Geriatric Medicine Billing, Credentialing

Geriatric medicine billing pays for far more than office visits, because Medicare has separate codes for the wellness planning, care coordination, and dementia care that fill most of a geriatrician’s week. The catch is that each of those codes comes with its own consent rule, frequency limit, or same-month conflict, and a practice that misses one either loses the payment or has to refund it. With more than half of eligible beneficiaries now in Medicare Advantage, the credentialing side matters just as much, since a geriatrician outside a patient’s MA network often can’t see that patient at all.

Key Takeaways

Traditional Medicare, Medicare Advantage, and Dual Eligibles

A typical geriatric panel splits three ways. Traditional Medicare patients follow national coverage rules and the Part B fee schedule. Medicare Advantage patients, who make up about 55% of eligible beneficiaries in 2026, follow whatever prior authorization, referral, and network rules their plan sets. Dual eligible patients add Medicaid as a secondary payer, which changes who owes the cost-sharing.

The same service can land differently in each group. A home visit that pays cleanly under traditional Medicare may need an authorization under one MA plan and fall out of network under another. Checking which program a patient is in before the visit, not after the denial, is the first step in optimizing reimbursement for an older panel.

Qualified Medicare Beneficiaries need a flag of their own in the practice management system. Federal law bars billing a QMB patient for Medicare deductibles, coinsurance, or copays, so a statement for the 20% on a care management claim is a compliance problem rather than a collections one. The practice can bill the state Medicaid program for those amounts, which may pay some, all, or none of them depending on the state.

Welcome Visits and Annual Wellness Visits

The Initial Preventive Physical Exam (G0402) is available once, within the first 12 months of a patient’s Part B coverage. After that first year, the annual wellness visit takes over, billed as G0438 for the first AWV and G0439 for each one after it. Neither the IPPE nor the AWV has a deductible or coinsurance when billed as a preventive service.

Timing is where most AWV denials come from. Medicare pays the next AWV only after at least 11 full months have passed following the month of the previous AWV or IPPE, so a visit booked a few weeks early comes back unpaid. Front desk staff should check the last wellness date in the eligibility response before scheduling.

The AWV is a planning visit, not a head-to-toe physical. It covers a health risk assessment, a medication and functional review, a cognitive screen, and a written prevention plan. When the provider also manages a problem during the same encounter, that work bills as a separate E/M service with modifier 25, and the patient’s normal cost-sharing applies to that portion.

Advance care planning fits naturally into the AWV. When 99497 (and 99498 for each additional 30 minutes) is billed on the same day as the AWV with modifier 33, the patient owes no deductible or coinsurance for the ACP time. Outside the AWV, the same codes carry standard Part B cost-sharing.

Monthly Care Management

Much of what a geriatric practice does between visits, such as medication follow-up, specialist coordination, and caregiver calls, can be billed under a monthly care management code. The right code depends on how many chronic conditions the patient has and who does the work.

APCM bundles CCM, PCM, and several virtual services, so the same clinician can’t bill CCM, PCM, or TCM for a patient in a month when APCM is billed. When a patient qualifies for both APCM and TCM in a given month, the practice chooses which one to report. Practices that run behavioral health integration alongside APCM can add G0568, G0569, or G0570 in the same month.

Every one of these programs needs documented patient consent before the first claim, and Part B coinsurance applies each month for patients without secondary coverage. Patients who weren’t told about that monthly charge are the most common source of complaints and write-offs in care management programs. Practices that also track blood pressure, weight, or glucose at home bill that work separately under the codes on our remote patient monitoring page.

Dementia and Cognitive Care Planning

CPT 99483 pays for a full cognitive assessment and care plan for a patient with suspected or diagnosed cognitive impairment. It often follows an AWV cognitive screen that turned up a concern, and it can be billed as its own visit rather than folded into the wellness visit.

The code has a long list of required elements. The visit needs a standardized cognitive test, an assessment of daily functioning and decision-making capacity, medication reconciliation, a review of behavioral and depressive symptoms, a home and driving safety evaluation, identification of the caregiver, advance care planning, and a written care plan shared with the patient or caregiver. Leaving out any one of them is enough for the claim to fail on review.

