About coding sinus barotrauma
The ICD-10-CM code for sinus barotrauma is T70.1 (Sinus barotrauma).
Within T70 (effects of air pressure and water pressure), T70.1 is specifically for sinus barotrauma. Related codes cover otitic barotrauma (T70.0), other and unspecified effects of high altitude (T70.2), Caisson disease [decompression sickness] (T70.3), effects of high-pressure fluids (T70.4), other effects of air pressure and water pressure (T70.8) and effect of air pressure and water pressure, unspecified (T70.9).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
