CPT 96105: Evaluation for Aphasia and Communication Ability
CPT code 96105 represents a clinician-conducted evaluation specifically for aphasia, a communication disorder commonly caused by stroke or traumatic brain injury. As a targeted diagnostic assessment, the code captures structured testing of a patient’s receptive and expressive language abilities to guide diagnosis, therapy planning, and coordination with neurology or speech-language pathology services. Nationally, accurate coding for aphasia evaluations supports appropriate clinical pathways for post-stroke and neuro-oncology populations and informs resource allocation for speech and language services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A 68-year-old right-handed patient presents to an outpatient neurology clinic three weeks after an ischemic stroke involving the dominant hemisphere with persistent word-finding difficulty, impaired comprehension of complex sentences, and reduced verbal expression. The patient is referred by the treating neurologist for a formal speech-language evaluation to characterize the type and severity of aphasia, document baseline communication function, and guide rehabilitation planning. The evaluation is performed by a licensed speech-language pathologist in an outpatient rehabilitation clinic or hospital-based speech pathology suite and includes standardized aphasia testing, conversational speech sampling, reading and writing tasks, and caregiver interview. Results are documented in the medical record and communicated to the referring neurologist and rehabilitation team to inform therapy frequency and goals. Typical sites of service include outpatient rehabilitation clinics, hospital outpatient departments, inpatient rehabilitation units, and skilled nursing facilities when speech-language pathology services are provided at the bedside.
