M51.17  – Intervertebral disc disorders with radiculopathy, lumbosacral region

The M51.17 is an ICD code included in the International Classification of Diseases, Tenth Revision, Clinical Modification (or the ICD-10-CM for short), and it is used to designate intervertebral disc disorders with radiculopathy, lumbosacral region.

An intervertebral disc disorder can indicate the degeneration of the lumbar disc or its herniation or bulging. This is not good because it limits a person's movement, makes their lower back feel weak, and can even cause pain and numbness. On the other hand, radiculopathy is a type of pain that results from nerve root compression and irritation. In the context of this ICD code, these problems are located in the lumbosacral region of the back.

Is the M51.17 billable?

Yes, the M51.17 ICD code is billable. Medicare and Medicaid services and all healthcare providers covered by the Health Insurance Portability and Accountability Act (HIPAA) use ICD-10 codes for diagnoses and inpatient procedures.

M51.17 clinical information

Around the age of 40, most people begin to develop disc degeneration, mainly because of wear and tear. When this happens, the discs won't be able to do their job as shock absorbers as well as they used to, and eventually, they will wear to the point that our bones will start rubbing against each other. That's not good because that will cause pain and give rise to intervertebral disc disorders like herniated discs, scoliosis, and even spinal stenosis.

These disorders can add to the pain and even compress or irritate nerve roots. If nerve roots are affected, this can cause radiculopathy, a radiating pain that can spread to the legs.

In the context of this ICD code, the disc disorder and the radiculopathy are in the lumbosacral region of the back.

If a patient mentions any of the following symptoms, then there is a chance that they might have an intervertebral disc disorder with radiculopathy:

  • Sharp pain in the lumbosacral region
  • If they feel pain whenever they try to lift objects, especially heavy ones
  • If they have a hard time moving and twisting their back, plus feel pain while moving
  • Radiating pain in the lumbosacral region that reaches the legs
  • Weakness
  • Tingling

To find out, you can perform physical examination techniques that gauge the lower back and imaging tests.

These problems are normally treated using pain medication, anti-inflammation medication, physical therapy, the use of back braces, and even acupuncture. For severe cases, surgery might be the best bet.

Commonly asked questions

Yes, M51.17 (intervertebral disc disorders with radiculopathy, lumbosacral region) is a billable ICD-10-CM code used for reimbursement purposes.

M51.16 refers to intervertebral disc disorders with radiculopathy in the lumbar region. It describes a condition in which a damaged or herniated disc in the lumbar spine causes nerve root compression, leading to pain, numbness, or weakness in the lower back and legs.

Lumbosacral disc disorders with radiculopathy are typically managed with pain medication, physical therapy, and steroid injections, while surgery is considered for severe, persistent cases.
