Typical piriformis syndrome symptoms may include:
With prompt diagnosis and treatment, the prognosis is quite good. However, the condition may become chronic; a poor outcome may be more likely if the diagnosis and treatment are delayed. Piriformis syndrome may be the most common cause of sciatic-type back pain you've never heard of; or it may be rare, no one is really sure.
Injuries that can cause the syndrome include:
Piriformis syndrome is a condition in which the piriformis muscle, located in the buttock region, spasms and causes buttock pain. The piriformis muscle also can irritate the nearby sciatic nerve and cause pain, numbness and tingling along the back of the leg and into the foot (similar to sciatic pain).
ICD-10-CM Diagnosis Code M62.838.
The piriformis muscle connects the lowermost vertebrae with the upper part of the leg after traveling the "sciatic notch," the opening in the pelvic bone that allows the sciatic nerve to travel into the leg. Here, the muscle and nerve are adjacent and this proximity is why trouble can develop.
The piriformis muscle is a small muscle that begins at the front surface of the sacrum (the V-shaped bone between the buttocks at the base of the spine) and passes through the greater sciatic notch to attach to the top of the thigh bone (femur).
Although there isn't a specific ICD-10-CM code for pain in the buttock, you can use M79. 1 Myalgia.
Answer: An injection of the piriformis muscle is reported CPT® code 20552 Injection(s); single or multiple trigger point(s), 1 or 2 muscle(s) because the injection is into the muscle. CPT® code 64642 Chemodenervation of one extremity; 1-4 muscle(s) is an injection into the nerve.
While both conditions interfere with sciatic nerve function, sciatica results from spinal dysfunction such as a herniated disc or spinal stenosis. Piriformis syndrome, on the other hand, occurs when the piriformis muscle, located deep in the buttock, compresses the sciatic nerve.
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).
Piriformis syndrome is caused by compression of the sciatic nerve as it passes through the buttock. Typically, this occurs from spasm or contracture of the piriformis muscle. When the sciatic nerve is constricted and irritated, the individual will experience the symptoms of piriformis syndrome.
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.
A common cause of piriformis syndrome is tight adductor muscles on the inside of the thigh. This means the abductors on the outside cannot work properly and so put more strain on the piriformis muscle.
external rotator musclePiriformis is a deep external rotator muscle of the hip (hip rotation that turns the toes outwards). It runs from the front of your sacrum and attaches onto the bone you can feel on the outside of your hip (greater trochanter of the femur).
Piriformis syndrome is a neuromuscular disorder that occurs when the sciatic nerve is compressed or otherwise irritated by the piriformis muscle causing pain, tingling and numbness in the buttocks and along the path of the sciatic nerve descending the lower thigh and into the leg.
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code G57.02 and a single ICD9 code, 355.0 is an approximate match for comparison and conversion purposes.
