The ICD-10 code for left-sided weakness due to a Cerebrovascular Accident (CVA), commonly known as a stroke, requires careful consideration. While the specific code can vary depending on the details of the patient's condition, a common code used is often related to hemiplegia and hemiparesis following a stroke. It's crucial to consult the ICD-10 manual or a qualified medical coder for accurate and specific coding based on the patient's documentation. Accurate coding is essential for proper billing and tracking of medical conditions.
