If you have Medicare and see a primary care doctor regularly, there's a good chance you're leaving valuable covered services on the table — not because you declined them, but because your doctor never offered them. Primary care physicians in the United States are under enormous time pressure, often seeing 20 or more patients per day. In that environment, certain Medicare billing codes — and the services attached to them — get skipped, not because they aren't valuable, but because they require extra documentation, coordination, or patient education time that a 15-minute appointment doesn't easily accommodate. Understanding what these services are, and asking for them by name, can meaningfully change the quality of care you receive.
The first and perhaps most impactful underused service is Chronic Care Management, known in Medicare billing as CCM. If you have two or more chronic conditions — think diabetes and high blood pressure, or heart disease and arthritis — Medicare Part B covers at least 20 minutes per month of care coordination provided by your doctor's clinical staff. This isn't a visit; it's phone calls, medication reviews, coordination between specialists, and help navigating referrals. The monthly fee is billed to Medicare, and your cost-sharing is typically 20% of the Medicare-approved amount after your Part B deductible, though many Medicare Advantage plans cover it differently. The staggering reality is that despite millions of Medicare beneficiaries qualifying, enrollment remains extremely low. Ask your primary care office specifically: "Do you offer Chronic Care Management billing for Medicare patients?"
Advance Care Planning is another service that Medicare covers but that rarely comes up unless a patient initiates the conversation. Under billing code 99497, Medicare pays for a face-to-face conversation between you and your doctor (or a qualified non-physician practitioner) about your wishes for end-of-life care, including completing or reviewing advance directives like a living will or healthcare proxy designation. The first 30 minutes of this conversation are covered by Medicare Part B, and additional time can be billed separately. During your Annual Wellness Visit — itself a commonly skipped Medicare benefit — advance care planning can be provided at no cost to you. This is not a morbid conversation; it's a practical one that ensures your medical wishes are documented and followed if you're ever unable to speak for yourself.
The Annual Wellness Visit itself deserves its own spotlight because it is frequently confused with a regular physical exam, and that confusion costs beneficiaries money. Your Annual Wellness Visit (AWV) is a Medicare-specific benefit covered at no cost to you — no copay, no deductible — that focuses on preventive care, health risk assessment, and creating a personalized prevention plan. It is not the same as a comprehensive physical examination, which Medicare Part B does not cover in the traditional sense. During your AWV, your doctor should review your medications, screen for cognitive impairment, assess your fall risk, update your family history, and refer you to appropriate screenings. If your doctor's office is billing your AWV as a regular office visit and charging you a copay, that may be a billing error worth questioning.
Cognitive assessment is a specific component that Medicare covers as a standalone service when there's a concern about memory or thinking changes. Under the billing code for cognitive impairment assessment, your doctor can conduct a structured evaluation of your memory, language, attention, and problem-solving — and Medicare covers it. This matters because early detection of conditions like mild cognitive impairment or early Alzheimer's disease can open doors to treatment, care planning, and support services. Many physicians skip this assessment because it takes time and requires specific documentation, but you can request it directly. Simply tell your doctor: "I'd like a cognitive assessment done today — I understand Medicare covers it."
Behavioral health integration is a newer category of Medicare-covered services that most beneficiaries have never heard of. If you struggle with depression, anxiety, or other behavioral health conditions alongside physical health issues, your primary care practice can bill Medicare for coordinated behavioral health services provided within the primary care setting. This includes regular check-ins from a care manager, collaboration with a psychiatric consultant, and structured follow-up. These services are designed to bring mental health support into your regular doctor's office rather than requiring a separate referral to a psychiatrist — a significant barrier for many older adults. Medicare Part B covers these services, and they can be particularly valuable for beneficiaries in rural areas where mental health specialists are scarce.
