M99.3: Osseous stenosis of neural canal

Osseous stenosis of the neural canal, identified by the ICD-10 code M99.3, is a medical condition characterized by a narrowing of the openings in the spine where the spinal nerves exit, often as a result of bone tissue overgrowth. This can restrict the amount of space available for the nerves running through the spinal canal, potentially causing discomfort or impingement. This condition can be brought on by age-related changes, osteoarthritis, or conditions involving bone overgrowth. Although it isn't always the case, symptoms can include pain, numbness, or weakness in various parts of the body depending on the location of the stenosis in the spine. Over time, these symptoms may become more severe or frequent. A common location for this condition is in the lower back and neck, but it can occur in any part of the spine. The condition may progress slowly (over years) or may remain stable without progression. This narrowing does not always need treatment but can become severe enough to warrant medical intervention.
