About coding injection

The ICD-10-CM code for injection is T70.4 (Effects of high-pressure fluids).

Within T70 (effects of air pressure and water pressure), T70.4 is specifically for effects of high-pressure fluids. Related codes cover otitic barotrauma (T70.0), sinus barotrauma (T70.1), other and unspecified effects of high altitude (T70.2), Caisson disease [decompression sickness] (T70.3), 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.
