M99.7: Connective tissue and disc stenosis of intervertebral foramina

Connective tissue and disc stenosis of intervertebral foramina, commonly referred to as M99.7, is a specific medical condition that affects the spine. In essence, it represents a narrowing of the openings (foramina) through which nerve roots pass from the spinal cord to other parts of the body. This happens due to a degenerative process that involves the connective tissue and discs between the vertebrae. Over time, these structures may undergo changes that cause them to encroach on these vital passages. This can create pressure or impingement on the nerve roots resulting in a variety of symptoms, primarily pain that can radiate along the course of the affected nerve. Other symptoms can include numbness or tingling sensation, and in severe cases, muscle weakness. This condition often progresses slowly and is typically associated with aging, but can be accelerated due to factors like injury or genetic predisposition.
