ICD 10 Code T44.4X4

Poisoning by predominantly alpha-adrenoreceptor agonists, undetermined
“Poisoning by predom alpha-adrenocpt agonists, undetermined” for short

T44.4X4 is a non-billable ICD-10 code for Poisoning by predominantly alpha-adrenoreceptor agonists, undetermined. It should not be used for HIPAA-covered transactions as a more specific code is available to choose from below.

↓ See below for any exclusions, inclusions or special notations

7th Character selection:

The appropriate 7th character is to be added to each code from category T44

See also, ICD-10 Table of Drugs & Chemicals.

Coding structure:

ICD-10 code T44.4X4 is based on the following Tabular structure:

Chapter 19: Injury, poisoning and certain other consequences of external causes
  • Section T36-T50: Poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances
    • Category T44: Poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous system

↑ Parent code:
T44.4X for Poisoning by, adverse effect of and underdosing of predominantly alpha-adrenoreceptor agonists

Should you use T44.4X4 or T444X4 (with or without decimal point)?
DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically.

Section T36-T50 — Poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances

The drug giving rise to the adverse effect should be identified by use of codes from categories T36-T50 with fifth or sixth character 5.

Use additional code(s) to specify:
manifestations of poisoning
underdosing or failure in dosage during medical and surgical care (Y63.6, Y63.8-Y63.9)
underdosing of medication regimen (Z91.12-, Z91.13-)

Code first  , for adverse effects, the nature of the adverse effect, such as:
  adverse effect NOS (T88.7)
  aspirin gastritis (K29.-)
  blood disorders (D56-D76)
  contact dermatitis (L23-L25)
  dermatitis due to substances taken internally (L27.-)
  nephropathy (N14.0-N14.2)

Includes:

  • adverse effect of correct substance properly administered
  • poisoning by overdose of substance
  • poisoning by wrong substance given or taken in error
  • underdosing by (inadvertently) (deliberately) taking less substance than prescribed or instructed

Excludes1