Transitional Care Management is a service that kicks in when you're discharged from a hospital, skilled nursing facility, or other inpatient setting. Medicare covers two levels of this service — one for moderate-complexity cases and one for high-complexity cases — and the billing requires your doctor's office to make contact with you within two business days of discharge and then see you in person within 7 or 14 days depending on complexity. The problem is that many primary care offices don't have systems in place to track hospital discharges and initiate this outreach. If you've recently been hospitalized and your doctor's office hasn't called you within 48 hours, you can call them and specifically request a Transitional Care Management follow-up appointment. This service is associated with significantly lower rates of hospital readmission.
Medication Therapy Management, or MTM, is technically administered through Medicare Part D prescription drug plans rather than Part B, but it's worth including here because it's dramatically underutilized. If you take multiple medications for multiple chronic conditions and your drug costs exceed a certain threshold, your Part D plan is required to offer you a comprehensive medication review — a one-on-one consultation with a pharmacist who reviews all your medications for interactions, duplications, and opportunities to simplify your regimen. According to CMS.gov data, Medicare Part D plans enrolled approximately 13 million beneficiaries in MTM programs in recent years, yet many eligible beneficiaries never complete the comprehensive medication review they're offered. Check your Part D plan's website or call the member services number on your card to ask whether you qualify and how to schedule your review.
Screenings for depression, alcohol misuse, and obesity are three separate Medicare-covered preventive services that primary care physicians can provide during a regular office visit but frequently don't document or bill for. Medicare Part B covers annual depression screening using a validated tool like the PHQ-9 at no cost to you. Alcohol misuse screening and brief counseling — up to 15 minutes — is also covered at no cost. Intensive behavioral therapy for obesity, which includes up to 22 visits in the first year for beneficiaries with a BMI of 30 or higher, is covered as well. These aren't exotic services; they're straightforward screenings that take minutes to administer. If your doctor hasn't asked you about your mood, your drinking habits, or your weight management goals in the past year, it's reasonable to bring these topics up yourself.
Data Snapshot: According to CMS.gov data, there were 3,959 Medicare Advantage plans available to beneficiaries nationwide in 2024, and the average Medicare Part B premium in 2025 is $185.00 per month. Importantly, CMS data also shows that Chronic Care Management services — despite being available since 2015 — are billed for fewer than 5% of eligible Medicare fee-for-service beneficiaries, representing one of the largest gaps between covered benefits and actual utilization in the entire Medicare program. This gap exists not because beneficiaries don't need the service, but because the infrastructure to deliver and bill for it consistently is still developing in many primary care practices.
Remote Physiologic Monitoring is a rapidly growing category of Medicare-covered services that allows your doctor to track your blood pressure, blood glucose, weight, or other health metrics using connected devices at home. Medicare Part B covers the setup, device supply, and monthly data review for this service. If you have hypertension, diabetes, or heart failure, ask your doctor whether remote monitoring might be appropriate for you. Some practices have invested in the technology and staff to support this; others haven't. Knowing that Medicare covers it gives you the standing to ask the question.
Finally, the Welcome to Medicare Preventive Visit — formally called the Initial Preventive Physical Examination — is a one-time benefit available to you within the first 12 months of your Part B enrollment. It's covered at no cost and includes a review of your medical and social history, a health education and counseling session, and referrals to other covered preventive services. Many new Medicare beneficiaries don't know this visit exists, or they assume it's the same as their Annual Wellness Visit (it isn't — the AWV becomes available after your first year). If you enrolled in Medicare Part B within the last year and haven't had this visit, call your doctor's office and ask to schedule your Welcome to Medicare visit before your 12-month window closes.
The practical takeaway from all of this is straightforward: Medicare covers far more than most beneficiaries realize, and the gap between what's covered and what's actually delivered often comes down to whether the patient knows to ask. Print out a list of these services before your next appointment. Tell your doctor you'd like to discuss which ones apply to you. Primary care physicians respond to informed patients, and your Medicare benefits exist to be used — not left on the table because no one mentioned them.
