Summary & Overview
CPT 61545: Craniotomy for Craniopharyngioma Resection
CPT code 61545 captures an open neurosurgical craniotomy performed to remove a craniopharyngioma located near the pituitary gland and often involving the hypothalamus. This high-complexity intracranial tumor resection has substantial clinical and resource implications because of the tumor’s proximity to critical neuroendocrine structures and the need for skilled neurosurgical, anesthetic, and postoperative critical care teams.
Key payers addressed in the national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise context on the clinical indication and typical care setting, plus what to expect in benchmarking and policy coverage discussions: common site-of-service considerations (hospital inpatient operating room and possible ICU), drivers of cost and utilization (operative complexity, length of stay, perioperative monitoring, and multidisciplinary care), and areas of policy attention such as authorization criteria and medical necessity determinations for complex intracranial tumor resections.
The report provides benchmarks where available, notes recent payer policy trends affecting high-complexity neurosurgical procedures, and situates CPT code 61545 within clinical workflows for neurosurgery and neuro-oncology teams. Data not available in the input will be noted explicitly in relevant sections.
Billing Code Overview
CPT code 61545 describes a neurosurgical procedure in which the surgeon removes a portion of the skull (craniotomy) to excise a craniopharyngioma, a benign but locally aggressive tumor that develops near the pituitary gland and commonly extends into the hypothalamus. The procedure is a tumor resection of the sellar/suprasellar region and focuses on safe removal of tumor tissue while preserving nearby neurovascular and endocrine structures.
Service type: Open neurosurgical tumor resection (craniotomy for intracranial tumor removal)
Typical site of service: Hospital operating room (inpatient neurosurgery service), with perioperative care in the hospital and possible intensive care unit monitoring postoperatively.
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents with progressive visual field deficits, headaches, and endocrine dysfunction (panhypopituitarism and growth hormone deficiency). MRI demonstrates a sellar/suprasellar mass consistent with a craniopharyngioma compressing the optic chiasm and extending into the hypothalamic region. Neurosurgery elects an open transcranial approach requiring a craniotomy to resect the tumor. Preoperative workflow includes neurosurgical and neuroendocrine consultation, imaging (MRI brain with and without contrast), baseline pituitary hormone panels, and informed consent discussing risks of pituitary dysfunction and hypothalamic injury. On the day of surgery, the patient undergoes general endotracheal anesthesia; intraoperative neuronavigation and microsurgical techniques are used. The surgeon performs a craniotomy, partial skull bone removal to access and excise the craniopharyngioma, with possible cerebrospinal fluid diversion or reconstruction of the skull base as needed. Postoperatively the patient is monitored in a neurocritical care or step-down unit, undergoes serial neurologic and endocrine assessment, and receives imaging to evaluate resection extent. Rehabilitation, endocrinology follow-up, and, if indicated, radiation oncology consultation for residual or recurrent disease occur in the outpatient period.
