Billing Code Overview

HCPCS Level II code G0153 describes services performed by a qualified speech‑language pathologist in the home health or hospice setting, billed in 15‑minute increments. The code applies to skilled speech‑language pathology interventions delivered to patients in a home health or hospice environment and captures time-based therapeutic or rehabilitative contact provided directly by a credentialed clinician.

Service Type: Speech‑Language Pathology (Home Health/Hospice)

Typical Site of Service: Home health or hospice setting (HCPCS Level II “G” code billing)

Clinical Context

A homebound adult patient with post-stroke dysphagia and expressive language deficits receives skilled speech-language pathology visits at home. The patient is evaluated by a qualified speech-language pathologist who documents baseline swallow function, communication needs, and an individualized plan of care. Treatment sessions occur in the patients residence during a home health episode or under hospice services; each 15-minute block of direct speech-language pathology intervention is coded with HCPCS Level II code G0153. Typical workflow includes assessment, goals review, direct therapy (e.g., compensatory swallowing strategies, communication device training), caregiver education, and documentation of time per 15-minute unit for billing.

Coding Specifications

• Common modifiers listed:

• GN : Services delivered under an outpatient speech-language pathology plan of care. Use when the speech-language pathology services are provided under an outpatient SLP plan of care even if delivered in the home/hospice setting.

• 59 : Distinct Procedural Service. Use when a separate, distinct service is provided that is not normally bundled with other services on the same date; supports billing G0153 when a separate, unrelated procedure is performed during the same visit.

• Associated provider taxonomies and specialties:

• 235Z00000X : Speech-Language Pathologist — clinicians who evaluate and treat swallowing, speech, language, voice, and augmentative/alternative communication needs.

• 251E00000X : Home Health Agency — organizations that provide skilled services, including speech-language pathology, in the home setting.

• 253Z00000X : In Home Supportive Care — providers or organizations delivering supportive and skilled services in the patients home.

Related Codes

• G0161 : Services performed by a qualified speech‑language pathologist in the home health setting, in the establishment or delivery of a safe and effective speech‑language pathology maintenance program, each 15 minutes. — Used for maintenance program establishment or delivery; may be billed in the home health setting as a related home SLP service.

• 92507 : Speech/hearing treatment; direct (eg, articulation, language, voice, etc.) (Specifically noted as re‑evaluation code alternative). — Outpatient therapy code for direct SLP treatment; can be an alternative for ongoing therapy documentation when appropriate.

• 92607 : Evaluation for prescription for speech generating device; selection, fitting and training. — Evaluation related to prescribing and training with speech-generating devices; relates to device-related entries such as Z96.3.

• 92609 : Evaluation for prescription for speech generating device; adaptation of devices and training. — Device adaptation and training evaluation; used when device adjustments or customization are required.

• 92597 : Evaluation for use and/or effect of speech‑generating device — Functional evaluation of a speech-generating device in the patients communication environment.

• Clinical workflow relationships and common usage:

• G0161 and G0153 are both home-based SLP HCPCS services; G0161 is focused on maintenance program establishment while G0153 describes direct treatment time in 15-minute units.

• 92507 is commonly used in outpatient settings and may serve as an alternative code for direct therapy when documentation supports outpatient therapy billing.

• 92607, 92609, and 92597 are evaluations specific to speech-generating devices and are commonly used alongside G0153 when device prescription, fitting, adaptation, or evaluation occur during the course of home SLP care.
