The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on laser-assisted cerebral vascular anastomosis without temporary arterial occlusion.
Arteries in the head may need to be bypassed as part of an operation, usually because of 'ballooning' or blockage of arteries. Laser-assisted cerebral vascular anastomosis without temporary arterial occlusion aims to create a bypass without the need to temporarily interrupt the blood flow to the brain.
One of the following OPCS-4 codes is selected as appropriate:
L29.2 Intracranial bypass to carotid artery NEC
L29.6 High flow interposition extracranial to intracranial bypass from external carotid artery to middle cerebral artery
L29.7 Bypass of carotid artery by anastomosis of superficial temporal artery to middle cerebral artery
L34.2 Anastomosis of cerebral artery
Plus the following code:
Y08.8 Other specified laser therapy to organ NOC
Note: It is not possible to classify ‘without temporary arterial occlusion’ using OPCS-4.
