The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on balloon catheter dilation of paranasal sinus ostia for chronic sinusitis.


Sinusitis occurs when air-filled cavities of the face (the sinuses) become inflamed. Balloon catheter dilation aims to help keep the sinus passages open and unobstructed by gently inflating a small balloon, which is introduced through the nose via a flexible tube.

Coding recommendations

Depending on which sinus the procedure is performed on one of the following OPCS-4 codes is assigned:

E13.8 Other specified other operations on maxillary antrum

E14.8 Other specified operations on frontal sinus

E15.8 Other specified operations on sphenoid sinus

E17.8 Other specified operations on unspecified nasal sinus

The following three codes are assigned directly after one of the codes listed above:

Y76.1 Functional endoscopic sinus surgery

Y40.3 Balloon dilation of organ NOC

Y53.4 Approach to organ under fluoroscopic control 

In addition an ICD-10 code from category J32.- Chronic sinusitis is assigned
