Infection of intervertebral disc (pyogenic), site unsp

This code signifies an infection of the intervertebral disc, specifically of a pyogenic (pus-forming) nature, when the exact location along the spine is not specified in the medical record. It represents a bacterial or other microbial infection affecting the disc space, leading to inflammation and potential destruction of the disc.

Use this code when documentation clearly indicates a pyogenic intervertebral disc infection but does not specify the cervical, thoracic, lumbar, or lumbosacral region. This often occurs in initial diagnostic phases or when the infection is widespread without a clear primary site. Supporting documentation includes imaging reports (MRI, CT) showing disc space infection, positive cultures from disc aspiration, and clinical signs of infection.

• Do not use this code if the specific spinal region (e.g., cervical, thoracic, lumbar) is documented; instead, select a more specific M46.3- subcategory.
• Consider an additional code to identify the infectious organism (e.g., B95-B97) if known.
• Ensure documentation differentiates pyogenic infection from other forms of discitis (e.g., nonpyogenic, tuberculous) to avoid miscoding.
