Hemorrhage due to nervous system prosth dev/grft, subs

This code signifies bleeding that occurs as a complication of a previously implanted nervous system device, such as a deep brain stimulator, spinal cord stimulator, or shunt. The hemorrhage is directly attributable to the presence or malfunction of the prosthetic device, implant, or graft within the nervous system.

Apply this code when a patient presents for follow-up care or treatment of hemorrhage that developed after the initial placement of a nervous system prosthetic device. This includes situations where the bleeding is being managed, investigated further, or treated in a subsequent encounter, not the initial complication encounter.

• Requires a seventh character of 'D' for subsequent encounter, indicating ongoing care for the complication.
• Always code the specific type of nervous system device (e.g., T85.0- for mechanical complication of ventricular intracranial shunt) as a primary or secondary diagnosis if known.
• Ensure documentation clearly links the hemorrhage to the nervous system prosthetic device and specifies the encounter as subsequent.
