About coding medication damage

The ICD-10-CM code for medication damage is T88.7 (Unspecified adverse effect of drug or medicament).

Within T88, choose T88.7 (Unspecified adverse effect of drug or medicament) only when documentation doesn't support a more specific option: infection following immunization (T88.0), other complications following immunization, not elsewhere classified (T88.1), shock due to anesthesia (T88.2), malignant hyperthermia due to anesthesia (T88.3), failed or difficult intubation (T88.4), other complications of anesthesia (T88.5), anaphylactic reaction due to adverse effect of correct drug or medicament properly administered (T88.6), other specified complications of surgical and medical care, not elsewhere classified (T88.8) and 1 more.

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.

Don't report T88.7 together with the conditions in its Excludes1 note: specified adverse effects of drugs and medicaments (A00-R94 and T80-T88.6, T88.8).

Don't confuse with (Excludes1 for T88.7)
