M99.65
Osseous and subluxation stenosis of intervertebral foramina of pelvic region
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code M99.65 refers to a condition characterized by narrowing (stenosis) in the openings (foramina) through which nerves exit the spinal canal in the pelvic region. This narrowing can be caused by bony growths or vertebral subluxation—a partial dislocation of the vertebrae. Such conditions may lead to nerve compression, which can result in discomfort and neurological symptoms in the pelvis and lower limbs. Recognizing this condition is essential for healthcare providers to manage symptoms effectively and prevent potential complications.
Causes & Symptoms
Clinical Causes: Degenerative changes in the spine, such as osteoarthritis or arthritis of the facet joints Formation of bony growths (osteophytes) due to aging or degenerative processes Previous spinal injuries leading to abnormal vertebral alignment or subluxation Congenital spinal abnormalities that predispose to foraminal narrowing Trauma causing vertebral subluxation or fracture resulting in foraminal stenosis Degeneration of intervertebral discs contributing to structural changes in the spinal canal Involvement of inflammatory or infectious processes affecting spinal stability
Key Symptoms: Localized pain in the pelvic or lower back region Radicular pain radiating to the buttocks, thighs, or legs Numbness or tingling sensations in the affected lower limbs Weakness in leg muscles due to nerve compression Difficulty walking or maintaining balance Muscle cramps or spasms in the pelvic area Sensory disturbances, such as a burning sensation or loss of sensation
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination focusing on neurological function Imaging studies such as MRI or CT scans to visualize nerve impingement and bony structures X-rays to assess vertebral alignment and detect osseous changes Electromyography (EMG) and nerve conduction studies to evaluate nerve function
Treatment Protocols: Conservative management including physical therapy to improve spinal stability and reduce nerve pressure Pain management with medications such as NSAIDs or topical analgesics Epidural steroid injections to reduce inflammation and alleviate symptoms Lifestyle modifications like weight management and activity adjustments Surgical interventions, such as foraminotomy or decompression surgery, in cases of persistent or severe symptoms

Documentation
How do I report M99.65?
