Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with chronic post-stroke aphasia is referred to outpatient speech-language pathology for evaluation and ongoing therapy under the Merit-based Incentive Payment System (MIPS) specialty set for speech-language pathology. The clinical workflow begins with a comprehensive speech-language evaluation, including standardized language and cognitive-communication assessments, swallowing screening, and functional communication goals documented in the medical record. The speech-language pathologist (SLP) performs individualized therapy sessions focusing on language restoration, compensatory strategies, and caregiver training. Progress is measured with validated outcome instruments at baseline and at scheduled intervals to satisfy MIPS reporting requirements. Typical visits occur in outpatient rehabilitation clinics, hospital-based outpatient therapy departments, long-term acute care facilities, or skilled nursing facilities when the patient requires facility-based services. Documentation includes diagnosis linkage, therapy plan of care, timed therapy units when applicable, objective outcome scores, and any use of modifiers for unusual circumstances or facility-specific billing requirements.
