Malignant neoplasm of unspecified acoustic nerve
ICD-10 C72.40 is a billable code used to indicate a diagnosis of malignant neoplasm of unspecified acoustic nerve.
C72.40 refers to a malignant neoplasm affecting the acoustic nerve, which is responsible for hearing and balance. This neoplasm can arise from various cellular origins, including Schwann cells, leading to conditions such as vestibular schwannoma (acoustic neuroma). The acoustic nerve, or cranial nerve VIII, is located in the central nervous system (CNS) and is crucial for auditory processing and equilibrium. Symptoms may include hearing loss, tinnitus, and balance disturbances. Imaging studies, particularly MRI, are essential for diagnosis, allowing visualization of the tumor's size, location, and potential impact on surrounding structures. Molecular markers, such as mutations in the NF2 gene, may be investigated, especially in cases of familial syndromes like Neurofibromatosis Type II. Neurological function can be significantly affected, necessitating a multidisciplinary approach for management, including surgical intervention, radiation therapy, and rehabilitation. Accurate coding is vital for appropriate treatment planning and reimbursement.
Detailed audiological assessments, imaging reports, and surgical notes.
Evaluation of patients with hearing loss and balance issues, pre- and post-operative assessments.
Ensure clear documentation of symptoms and imaging findings to support the diagnosis.
Operative reports, pathology results, and follow-up notes.
Surgical intervention for tumor resection, management of complications.
Document the extent of resection and any neurological deficits post-surgery.
Used in cases where surgical intervention is required for malignant tumors.
Operative report detailing the procedure and findings.
Neurosurgeons must document the extent of resection and any complications.
MRI is the preferred imaging modality for diagnosing malignant neoplasms of the acoustic nerve, providing detailed visualization of the tumor's characteristics.
