, Medicare pays the same rate."
When a nurse practitioner or physician assistant sees you, Medicare has a rule called "incident-to" billing. If your doctor is in the building and supervises the visit, Medicare pays the full 100% physician rate. If not, Medicare pays only 85% — and your share goes up. At Copay, we schedule visits to always meet the supervision requirement. You should never pay more because of a staffing technicality.
Your visit is always scheduled when your supervising physician is on-site
Our front desk confirms the supervision requirement is met before your appointment
If your EOB shows an 85% payment rate, call us — it may be a billing error

"A denied claim is not a final answer. Seventy percent of appeals we file are reversed. You just have to know how to ask."
A denial letter can feel like a door slamming shut. It isn't. Medicare Advantage plans are required by law to review every appeal. Our team files the appeal, writes the letter, gathers the clinical notes, and tracks the deadline. You don't have to make a single phone call. In 2025, we reversed 71% of denied prior authorization requests for our patients. The most common reason for denial: the insurer said the service wasn't "medically necessary." The most common reason we win: we show them it was.
