0.000What This Code Means
A bacterial infection of the intervertebral discs (the cushions between vertebrae) when the specific location in the spine is not documented.
Coding Tips
- •Use this code only when the anatomical site is truly unspecified; always attempt to obtain specific location documentation
- •If the site becomes known during the episode of care, update the code to the more specific regional variant
Clinical Significance
Pyogenic intervertebral disc infections represent serious spinal infections requiring aggressive antibiotic therapy and monitoring for neurological complications. These infections can rapidly progress to vertebral osteomyelitis or epidural abscess if untreated.
Documentation Requirements
- ✓Confirmation of pyogenic (bacterial) etiology
- ✓Imaging evidence of disc space infection
- ✓Blood cultures or tissue biopsy results when available
- ✓Associated symptoms (fever, back pain, neurological deficits)
- ✓Duration and progression of infection
- ✓Response to antibiotic therapy
- ✓Any complications such as abscess formation
- ✓Specific site documentation when possible for more precise coding
