Noridian has also noted that providers have been using both CPT codes 64999 (unlisted procedure nervous system) and 64445 (Injection anesthetic agent; sciatic nerve, single) for the injection of the piriformis muscle and surrounding muscle groups. This is not the correct way to code.
Right sided piriformis syndrome. ICD-10-CM G57.01 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0): 073 Cranial and peripheral nerve disorders with mcc. 074 Cranial and peripheral nerve disorders without mcc. Convert G57.01 to ICD-9-CM.
The December 2011 CPT Assistant1 clarifies that sciatic nerve injection (64445) should not be used to report a piriformis injection as the work involved in a sciatic nerve injection is substantially more than that which is required in a piriformis injection.
Under radiologic guidance (fluoroscopy or ultrasound imaging) the provider injects an anesthetic agent such as bupivacaine or lidocaine into the piriformis muscle.
A piriformis steroid injection is an injection of a long lasting steroid into the piriformis muscle of your buttock. This muscle attaches to the side of the sacrum, which is the side, flat bone at the base of your spine just above your tailbone.
G57. 01 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM G57. 01 became effective on October 1, 2021.
Piriformis takes its origin from the anterior surface of the second to fourth sacral vertebrae, greater sciatic notch and sacrotuberous ligament. It exits the pelvis through the greater sciatic foramen and inserts as a rounded tendon into the upper border of the greater trochanter.
The correct code for this condition, as answered in AHA's Coding Clinic, is 355.0.
Coding Clarification When the clinical notes reflect direct nerve block to the sciatic nerve, 64445 should be used. When the injection focus is in the piriformis muscle or surrounding muscle groups, 20552 should be used.
Piriformis muscle injection(s) should be reported using CPT code 20552, Injection(s); single or multiple trigger point(s), 1 or 2 muscle(s).
Description. Piriformis is a flat muscle and the most superficial muscle of the deep gluteal muscles. It is part of the lateral rotators of the hip (obturator internus, superior and inferior gemelli, quadratus femoris, obturator externus, and gluteus maximus).
So – to summarise – the main difference between piriformis syndrome and sciatica is that piriformis syndrome is mostly local buttock pain and in worse cases some leg pain. Sciatica is typified with lower back pain, buttock pain and leg pain which tracks down the back of the leg.
Pelvic floor myalgia and other disorders of the pelvic floor musculature, such as piriformis syndrome, are often identified by a medical history and single-digit examination of the pelvic floor.
Currently, there are two codes for sciatic injections: CPT code 64445 for a single injection and CPT code 64446 for a catheter insertion. However, many anesthesia practitioners now use a popliteal approach for sciatic injections.
Although there isn't a specific ICD-10-CM code for pain in the buttock, you can use M79. 1 Myalgia. In the clinical description for M79.
ICD-Code M54. 3 is a non-billable ICD-10 code used for healthcare diagnosis reimbursement of Sciatica.
