Summary & Overview
HCPCS G2107: Frailty with Advanced Illness in Older Adults
HCPCS Level II code G2107 designates patients aged 66 and older with at least one documented encounter for frailty during the measurement period and an advanced illness diagnosis either during that period or in the prior year. As a population-identification code, G2107 matters nationally for quality measurement, care coordination, and stratifying high-risk older adults for services and program eligibility. Its use supports tracking of frailty and advanced illness prevalence among older Medicare-age populations and informs resource allocation and program design.
Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical scope and service context, the primary payers that commonly encounter this code, and the practical implications for measurement and administrative reporting. The report outlines where this code typically appears in clinical workflows (outpatient and ambulatory encounters) and what gaps exist in the input data.
What readers will learn: a clear description of what G2107 represents; which national payers are relevant for coverage and reporting; the service line and typical sites of service; and a summary of missing or unavailable data elements in the source input. Data not available in the input are identified explicitly where applicable.
Billing Code Overview
HCPCS Level II code G2107 identifies patients 66 years of age and older who have at least one claim or encounter for frailty during the measurement period and an advanced illness diagnosis either during the measurement period or in the year prior. The code captures a clinical cohort defined by age, a frailty encounter, and concurrent or recent advanced illness.
-
Service type: Population/quality measure identification and patient cohort classification for advanced illness and frailty
-
Typical site of service: Outpatient encounters, ambulatory care settings, and any clinical encounter where frailty and advanced illness diagnoses are documented
Clinical & Coding Specifications
Clinical Context
A typical patient is a 78-year-old Medicare beneficiary with progressive functional decline, unintentional weight loss, decreased gait speed, and frequent falls. During a primary care or geriatric clinic visit the clinician documents frailty using standardized assessment elements (e.g., gait speed, weight loss, exhaustion, low activity, weakness) and also documents an advanced illness diagnosis such as metastatic cancer, advanced heart failure, end-stage chronic obstructive pulmonary disease, or advanced dementia that occurred during the measurement period or in the prior year. The clinical workflow includes: a medication and problems review, focused physical examination (mobility, grip strength), frailty screening instrument or documentation of frailty phenotype, reconciliation of goals of care, and coding the visit to reflect frailty and advanced illness for quality measurement and reporting. Typical sites of service are outpatient primary care clinics, geriatric clinics, home health visits, and long-term care or skilled nursing facility encounters where assessment and documentation of frailty and advanced illness occur. The service type is an assessment/documentation encounter for identification of frailty in an older adult with concurrent advanced illness for measurement and quality reporting purposes. Typical modifiers applied to claims for the encounter may reflect unusual service circumstances, place of service distinctions, or clinical staff involvement as appropriate for the visit.
