M99.6
Osseous and subluxation stenosis of intervertebral foramina
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code M99.6 refers to a condition characterized by narrowing (stenosis) of the openings (foramina) through which nerves exit the spine. This narrowing is caused by bone changes (osseous stenosis) or partial dislocation (subluxation) of the vertebrae. Such conditions can put pressure on spinal nerves, leading to discomfort and neurological symptoms. Understanding this condition can help patients recognize symptoms and seek appropriate medical evaluation.
Causes & Symptoms
Clinical Causes: Degenerative disc disease Osteoarthritis leading to bone spurs Spinal injuries causing vertebral subluxation Congenital spinal canal narrowing Previous spinal surgeries resulting in scar tissue or misalignment Trauma or injury affecting spinal stability Infections or tumors that cause bone changes
Key Symptoms: Localized back pain that may radiate to limbs Numbness or tingling sensations in affected areas Weakness in muscles served by affected nerves Difficulty walking or maintaining balance Loss of reflexes in certain areas Muscle cramps or spasms near the spine Sensory changes such as tingling or burning sensations
Diagnostic & Treatment
Diagnosis Path: Magnetic Resonance Imaging (MRI) to visualize nerve compression and soft tissue structures Computed Tomography (CT) scan for detailed imaging of bone structures X-rays to assess vertebral alignment and bone spurs Electromyography (EMG) to evaluate nerve and muscle function Physical neurological examination to assess reflexes, strength, and sensory function
Treatment Protocols: Conservative measures such as physical therapy to strengthen surrounding muscles and improve spinal stability Medications including pain relievers, anti-inflammatory drugs, or nerve pain medications Epidural steroid injections to reduce inflammation and nerve swelling Lifestyle modifications like weight management and activity adjustments to alleviate stress on the spine Bracing in certain cases to stabilize the spine Surgical interventions such as decompression procedures or spinal fusion when conservative treatments are ineffective
Clinical Advice & FAQs

Yes, M99.6 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report M99.6?
Clinical documentation must specify the nature of Osseous and subluxation stenosis of intervertebral foramina and any associated comorbidities for accurate reporting.
