Infection of intvrt disc (pyogenic), lumbosacral region

This code signifies a bacterial infection affecting the intervertebral disc within the lumbar or sacral spine. This condition, often referred to as discitis, involves inflammation and destruction of the disc tissue due to a pyogenic (pus-forming) organism. Patients typically present with severe back pain, fever, and elevated inflammatory markers.

Apply this code when documentation clearly indicates a diagnosis of pyogenic discitis specifically located in the lumbosacral region. This diagnosis is often supported by imaging studies (MRI, CT) showing disc space narrowing, endplate erosion, and fluid collections, along with positive blood cultures or disc biopsy results.

• Ensure the documentation specifies a pyogenic infection; otherwise, a non-pyogenic discitis code may be more appropriate.
• Always code the underlying infectious organism (e.g., Staphylococcus aureus) as an additional diagnosis if identified.
• Differentiate from other spinal infections like osteomyelitis (M46.2-) or spondylodiscitis (M46.4-) if the infection is primarily confined to the disc.