Medicare pays 99483 once every 180 days per patient, and the service can be furnished by telehealth. Practices that see a high volume of dementia patients should track the 180-day window per patient, because a second claim inside it denies even when the documentation is complete.

Visit Add-On Codes

G2211 is a Medicare add-on for the extra complexity of being a patient’s continuing source of care, and most geriatric follow-up visits fit that description. It started with office visits in 2024, and for 2026 Medicare extended it to home and residence visits (99341 to 99350). Our post on the G2211 add-on code covers when it applies and when it doesn’t.

Long office visits are common with older patients who bring several conditions and a caregiver. When total time runs well past the threshold for a level 5 visit, Medicare pays prolonged time under G2212 rather than the CPT code 99417 that many commercial plans use.

G0136 changed meaning for 2026. CMS dropped the social determinants of health risk assessment and revised the code to cover a standardized assessment of physical activity and nutrition, billed with an E/M visit no more than once every six months. Templates that still pair G0136 with an SDOH screening tool need to be updated.

Home, Assisted Living, and Nursing Facility Visits

Geriatricians who see homebound patients or residents of assisted living bill the home and residence visit codes (99341 to 99350), with a place of service that matches where the patient actually lives. Nursing facility visits use their own code family, and for 2026 Medicare permanently removed the frequency limit on subsequent nursing facility visits furnished by telehealth. Our guide to nursing facility CPT codes breaks down that family.

Practices that round in facilities often work alongside two other billing systems. The facility bills its own Part A stay, covered on our skilled nursing facility page, and agencies providing skilled care at home bill under the system on our home health page. The physician side bills separately under Part B in both cases.

Geriatric Medicine Code Reference

Geriatric Medicine Credentialing

Training and board certification

Geriatricians finish residency in internal medicine or family medicine and then complete a one-year geriatric medicine fellowship. Board certification in geriatric medicine comes through the American Board of Internal Medicine or the American Board of Family Medicine, depending on the primary specialty. Payers verify both certifications, plus the state license, DEA registration, malpractice history, and any hospital or facility privileges.

NPs, PAs, and every setting they cover

Many geriatric practices send nurse practitioners and physician assistants on nursing facility rounds and home visits. Each one needs an individual Medicare enrollment through PECOS, a reassignment of benefits to the group, and separate credentialing with every Medicare Advantage and Medicaid plan their patients carry. Claims for that provider can’t go out until each enrollment is approved, which is the core of why you can’t bill what you can’t credential.

Medicare Advantage networks

For a geriatric practice, the list of MA plans it participates in largely decides which patients it can see in network. Each plan credentials on its own timeline and recredentials on its own cycle, usually every three years, so a group with a dozen MA contracts has recredentialing dates coming due throughout the year.

MIPS and Quality Reporting

Geriatricians who bill Medicare Part B report through the Merit-based Incentive Payment System unless they participate in a qualifying alternative payment model. Falls risk screening, advance care plan documentation, and medication review are among the measures geriatric practices report most often. Because a MIPS score adjusts Part B payment two years after the performance year, the 2026 reporting shapes what the practice is paid in 2028. Our guide to MIPS performance covers scoring in each category.

Geriatric Medicine Billing FAQ

Medwave’s Geriatric Billing and Credentialing Team

Geriatric revenue tends to leak in small amounts. An AWV gets booked a month early, a CCM month overlaps APCM, or a QMB patient gets a statement that never should have gone out. Medwave builds those checks into the claim workflow, so each service goes out when it qualifies and not before. Our medical billing team holds a 98% clean claim rate, and wellness, care management, and facility claims all go through that same review.

On the enrollment side, our medical credentialing team gets geriatricians, NPs, and PAs approved in an average of 85 days, including each facility and home setting they cover. Our payer contracting work focuses on the Medicare Advantage plans that decide how much of a senior panel stays in network. Groups that also see younger adults can find related services on our primary care page.
