M46.3Infection of intervertebral disc (pyogenic)

M46.3 is the ICD-10-CM diagnosis code for infection of intervertebral disc (pyogenic). It belongs to category M46 (other inflammatory spondylopathies), block M45-M49 (spondylopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

Within M46 (other inflammatory spondylopathies), M46.3 is specifically for infection of intervertebral disc (pyogenic). Related codes cover spinal enthesopathy (M46.0), Sacroiliitis, not elsewhere classified (M46.1), osteomyelitis of vertebra (M46.2), Discitis, unspecified (M46.4), other infective spondylopathies (M46.5), other specified inflammatory spondylopathies (M46.8) and unspecified inflammatory spondylopathy (M46.9).

To report this condition, pick the subcode that matches the documentation: M46.30 (site unspecified), M46.31 (occipito-atlanto-axial region), M46.32 (cervical region), M46.33 (cervicothoracic region), M46.34 (thoracic region), M46.35 (thoracolumbar region), M46.36 (lumbar region), M46.37 (lumbosacral region) and 2 more.

Use an additional code (B95-B97) to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
