The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Percutaneous tibial nerve stimulation (PTNS) for faecal incontinence.
Faecal incontinence occurs when a person loses (often only partially) voluntary control of their bowel movements, resulting in leakage of faeces. The condition may relate to inadequate formation of the anus from birth. It can also relate to diseases of the nervous system (such as spina bifida, spinal cord injury, multiple sclerosis), pelvic organ prolapse, or previous pelvic surgery or radiotherapy. In women, another cause is injury to the anal canal during childbirth. This procedure involves inserting a fine needle into a nerve just above the ankle and passing a mild electric current through the needle to the nerves that control bowel function
A70.4 Insertion of neurostimulator electrodes into peripheral nerve
Z12.2 Posterior tibial nerve
In addition ICD-10 code R15.X Faecal incontinence is assigned.
