The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on photodynamic therapy for brain tumours.


Brain tumours may arise from brain tissue or spread from cancers in other parts of the body. Treatment usually consists of an operation to establish the nature of the tumour and, when possible, remove as much of it as seems safe. Photodynamic therapy (often abbreviated to PDT) has been developed as additional therapy (to enhance the effect of surgery) or as a treatment for tumours that are inoperable. It involves giving the patient a drug that makes the tissue sensitive to light. A laser light source is used during the operation and in some cases for a few days afterwards to activate the light-sensitive substance with the aim of destroying the tumour cells.

Coding recommendations

A code from one of the following OPCS-4 categories is selected:

A01.- Major excision of tissue of brain

A02.- Excision of lesion of tissue of brain

A06.- Other excision of lesion of tissue of brain

A38.- Extirpation of lesion of meninges of brain

A43.- Other extirpation of lesion of meninges of brain

A subsidiary code Y13.6 Photodynamic therapy of lesion of organ NOC is also required.

In addition an ICD-10 code from categories C70. - Malignant neoplasm of meninges or C71. - Malignant neoplasm of brain or C79.3 Secondary malignant neoplasm of brain and cerebral meninges is assigned.
