Summary & Overview
HCPCS G8942: Functional Outcome Assessment with Timely Care Plan
HCPCS Level II code G8942 documents a standardized functional outcome assessment completed within the prior 30 days and the creation of a care plan addressing identified deficiencies within two days. The code captures time-sensitive, outcome-oriented documentation that supports coordinated functional care across outpatient, home health, and rehabilitation settings. Nationally, G8942 matters because it aligns clinical documentation with care planning workflows that can influence quality measurement, care coordination, and appropriate reimbursement for assessment-driven services. Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn what the code represents clinically and operationally, which payers commonly cover the service, and what gaps exist in the available metadata. The publication provides benchmarks and policy context where available, explains typical sites of service and service type, and notes common billing modifiers. It also highlights areas where additional payer guidance or coding clarification may be required. Data not available in the input is indicated where applicable.
Billing Code Overview
HCPCS Level II code G8942 describes documentation of a functional outcome assessment using a standardized tool within the prior 30 days, with a care plan based on identified deficiencies documented within two days of that assessment. The service represents assessment-driven care planning focused on functional status deficits.

Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult recently discharged from an inpatient stay for exacerbation of chronic obstructive pulmonary disease or after a fall-related admission who requires a documented functional outcome assessment and timely care planning. Within 30 days, a clinician or allied health professional (for example, a physical therapist, occupational therapist, nurse case manager, or physician) administers a standardized functional outcome tool such as the Barthel Index, AM-PAC (Activity Measure for Post-Acute Care), or PROMIS physical function and documents the results in the medical record. Within two days of that assessment the clinician or interdisciplinary team documents a care plan that addresses identified deficits (mobility, self-care, fall risk, ADL/IADL needs), assigns responsible providers, specifies interventions (therapy orders, durable medical equipment, home health referral), and sets measurable goals. Typical sites of service include inpatient hospitals, skilled nursing facilities, long-term acute care hospitals, home health settings, outpatient rehabilitation clinics, and transitional care programs. The patient scenario often triggers when transition-of-care workflows or post-acute quality measures require a standardized functional assessment and a timely care plan to support safe discharge, reduce readmission risk, and coordinate post-discharge services. Common payors involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
