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).
