ICD-10 code M46. 1 for Sacroiliitis, not elsewhere classified is a medical classification as listed by WHO under the range - Dorsopathies .
Sacroiliitis, not elsewhere classified M46. 1 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 M46. 1 became effective on October 1, 2021.
Sacroiliitis (say-kroe-il-e-I-tis) is an inflammation of one or both of your sacroiliac joints — situated where your lower spine and pelvis connect. Sacroiliitis can cause pain in your buttocks or lower back, and can extend down one or both legs. Prolonged standing or stair climbing can worsen the pain.
The sacroiliac joints link your pelvis and lower spine. They're made up of the sacrum — the bony structure above your tailbone and below your lower vertebrae — and the top part (ilium) of your pelvis. There are sacroiliac joints in both the right and left sides of your lower back.
The 2022 edition of ICD-10-CM M46. 98 became effective on October 1, 2021. This is the American ICD-10-CM version of M46.
What causes sacroiliitis? Inflammation of the sacroiliac joint causes most of the symptoms of sacroiliitis. Many medical conditions cause inflammation in the sacroiliac joint, including: Osteoarthritis -This type of wear-and-tear arthritis can occur in the sacroiliac joints and results from the breakdown of ligaments.
Sacroiliac joint dysfunction affects the sciatic nerve and has similar symptoms to sciatica. However, pain along the sciatic nerve caused by sacroiliac joint dysfunction is not caused by a compressed nerve root as it exits the spine, as occurs with true sciatica.
Sacroiliitis Causes Degenerative arthritis, or osteoarthritis of the spine, causing degeneration of the sacroiliac joints and in turn leading to inflammation and SI joint pain. A trauma that affects the lower back, hip or buttocks, such as a car accident or fall.
Imaging tests An X-ray of your pelvis can reveal signs of damage to the sacroiliac joint. If ankylosing spondylitis is suspected, your doctor might recommend an MRI — a test that uses radio waves and a strong magnetic field to produce very detailed cross-sectional images of both bone and soft tissues.
Anatomy of the Sacroiliac Joint The sacroiliac joint connects the hip bones (iliac crests) to the sacrum, the triangular bone between the lumbar spine and the tailbone (coccyx).
The SI joints are located on either side of the sacral spine and are situated deep in the pelvis. Each SI joint is secured and well protected by strong ligaments. The joint surface extends from the S1 spinal segment to the middle of the S3 spinal segment.
The sacroiliac joint is a large joint in your lower back and buttocks region.
