G9170 Memory Functional Limitation — HCPCS Reimbursement

HCPCS Level II code G9170 represents documentation of a patient’s memory functional limitation at discharge from therapy or at the end of a reporting period. This administrative measure captures cognitive functional status rather than a discrete therapeutic procedure, and it supports continuity of care, outcomes tracking, and quality reporting across therapy and post-acute care settings. Nationally, consistent use of this code assists payers and providers in tracking cognitive recovery and aligning discharge planning with patient needs.

Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code signifies, the typical care settings where it is used, and the policy and billing context that affect reporting. The publication outlines benchmarking considerations, documentation requirements relevant to reimbursement and quality programs, and clinical context linking memory functional limitation assessment to therapy discharge processes. It also summarizes common reporting challenges and points of alignment with national quality measurement efforts. Data not available in the input will be clearly marked where applicable.

Billing Code Overview

HCPCS Level II code G9170 denotes memory functional limitation, discharge status at discharge from therapy or to end reporting. This code is used to document the patient's level of memory-related functional impairment at the point of discharge from a therapeutic course or at the end of a reporting period.

Service type: Functional status assessment focused on memory limitations
Typical site of service: Outpatient therapy settings, rehabilitation facilities, home health therapy visits, or other care settings where therapy discharge or reporting occurs

Data not available in the input.

Clinical Context

A 78-year-old patient with progressive cognitive decline completes an episode of outpatient speech-language pathology and occupational therapy focused on compensatory strategies for memory deficits and functional independence. At discharge from therapy, the clinician documents the patient’s memory functional limitation level to report outcomes and finalize the plan of care. The workflow includes a standardized functional assessment (e.g., Cognitive Functional Independence Measure or a facility-specific memory assessment), interdisciplinary review of progress toward goals, notation of discharge cognitive status in the therapy discharge summary, and submission of the discharge functional limitation code for quality reporting and reimbursement purposes. The patient scenario typically occurs in an outpatient rehabilitation clinic, skilled nursing facility, or inpatient rehabilitation setting at the time therapy services end or when facility reporting periods close.

Coding Specifications

Modifier	Description	When to Use
`59`	Distinct procedural service	Use when a separate, distinct service unrelated to other therapy interventions is provided and needs separate billing distinction.
`76`	Repeat procedure by same physician

Taxonomy Code	Specialty	Notes
`225100000X`	Physical Therapist	PTs commonly participate in functional discharge reporting in rehabilitation settings.
`225200000X`	Occupational Therapist	OTs frequently assess memory-related functional limitations and document discharge status.
`352S00000X`	Speech-Language Pathologist	SLPs evaluate and report memory and cognitive-communication functional limitations at discharge.
`208D00000X`	Neurologist	Neurology may contribute to cognitive assessment and discharge diagnoses when memory impairment is neurologic in origin.
`208000000X`	Family Medicine Physician	Primary care physicians often coordinate discharge plans and review functional limitation documentation.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`G31.84`	Mild cognitive impairment, so stated	Common diagnosis for patients receiving therapy targeting memory function; supports documentation of memory functional limitation at discharge.
`F02.80`	Dementia in other diseases classified elsewhere without behavioral disturbance, unspecified	Frequently associated with memory functional limitations reported at therapy discharge.
`F03.90`	Unspecified dementia without behavioral disturbance	Often used when dementia is present and therapy documents functional memory impairment at discharge.
`R41.3`	Other amnesia	Relevant when specific memory loss is the primary functional limitation addressed in therapy and reported at discharge.
`I69.398`	Other sequelae of unspecified cerebrovascular disease; cognitive deficits following stroke	Cognitive and memory limitations post-stroke are commonly assessed and reported at discharge from therapy.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`97112`	Therapeutic procedure, therapeutic activities, direct (one-on-one) patient contact by the provider, focusing on functional performance	Commonly provided during the therapy episode addressing functional deficits that include memory-related compensatory strategies prior to discharge.
`97127`	Therapeutic procedures, cognitive skills development (e.g., attention, memory, problem solving)	Directly targets memory and cognitive functions and is commonly billed during the course of therapy before discharge reporting.
`92507`	Treatment of speech, language, voice, communication, and/or auditory processing disorder; individual	Speech-language pathology interventions for memory-related communication deficits often precede the discharge functional limitation report.
`97161`	Physical therapy evaluation: low complexity	Initial PT evaluation codes used at therapy episode start; results inform discharge functional limitation documented by `G9170`.
`97162`	Physical therapy evaluation: moderate complexity	Used for more complex evaluations that guide treatment plans whose outcomes are summarized at discharge.
