T50.912D — Poisoning by multiple unspecified drugs, medicaments and biological substances, intentional self-harm, subsequent encounter
Is T50.912D billable?
Yes, but T50.912D is an unspecified code. T50.912D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T50.912D is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting T50.912D.

Excludes1 — never code together — inherited from T36-T50
The conditions below can never be reported together with T50.912D on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- toxic reaction to local anesthesia in pregnancy (O29.3-)
Code first — inherited from T36-T50
