Why Geriatric Practices Consider Outsourcing
Geriatric medicine billing combines standard E/M coding with Medicare-specific codes (AWV, CCM, TCM, advance care planning) that require specialized knowledge of timing rules, documentation requirements, and eligibility criteria. Many general medical billing companies lack expertise in these geriatric-specific codes, leading to missed revenue and compliance errors. A geriatric practice that outsources to a vendor without CCM and TCM experience may lose 20% to 35% of its potential non-encounter revenue simply because the vendor does not know how to bill these codes or does not have workflows to capture the required documentation.
Cost Comparison: In-House vs. Outsourced
In-house billing for a 2 to 3 physician geriatric practice requires 1.5 to 2.5 billing staff: one medical coder familiar with geriatric codes, one claims and AR specialist, and a part-time CCM billing coordinator (if CCM is billed in-house). Total annual cost: $120,000 to $200,000. Outsourced billing typically charges 5% to 8% of collected revenue. A geriatric practice collecting $800,000 to $1.5 million annually pays $40,000 to $120,000 for outsourced billing. The critical variable is whether the vendor handles non-encounter code billing (CCM, TCM) or only processes encounter-based claims. Some vendors charge an additional per-patient monthly fee for CCM billing management.
Vendor Evaluation for Geriatric Billing
Evaluate vendors on five geriatric-specific competencies. First, AWV billing accuracy: the vendor must track 12-month eligibility intervals and prevent duplicate AWV billing. Ask for their AWV denial rate (should be below 3%). Second, CCM billing expertise: the vendor must understand CCM consent requirements, time tracking, and monthly billing cycles. Third, TCM billing: the vendor must have a workflow for tracking hospital discharges and meeting the 2-day/7-day/14-day deadlines. Fourth, advance care planning billing: the vendor must know when 99497 can be billed with the AWV (no cost-sharing) versus separately (with cost-sharing). Fifth, Medicare-specific knowledge: the vendor must understand Medicare supplemental insurance coordination, Medicare Advantage billing differences, and MIPS quality reporting integration.
CCM Billing: In-House vs. Vendor
CCM billing can be handled by the billing vendor or kept in-house. The clinical care coordination (phone calls, medication management, care plan updates) is always performed in-house by clinical staff. The billing question is who handles consent tracking, time documentation review, monthly claim generation, and CCM payment posting. Vendors that specialize in geriatric billing can manage the entire CCM billing cycle, reviewing time logs weekly to ensure the 20-minute threshold is met before month-end and generating claims automatically. If the vendor handles CCM billing, ensure they provide monthly CCM enrollment reports showing active patients, time logged, and claims submitted.
Transition Considerations
Transitioning geriatric billing requires transferring four types of data to the new vendor: active patient insurance information, AWV completion dates for the entire Medicare panel (to prevent early rebilling), CCM enrollment status and consent dates for all CCM patients, and TCM active cases (patients currently in the 30-day post-discharge window). A 60 to 90 day transition period is necessary. During the overlap, the old vendor processes claims for encounters before the transition date and the new vendor processes claims for encounters after the transition date. CCM billing for the transition month must be assigned to one vendor only to prevent duplicate billing.
Performance Metrics for Geriatric Billing Vendors
Set performance standards that include both standard billing metrics and geriatric-specific KPIs. Standard metrics: clean claim rate 97%+, denial rate below 6%, AR days below 30, net collection rate 95%+. Geriatric-specific metrics: AWV denial rate below 3%, CCM claims submitted by the 5th of each month, TCM capture rate reported monthly, zero AWV timing violations, and monthly reporting on non-encounter revenue as a percentage of total collections. The vendor should also track and report the number of eligible patients not currently enrolled in CCM, creating a pipeline for enrollment growth.
