Geriatric medicine claim denial checks
Geriatric medicine claim denial review should confirm Medicare or payer eligibility, E/M documentation, ICD-10 chronic condition support, medical necessity, modifier logic, EOB or ERA reason, corrected claim need, and appeal deadline before resubmission.
CMS PFS, ICD-10, NCCI, electronic billing, and review reason code resources support payment validation, diagnosis support, edit review, claim workflow, and denial interpretation.

Geriatric Medicine Denial Patterns
Geriatric medicine denial rates typically run 4% to 7% for E/M claims and 8% to 12% for non-encounter codes (CCM, TCM, AWV). The higher denial rate on non-encounter codes reflects the more complex documentation and timing requirements these codes carry. Each non-encounter code has specific eligibility criteria, time thresholds, and documentation elements that must all be met simultaneously. Missing any single element triggers a denial. The financial impact is significant because non-encounter codes represent 30% to 40% of geriatric practice revenue.
Denial Reason 1: AWV Timing Violations
Billing an AWV within 11 months of the previous AWV is the most common geriatric-specific denial. Medicare requires a full 12-month interval between AWVs. The denial appears as a coverage rejection rather than a coding error. This denial is 100% preventable with a scheduling system that checks the patient last AWV date before allowing a new AWV to be scheduled. A related timing error is billing G0438 (initial AWV) when the patient has already received an initial AWV in a prior year. After the first G0438, all subsequent AWVs should be billed as G0439, regardless of whether the patient has changed providers.
Denial Reason 2: CCM Documentation Gaps (CARC 16)
CARC 16 (missing information) on CCM claims typically means that the documentation does not support the minimum time threshold or the required care coordination activities are not documented. CCM requires at least 20 minutes of clinical staff time per month for 99490. The time must be documented with specific activities: what was done, when it was done, and the cumulative time for the month. “Called patient to check on medications, 15 minutes” is not sufficient if the cumulative total does not reach 20 minutes. Each CCM encounter must also be linked to the patient chronic condition care plan. Without a documented, active care plan, the CCM claim lacks the clinical foundation required for payment.
Denial Reason 3: TCM Missed Deadlines (CARC 29)
CARC 29 (time limit for filing has expired) and related denials appear when TCM timing requirements are not met. TCM requires interactive contact within 2 business days of discharge and a face-to-face visit within 7 days (99496) or 14 days (99495). If either deadline is missed, the TCM code cannot be billed. The most common failure point is the 2-business-day contact requirement because discharge notifications are often delayed. If the practice does not learn about the discharge until day 3 or later, the TCM opportunity is lost. Even if the face-to-face visit occurs within the window, the initial contact deadline must also be met.
Denial Reason 4: Cognitive Assessment Incomplete Elements (CARC 16)
Code 99483 requires all specified documentation elements. If any element is missing (standardized cognitive test score, functional assessment, medication reconciliation, neuropsychiatric evaluation, safety assessment, caregiver assessment, care plan), the claim may be denied on audit or downgraded to a standard E/M level. The most commonly missed elements are the caregiver needs assessment (often overlooked when no caregiver accompanies the patient) and the written care plan (sometimes the physician discusses the plan verbally but does not document it in writing). Use a checklist template that requires all elements to be completed before the encounter can be closed.
Denial Reason 5: AWV Combined with Preventive Visit Code
Billing both an AWV (G0438/G0439) and a preventive medicine visit code (99385-99397) on the same date results in denial of one or both claims. The AWV is a Medicare benefit that replaces the standard preventive visit for Medicare patients. You cannot bill both. This error typically occurs when the billing system defaults to a preventive visit code based on patient age and the AWV code is added manually, creating a duplicate preventive claim. Configure the billing system to prevent concurrent submission of AWV and preventive visit codes for the same patient on the same date.
Preventing Geriatric Medicine Denials
Five systems prevent the majority of geriatric-specific denials: an AWV eligibility checker that verifies the 12-month interval before scheduling, a CCM time tracking system that alerts when the 20-minute threshold has not been reached before the end of the month, a TCM discharge notification workflow that triggers the 2-business-day contact window, a 99483 documentation checklist with mandatory completion of all elements, and a billing system edit that prevents concurrent AWV and preventive visit code submission. Implement these as hard stops in the workflow so that claims cannot be generated when requirements are not met.
