What 01937 covers
This anesthesia service accompanies percutaneous, image-guided injection, drainage, or aspiration involving the cervical or thoracic spine or spinal cord. An anesthesia professional reports the anesthesia service while the proceduralist reports the intervention.
Choose 01937 for cervical or thoracic work in this category; 01938 is the lumbar or sacral counterpart. Cervical or thoracic procedures using a neurolytic agent or involving neuromodulation or intervertebral work belong to the corresponding anesthesia categories instead. The record should establish the spinal region, percutaneous image-guided approach, intervention performed, and anesthesia start and end times. The code has 4 base units. Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. Anesthesia time is reported in minutes and converted to 15-minute units computed to one decimal place; it starts with patient preparation for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.

01937 billing questions
When should 01937 be selected instead of 01938?
Use 01937 for the specified percutaneous image-guided injection, drainage, or aspiration procedures in the cervical or thoracic region. Use 01938 for the lumbar or sacral region.
How does 01937 differ from anesthesia for neurolytic procedures?
01937 covers the injection, drainage, or aspiration category. Procedures involving a neurolytic agent in the cervical or thoracic region are represented by 01939.
Does 01937 report the spinal intervention or the anesthesia?
It reports the anesthesia service; the proceduralist reports the spinal intervention. The anesthesia record should support the service and its time.
What should the anesthesia and procedure records show?
Document the cervical or thoracic region, percutaneous image-guided approach, and whether the intervention was an injection, drainage, or aspiration. The anesthesia record should identify the provider and show the start and end times.
How are Medicare anesthesia units calculated for 01937?
The code has 4 base units, and Medicare payment uses base units plus time units multiplied by the locality’s anesthesia conversion factor. Time is converted from minutes into 15-minute units computed to one decimal place.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
