The Geriatric Medicine Billing Cycle
Geriatric medicine billing is unique because it combines standard E/M encounter billing with multiple non-encounter revenue streams (CCM, TCM, RPM, advance care planning) that generate monthly recurring revenue. A geriatric practice with 1,500 active patients may generate 30% to 40% of total revenue from non-encounter codes. The billing workflow must track encounter-based claims (AWVs, office visits, cognitive assessments), monthly recurring claims (CCM, RPM), and event-triggered claims (TCM after hospital discharge). Each stream has different documentation requirements, different billing cycles, and different payer rules.
Step 1: Medicare Eligibility and AWV Scheduling
Verify Medicare eligibility and AWV status at every patient contact. The initial AWV (G0438) is available one year after the effective date of Medicare Part B enrollment. Subsequent AWVs (G0439) are available every 12 months after the initial AWV. Check the patient Medicare claims history to verify when the last AWV was performed, because billing an AWV within 11 months of the previous one triggers a denial. Proactively schedule AWVs for eligible patients by running a monthly report of patients due for their annual visit. A dedicated AWV scheduling workflow can increase AWV completion rates from 30% to 70% of the Medicare panel.
Step 2: Encounter Documentation for Geriatric Codes
Geriatric-specific codes require more structured documentation than standard E/M visits. For the AWV, use a templated health risk assessment (HRA) that captures functional status, fall risk, home safety, depression screening (PHQ-2 or PHQ-9), cognitive screening, medication list, and preventive service schedule. For code 99483 (cognitive assessment), the documentation template must include all required elements: standardized cognitive test scores, functional assessment, medication review for cognitive-impairing drugs, neuropsychiatric symptom evaluation, safety assessment, caregiver needs, and the written care plan. Using structured EHR templates for these codes reduces documentation time by 40% and ensures no required elements are missed.
Step 3: CCM Enrollment and Monthly Billing
CCM requires patient consent before billing can begin. The consent process must inform the patient that: only one provider can bill CCM per month, there may be cost-sharing (approximately $8 to $12 per month for 99490), the patient can revoke consent at any time, and the practice will provide non-face-to-face care coordination services. Once consent is obtained, the care coordinator logs non-face-to-face CCM activities monthly: medication management phone calls, coordination with specialists, lab result review and follow-up, home health coordination, and caregiver communication. Bill CCM on the last day of the calendar month (or the first business day of the following month) after confirming that the minimum time threshold (20 minutes for 99490) has been documented.
Step 4: TCM Tracking After Hospital Discharge
TCM billing requires three time-sensitive actions after a patient is discharged from a hospital, skilled nursing facility, or other inpatient facility. First, make interactive contact (phone call, not voicemail) within 2 business days of discharge. Second, schedule and complete a face-to-face visit within 7 days (99496, high complexity) or 14 days (99495, moderate complexity) of discharge. Third, perform medication reconciliation and coordinate with the discharging facility. Track hospital admissions in real-time by monitoring admission notifications (ADT feeds), checking with local hospitals, or having patients and families call the practice upon discharge. Missed TCM opportunities represent $170 to $260 per event in lost revenue.
Step 5: Claim Submission and Medicare-Specific Rules
Submit Medicare claims electronically through the MAC (Medicare Administrative Contractor) serving your region. Geriatric-specific billing rules to follow: the AWV is billed with HCPCS codes (G0438/G0439), not CPT preventive visit codes (99381-99397) which are not covered by Medicare. Advance care planning (99497/99498) requires the ACP modifier (not modifier 25) when billed with the AWV. CCM requires that the billing provider have a face-to-face relationship with the patient within the past 12 months. TCM can only be billed once per patient per 30-day transition period, and only by the provider managing the transition. Submit each claim type within its specific window: encounter claims within 48 hours, CCM claims by the 5th of the following month, and TCM claims within 30 days of the discharge date.
Step 6: Quality Reporting and Value-Based Payment
Geriatric practices participating in MIPS (Merit-based Incentive Payment System) or ACO (Accountable Care Organization) arrangements must track quality measures that affect future Medicare reimbursement. Common geriatric quality measures include: fall risk screening and plan of care (MIPS 318), dementia care plan documentation (MIPS 281), advance care plan documentation (MIPS 47), and depression screening (MIPS 134). Accurate billing of geriatric-specific codes (AWV, 99483, 99497) generates the data needed for quality reporting. Ensure that the billing system captures quality measure data elements from the encounter documentation and reports them through the appropriate quality reporting channel.
