The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra. Like the other lumbar vertebrae, L1 has a large, roughly cylindrical region of bone known as the body, or centrum, which makes up most of its mass.
Traumatic L1 Vertebral Body Fracture
What is the L1 Vertebra? What Are the Symptoms of an L1 Injury? The L1 vertebra is the topmost section of the lumbar spinal column. This section of the spine contains a portion of the spinal cord. Injuries to the L1 spine can affect hip flexion, cause paraplegia, loss of bowel/bladder control, and/or numbness in the legs. What is the L2 Vertebra?
The L1 vertebra is level with the ninth rib and the connection between the stomach and the small intestine. Flexion and extension in the L1 vertebrae averages about 10 to 12 degrees.
ICD-10-CM Code for Wedge compression fracture of first lumbar vertebra, initial encounter for closed fracture S32. 010A.
000A for Wedge compression fracture of unspecified thoracic vertebra, initial encounter for closed fracture is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes .
A T12 or L1 compression fracture most commonly happens as a wedge fracture, which occurs when the front part of the vertebra collapses and the back doesn't, making the bone look like a wedge. Osteoporosis, which causes decreased bone density, is a common risk factor for compression fractures.
Vertebral compression fractures (VCFs) occur when the bony block or vertebral body in the spine collapses, which can lead to severe pain, deformity and loss of height. These fractures more commonly occur in the thoracic spine (the middle portion of the spine), especially in the lower part.
Compression fractures may be considered traumatic or pathologic. Review the medical record to determine whether there was significant trauma to cause the compression fracture. If the documentation is unclear, ask the physician for clarification.
The most common type of compression fracture is a wedge fracture, in which the front of the vertebral body collapses but the back does not, meaning that the bone assumes a wedge shape. Sometimes, more than one vertebra fractures, a condition called multiple compression fractures.
lumbar vertebraThe L1 vertebra is the first (topmost) lumbar vertebra. It supports the weight of your upper body, and is a transitional vertebra between the thoracic and lumbar region.
Compression fractures of the spine usually occur at the bottom part of the thoracic spine (T11 and T12) and the first vertebra of the lumbar spine (L1). Compression fractures of the spine generally occur from too much pressure on the vertebral body.
lumbar spineThe lumbar spine makes up the the lower end of the spinal column. It consists of 5 lumbar vertebra that are numbered 1 through 5 from top to bottom i.e. L1, L2, L3, L4, and L5. The L5 vertebra is connected to the top of the sacrum (named the S1 segment) through an intervertebral disc.
This type of vertebral fracture causes loss of body height and a humped back (kyphosis), especially in elderly women. Compression fractures due to trauma can come from a fall, a forceful jump, a car accident, or any event that stresses the spine past its breaking point.
The type of fracture in the spine that is typically caused by osteoporosis is generally referred to as a compression fracture. A compression fracture is usually defined as a vertebral bone in the spine that has decreased at least 15 to 20% in height due to fracture.
The spinal cord ends between the first and second lumbar vertebrae (L1-L2). Below this level, the remaining nerves form the cauda equina, a bundle of nerves resembling a horse's tail.
Though it is not specifically mentioned, “thoracolumbar” likely only includes T12-L1, and “lumbosacral” probably only refers to the L5-S1 interspace. There is a strange rule for cervical disc disorders indicating that you should code to the most superior level of the disorder.
Myelopathy means that there is some sort of neurologic deficit to the spinal cord, whereas radiculopathy means that there is a deficit to nerve roots. Don’t code radiculitis (M54.1-) separately if you use thefourth character of “1” with radiculopathy for the disc disorders (M50.1- or M51.1-). It is already included in the code.
It is already included in the code. Likewise, don’t code sciatica (M54.3-) if you code for lumbar disc with radiculopathy. It would be redundant. On a side note, lumbar radiculopathy (M54.16) might be used if pain is not yet known to be due a disc, but it radiates from the lumbar spine.
