About the M50 Code Range
Cervical disc disorders affect discs in the neck. These codes distinguish the type of disorder and its location.
The main divisions separate disorders with myelopathy (M50.0) or radiculopathy (M50.1), disc displacement (M50.2), disc degeneration (M50.3), other disorders (M50.8), and unspecified disorders (M50.9). Each division then distinguishes an unspecified neck region, the high or mid-cervical region, and the region where the neck meets the upper back. Mid-cervical codes separate an unspecified level from the C4-C5, C5-C6, and C6-C7 levels.
