CPT® Code 61563

The procedure described by CPT® Code 61563 involves the surgical excision of a benign tumor located in the cranial bone, which may include conditions such as fibrous dysplasia. This operation is performed both intra- and extracranially, meaning that the surgeon accesses the tumor from both inside the skull and from the outside, depending on the tumor's location and size. The primary goal of this procedure is to remove the tumor while preserving surrounding structures and minimizing damage to the cranial bone. It is important to note that this specific code is used when the excision does not involve decompression of the optic nerve. If optic nerve decompression is required during the procedure, CPT® Code 61564 should be utilized instead. This distinction is crucial for accurate coding and billing, as it reflects the complexity and extent of the surgical intervention performed.
