Concussion and edema of cervical spinal cord, sequela

This code signifies the long-term or late effects resulting from a concussion and associated edema of the cervical spinal cord. It indicates a residual condition or complication that persists after the acute phase of the initial injury has resolved. This could include chronic pain, neurological deficits, or functional limitations directly attributable to the past cervical spinal cord trauma.

Apply this code when documenting a patient presenting with persistent symptoms or conditions that are a direct consequence of a previously sustained concussion and edema of the cervical spinal cord. Documentation should clearly link the current sequela to the past injury, often through a history of the acute event and ongoing clinical assessment. This code is appropriate for follow-up visits addressing these chronic issues.

• Always sequence this sequela code first, followed by codes for the specific residual conditions or symptoms.
• Ensure documentation explicitly states the "sequela" or "late effect" of the cervical spinal cord injury.
• Do not use this code for acute or subacute injuries; those require codes from the initial injury categories.
