Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous system
        (T44)

T44.1X3 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by other parasympathomimetics [cholinergics], assault. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Poisoning by other parasympathomimetics, assault

Non-specific codes like T44.1X3 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for poisoning by other parasympathomimetics, assault:

  • Use T44.1X3A for initial encounter - BILLABLE CODE

  • Use T44.1X3D for subsequent encounter - BILLABLE CODE

  • Use T44.1X3S for sequela - BILLABLE CODE

Clinical Information

  • Acetylcholine

    a neurotransmitter found at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system.
  • Acetylcholine Release Inhibitors

    compounds that block release of the neurotransmitter acetylcholine.
  • Acetylcholinesterase

    an enzyme that catalyzes the hydrolysis of acetylcholine to choline and acetate. in the cns, this enzyme plays a role in the function of peripheral neuromuscular junctions. ec 3.1.1.7.
  • Cholinergic Agents

    any drug used for its actions on cholinergic systems. included here are agonists and antagonists, drugs that affect the life cycle of acetylcholine, and drugs that affect the survival of cholinergic neurons. the term cholinergic agents is sometimes still used in the narrower sense of muscarinic agonists, although most modern texts discourage that usage.
  • Cholinergic Agonists

    drugs that bind to and activate cholinergic receptors.
  • Cholinergic Antagonists

    drugs that bind to but do not activate cholinergic receptors, thereby blocking the actions of acetylcholine or cholinergic agonists.
  • Cholinesterase Inhibitors

    drugs that inhibit cholinesterases. the neurotransmitter acetylcholine is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. when cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.
  • Receptors, Cholinergic

    cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.
  • Receptors, Muscarinic

    one of the two major classes of cholinergic receptors. muscarinic receptors were originally defined by their preference for muscarine over nicotine. there are several subtypes (usually m1, m2, m3....) that are characterized by their cellular actions, pharmacology, and molecular biology.
  • Receptors, Nicotinic

    one of the two major classes of cholinergic receptors. nicotinic receptors were originally distinguished by their preference for nicotine over muscarine. they are generally divided into muscle-type and neuronal-type (previously ganglionic) based on pharmacology, and subunit composition of the receptors.
  • Vesicular Acetylcholine Transport Proteins

    vesicular amine transporter proteins that transport the neurotransmitter acetylcholine into small secretory vesicles. proteins of this family contain 12 transmembrane domains and exchange vesicular protons for cytoplasmic acetylcholine.
  • Arecoline

    an alkaloid obtained from the betel nut (areca catechu), fruit of a palm tree. it is an agonist at both muscarinic and nicotinic acetylcholine receptors. it is used in the form of various salts as a ganglionic stimulant, a parasympathomimetic, and a vermifuge, especially in veterinary practice. it has been used as a euphoriant in the pacific islands.
  • Bethanechol

    a slowly hydrolyzing muscarinic agonist with no nicotinic effects. bethanechol is generally used to increase smooth muscle tone, as in the gi tract following abdominal surgery or in urinary retention in the absence of obstruction. it may cause hypotension, heart rate changes, and bronchial spasm.
  • Bethanechol Compounds

    quaternary ammonium compounds that include bethanechol.
  • Carbachol

    a slowly hydrolyzed cholinergic agonist that acts at both muscarinic receptors and nicotinic receptors.
  • Pilocarpine

    a slowly hydrolyzed muscarinic agonist with no nicotinic effects. pilocarpine is used as a miotic and in the treatment of glaucoma.

Coding Guidelines

When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous system (T44). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Table of Drugs and Chemicals

The code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Patient Education


Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:

  • Prescription or over-the-counter medicines taken in doses that are too high
  • Overdoses of illegal drugs
  • Carbon monoxide from gas appliances
  • Household products, such as laundry powder or furniture polish
  • Pesticides
  • Indoor or outdoor plants
  • Metals such as lead and mercury

The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.
