T50 — Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances
Not billable
Is T50 billable?
No — T50 is a non-billable header code. T50 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath T50.

Excludes1 — never code together — inherited from T36-T50
The conditions below can never be reported together with T50 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
The underlying condition below must be sequenced before T50. T50 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside T50 to fully describe the condition. T50 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T36-T50
Report an additional code alongside T50 to fully describe the condition. T50 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T50, but a patient may have both at the same time. When documentation supports it, T50 and the excluded code may both be reported.
Excludes2 — not included here — inherited from T36-T50
The conditions below are not part of T50, but a patient may have both at the same time. When documentation supports it, T50 and the excluded code may both be reported.

How long has T50 existed?
T50 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
