Other cervical disc displacement at C4-C5 level

This code signifies a non-traumatic displacement of the intervertebral disc located between the fourth and fifth cervical vertebrae (C4-C5), excluding disc herniation or rupture. This displacement can lead to nerve root compression or myelopathy, manifesting as neck pain, radiculopathy, or neurological deficits.

Use this code when documentation specifies a cervical disc displacement at the C4-C5 level that is not explicitly described as a herniation or rupture. This typically applies to conditions like disc protrusion or bulging without frank herniation. Supporting documentation includes imaging reports (MRI, CT) confirming the displacement and physician notes detailing the location and nature of the disc pathology.

• Differentiate carefully between "displacement," "herniation" (M50.1-), and "degeneration" (M50.3-) at the C4-C5 level.
• Always confirm the specific cervical level (C4-C5) from the physician's documentation or imaging reports.
• If radiculopathy or myelopathy is present due to the displacement, code these manifestations separately and sequence them after the disc displacement code.
