CPT Code 96105: Assessment of Aphasia

Introduction

CPT Code 96105 is used for the assessment of aphasia, a condition that affects a person's ability to communicate due to brain damage, often caused by a stroke, traumatic brain injury (TBI), or neurological disorders such as dementia. This code covers a standardized evaluation conducted by speech-language pathologists (SLPs) to measure language comprehension, expression, reading, and writing skills.

Proper documentation and accurate billing of CPT 96105 are essential for ensuring reimbursement from Medicare, Medicaid, and private insurance while supporting effective treatment planning for individuals with language impairments.

Importance of CPT 96105 in Medical Billing and Coding

• Supports insurance claims for speech-language evaluations.
• Justifies the need for speech therapy services in patients with neurological conditions affecting communication.

Case Studies

Real-World Applications of CPT 96105

Case 1: Post-Stroke Aphasia Assessment

Scenario: A 62-year-old stroke survivor struggled with expressive aphasia and comprehension issues. His neurologist recommended a CPT 96105 assessment to determine his language deficits.

Process:

• Standardized tests (BDAE, WAB) measured speech fluency, comprehension, and writing skills.
• Results showed moderate expressive aphasia with naming difficulties and grammatical errors.
• A personalized speech therapy plan was created, focusing on verbal exercises and AAC (alternative communication).

Outcome: The detailed report justified Medicare coverage, ensuring continued therapy sessions.

Case 2: Cognitive Decline & Primary Progressive Aphasia (PPA)

Scenario: A 70-year-old retired teacher experienced gradual speech decline, struggling with word-finding and sentence formation.

Process:

• CPT 96105 testing identified progressive non-fluent aphasia with intact comprehension but poor speech production.
• Speech therapy was introduced to slow deterioration and improve communication strategies.

Outcome: The assessment report secured insurance coverage, ensuring ongoing therapy support under Medicare.

Common Billing Mistakes and How to Avoid Them

Frequent Claim Denials & Errors

• Missing documentation of standardized testing results.
• Incorrect ICD-10 coding, leading to claim rejection.
• Billing CPT 96105 alongside 92507 (speech therapy) without proper justification.

Strategies to Prevent Errors

• Always include test scores, patient history, and treatment recommendations.
• Ensure CPT 96105 is billed separately from therapy sessions unless modifier 59 is used.

Conclusion

CPT 96105 plays a vital role in diagnosing aphasia and language disorders, guiding speech therapy interventions, and securing insurance coverage for treatment. Proper documentation, coding accuracy, and adherence to billing best practices can help maximize reimbursement and improve patient outcomes.
