The M43.16 is an ICD-10 code included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) used to designate spondylolisthesis in the lumbar region. Spondylolisthesis is a type of musculoskeletal system problem, specifically a spinal condition that causes the patient to feel pain in their lower back. It can stem from bone or connective tissue disorders.

If a patient suffers from spondylolisthesis, a vertebra (in the lumbar spine, cervical spine, etc.) has slipped out of place (forward displacement) and is now over another vertebra. Patients who experience pain while bending over, numbness or tingling in their feet, and/or have difficulty standing or walking for long periods are symptomatic of Spondylolisthesis.

M43.16 clinical information

If a patient has lower back pain, ask them to be more specific about it. Do they feel that their lower back is stiff? Do they have difficulty walking or standing for long periods? Do they have spasms in their hamstrings? Are their feet numb or weak? Do they feel pain whenever they bend over?

These are symptoms of spondylolisthesis, specifically in the lumbar region. It means that a lumbar vertebra slipped, got displaced forward, and is now over another lumbar vertebra. It can even be that a lumbar vertebra is over a sacral vertebra. This particular condition is commonly caused by overextending the spine. Sometimes, age has to do with it. Wear and tear of the spine and disks can also result in this problem.

To confirm the problem, it's best to conduct a physical examination and an imaging test like an CT or MRI scan.

The treatment will vary depending on the severity of the spondylolisthesis. It's best to try noninvasive treatments like resting, using braces, or doing physical therapy exercises. Medicines and even steroid injections can be used. If none of these work and the pain is severe, surgery might be the only way to fix the problem.
