What is the CPT (Current Procedural Terminology) code for a ganglion impar block?

From the Research

The CPT code for a ganglion impar block is 64451, which specifically describes injection(s) of anesthetic and/or steroid into the sacrococcygeal junction, where the ganglion impar is located. This procedure is typically used to treat chronic perineal, rectal, or coccygeal pain, as supported by studies such as 1, which compared radiofrequency thermocoagulation of ganglion Impar with block using a combination of local anaesthetic and steroid for management of chronic perineal pain. The code includes the injection procedure itself, regardless of whether it is performed under fluoroscopic or CT guidance. However, if imaging guidance is used, you would also report the appropriate imaging guidance code (such as 77003 for fluoroscopic guidance) in addition to the primary procedure code, as noted in 2, which described the feasibility of ultrasound in assisting ganglion impar blocks.

Key Points to Consider

• The ganglion impar block is a procedure used to treat chronic perineal, rectal, or coccygeal pain, as discussed in 3 and 4.
• The CPT code 64451 includes the injection procedure itself, regardless of the guidance method used.
• Imaging guidance, such as fluoroscopy or ultrasound, may be used to assist with the procedure, as described in 2 and 5.
• Documentation should include the indication for the procedure, medications injected, and any guidance method used.

Important Considerations for Coding and Billing

• The CPT code 64451 is the primary code for the ganglion impar block procedure.
• Additional codes may be reported for imaging guidance, such as 77003 for fluoroscopic guidance.
• Accurate documentation is essential for correct coding and billing, as emphasized in 1 and 4.
