Cervical disc disorder w radiculopathy, cervicothor region

This code signifies a degenerative or structural abnormality of an intervertebral disc in the cervicothoracic region (C7-T1) that is causing nerve root compression. This compression typically results in symptoms such as pain, numbness, tingling, or weakness radiating into the upper extremities or trunk.

Use this code when documentation clearly indicates a cervical disc disorder affecting the C7-T1 level, accompanied by radicular symptoms. This diagnosis is supported by findings from physical examination (e.g., dermatomal sensory deficits, myotomal weakness), imaging studies (e.g., MRI showing disc herniation or bulging at C7-T1 impinging on a nerve root), and electrodiagnostic studies (e.g., EMG/NCS confirming radiculopathy).

• Ensure the documentation specifies the cervicothoracic region (C7-T1) for accurate coding.
• Distinguish from cervical disc disorders without radiculopathy (M50.2-) or those affecting other cervical regions.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
