T44.8X — Poisoning by, adverse effect of and underdosing of centrally-acting and adrenergic- neuron-blocking agents
Is T44.8X billable?
No — T44.8X is a non-billable header code. T44.8X 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 18 billable codes beneath T44.8X.

Excludes1 — never code together — inherited from T36-T50
The conditions below can never be reported together with T44.8X 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 T44.8X. T44.8X describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside T44.8X to fully describe the condition. T44.8X 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 T44.8X to fully describe the condition. T44.8X is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T44.8X, but a patient may have both at the same time. When documentation supports it, T44.8X and the excluded code may both be reported.
Excludes2 — not included here — inherited from T36-T50
The conditions below are not part of T44.8X, but a patient may have both at the same time. When documentation supports it, T44.8X and the excluded code may both be reported.
Excludes2 — not included here — inherited from T44.8
The conditions below are not part of T44.8X, but a patient may have both at the same time. When documentation supports it, T44.8X and the excluded code may both be reported.

How long has T44.8X existed?
T44.8X 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.
