Geriatric Medicine BillingComplete Coding & Revenue Guide (2026)Top CPT codes with current RVU data, denial patterns, modifier rules, bundling pitfalls, and revenue opportunities for geriatric medicine practices.
Top CPT Codes
The highest-value geriatric medicine CPT codes with current RVU data and Medicare payment from the CY 2026 Physician Fee Schedule. Click any code for the full payment, bundling, and modifier guide.
Most practices under-capture revenue on these codes through downcoding, missed modifier 25, stale fee schedules, or misapplied bundling. Our coders audit every line against the documentation before submission so the revenue earned actually gets billed.
Bundling Pitfalls
1 trapsThe code pairs that trigger NCCI edits and CO-97 denials in geriatric medicine. Know these before billing.
G0438: G0439: Initial AWV (G0438) vs subsequent AWV (G0439): G0438 is the FIRST AWV ever (Welcome to Medicare within first 12 months). G0439 is subsequent (annual). Cannot bill both — ever. If patient had G0438 last year, all future AWVs are G0439.: 99483: G0439: Cognitive assessment (99483) can be billed WITH the AWV (G0439) on the same date. No modifier needed — they are complementary services. 99483 is a comprehensive cognitive assessment that goes beyond the brief screening included in the AWV.: 99341: 99350: Home visit codes: 99341-99345 (new patient home), 99347-99350 (established patient home). These are E/M codes with the same MDM complexity as office codes but set in the home. Cannot bill home visit + office visit same day for same patient.: 99490: 99491: CCM codes are mutually exclusive per month: 99490 (clinical staff, 20+ min) vs 99491 (physician, 30+ min). Cannot bill both. Choose based on who provided the majority of care coordination.: 99497: 99498: Advance care planning: 99497 (first 30 min) + 99498 (each additional 30 min). Can be billed with AWV on same date. Document the discussion content (code status, healthcare proxy, treatment preferences, POLST/MOLST).
CO-97 bundling denials are recoverable with correct modifier documentation. Most billers write them off. We work each one against the clinical record and resubmit with the right modifier 25 or 59 path.
Modifier Guidance
When to apply each modifier in geriatric medicine claims. Wrong modifier application is the top single-line denial trigger and a leading audit target.
Required on E/M when billing with same-day procedure (wound care, injection, vaccine). Document separately identifiable problem.
Telemedicine — geriatric follow-ups work well via telehealth. Cognitive assessments (99483) may require in-person for valid screening.
Principal physician of record — used in nursing facility billing to designate the managing physician.
Resident billing — common in academic geriatrics.
Legacy telehealth modifier — some Medicaid plans still require GT for geriatric telehealth. Most commercial and Medicare now accept POS 02/10 without GT.
Revenue Opportunities
7 playsThe billing codes and services most geriatric medicine practices under-capture. Each one is a recurring revenue lift, not a one-time fix.
Annual Wellness Visit: G0439 pays $175-250. With 200 Medicare patients, annual AWV capture generates $35K-50K/year. Zero patient cost-share increases participation. Only 50% of eligible patients get AWVs — proactive scheduling doubles revenue.
Cognitive assessment (99483): Pays $250-350 per assessment. Can be billed with AWV on same date. With 30% of geriatric patients having cognitive concerns, 60 assessments/year = $15K-21K/year additional.
Advance care planning (99497/99498): $80-115 per session. Can be billed annually. With 100 Medicare patients = $8K-11.5K/year. Zero patient cost-share when billed with AWV.
Chronic care management: 99490 pays $42-74/month. Average geriatric patient has 4-6 chronic conditions = easily qualifies. With 100 enrolled patients = $50K-89K/year.
Home visits: 99349/99350 pay $200-350 per visit. Growing demand as value-based care rewards keeping patients out of hospitals. House call practices with 8-10 home visits/day = $400K-700K/year.
Nursing facility management: 99307-99310 pays $80-150 per visit x monthly x 30 residents = $29K-54K/year per facility. Medical directorship adds $2K-5K/month.
Documentation Checklist
What the chart must contain to support billing. Missing documentation means audit vulnerability.
- Annual Wellness Visit (G0438/G0439): Document Health Risk Assessment (HRA), review of functional status, fall risk assessment, depression screening (PHQ-2/9), cognitive screening (Mini-Cog, MoCA, or MMSE), visual acuity, hearing assessment, medication reconciliation, advance care planning status, and personalized prevention plan.
- Cognitive assessment (99483): Document full cognitive evaluation — standardized instrument used (MoCA, SLUMS, MMSE), score and interpretation, functional assessment (ADLs/IADLs), behavioral assessment (NPI), caregiver input, safety evaluation (driving, home safety, wandering risk), and care plan including referrals.
- Home visits (99341-99350): Document reason for home visit (homebound status required for Medicare), home environment assessment, fall hazards, medication review (bedside med review), functional status, caregiver assessment, and home safety recommendations.
- Nursing facility (99304-99318): Document admission assessment (99304-99306), subsequent visits (99307-99310), and annual assessment (99318). Each visit: problem list, medication review, functional status, advance directives, and discharge planning.
- Advance care planning (99497/99498): Document discussion participants (patient, family, healthcare proxy), topics covered (code status, hospitalization preferences, artificial nutrition, hospice discussion), patient values and goals, and resulting documentation (POLST, advance directive, healthcare proxy designation).
Coding Workflow
Step by step approach for coding geriatric medicine encounters correctly.
1. Determine encounter type: office E/M (99213-99215), AWV (G0438/G0439), home visit (99341-99350), nursing facility (99304-99318), or cognitive assessment (99483). 2. For AWV: complete ALL required components (HRA, fall risk, depression screen, cognitive screen, med review, prevention plan). Missing any component = audit failure. 3. For complex geriatric patients: consider CCM (99490/99491), TCM (99495/99496), and ACP (99497/99498) — each separately billable when criteria are met. 4. For dementia patients: bill 99483 annually for comprehensive cognitive assessment. Can be billed with AWV on same date. 5. For homebound patients: home visit codes (99341-99350) — document homebound status (leaving home requires considerable effort). 6. For nursing facility: monthly visits required (99307-99310). Annual assessment (99318) once per year.
