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 agents primarily affecting the cardiovascular system
        (T46)

T46.7X3S is a billable diagnosis code used to specify a medical diagnosis of poisoning by peripheral vasodilators, assault, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T46.7X3S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like poisoning by peripheral vasodilators assault. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Clinical Classification

Clinical Information

  • Alprostadil

    a potent vasodilator agent that increases peripheral blood flow.
  • Bencyclane

    a vasodilator agent found to be effective in a variety of peripheral circulation disorders. it has various other potentially useful pharmacological effects. its mechanism may involve block of calcium channels.
  • Betahistine

    a histamine analog and h1 receptor agonist that serves as a vasodilator. it is used in meniere disease and in vascular headaches but may exacerbate bronchial asthma and peptic ulcers.
  • Cyclandelate

    a direct-acting smooth muscle relaxant used to dilate blood vessels.
  • Dihydroergocornine

    a 9,10alpha-dihydro derivative of ergotamine that contains isopropyl sidechains at the 2' and 5' positions of the molecule.
  • Dihydroergotoxine

    a mixture of three different hydrogenated derivatives of ergotamine: dihydroergocornine; dihydroergocristine; and dihydroergocryptine. dihydroergotoxine has been proposed to be a neuroprotective agent and a nootropic agent. the mechanism of its therapeutic actions is not clear, but it can act as an alpha-adrenergic antagonist and a dopamine agonist. the methanesulfonate salts of this mixture of alkaloids are called ergoloid mesylates.
  • Ergoloid Mesylates

    a mixture of the mesylates (methane sulfonates) of dihydroergocornine; dihydroergocristine; and the alpha- and beta-isomers of dihydroergocryptine. the substance produces a generalized peripheral vasodilation and a fall in arterial pressure and has been used to treat symptoms of mild to moderate impairment of mental function in the elderly.
  • Flunarizine

    flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine h1 blocking activity. it is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.
  • Iloprost

    an eicosanoid, derived from the cyclooxygenase pathway of arachidonic acid metabolism. it is a stable and synthetic analog of epoprostenol, but with a longer half-life than the parent compound. its actions are similar to prostacyclin. iloprost produces vasodilation and inhibits platelet aggregation.
  • Isoxsuprine

    a beta-adrenergic agonist that causes direct relaxation of uterine and vascular smooth muscle. its vasodilating actions are greater on the arteries supplying skeletal muscle than on those supplying skin. it is used in the treatment of peripheral vascular disease and in premature labor.
  • Minoxidil

    a potent direct-acting peripheral vasodilator (vasodilator agents) that reduces peripheral resistance and produces a fall in blood pressure. (from martindale, the extra pharmacopoeia, 30th ed, p371)
  • Moxisylyte

    an alpha-adrenergic blocking agent that is used in raynaud's disease. it is also used locally in the eye to reverse the mydriasis caused by phenylephrine and other sympathomimetic agents. (from martindale, the extra pharmacopoeia, 30th ed, p1312)
  • Niacin

    a water-soluble vitamin of the b complex occurring in various animal and plant tissues. it is required by the body for the formation of coenzymes nad and nadp. it has pellagra-curative, vasodilating, and antilipemic properties.
  • Niacinamide

    an important compound functioning as a component of the coenzyme nad. its primary significance is in the prevention and/or cure of blacktongue and pellagra. most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.
  • Xanthinol Niacinate

    a vasodilator used in peripheral vascular disorders and insufficiency. it may cause gastric discomfort and hypotension.
  • Nicergoline

    an ergot derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. it may ameliorate cognitive deficits in cerebrovascular disorders.
  • Nicotinyl Alcohol

    alcohol analog of nicotinic acid which is a direct-acting peripheral vasodilator that causes flushing and may decrease blood pressure. it is used in vasospasm and threatened gangrene.
  • Nylidrin

    a beta-adrenergic agonist. nylidrin causes peripheral vasodilation, a positive inotropic effect, and increased gastric volume of gastric juice. it is used in the treatment of peripheral vascular disorders and premature labor.
  • Pentoxifylline

    a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. it improves blood flow by increasing erythrocyte and leukocyte flexibility. it also inhibits platelet aggregation. pentoxifylline modulates immunologic activity by stimulating cytokine production.
  • Phenoxybenzamine

    an alpha-adrenergic antagonist with long duration of action. it has been used to treat hypertension and as a peripheral vasodilator.
  • Phentolamine

    a nonselective alpha-adrenergic antagonist. it is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of raynaud disease and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.
  • Suloctidil

    a peripheral vasodilator that was formerly used in the management of peripheral and cerebral vascular disorders. it is hepatotoxic and fatalities have occurred. (from martindale, the extra pharmacopoeia, 30th ed, p1312)
  • Tadalafil

    a carboline derivative and phosphodiesterase 5 inhibitor that is used primarily to treat erectile dysfunction; benign prostatic hyperplasia and primary pulmonary hypertension.
  • Tolazoline

    a vasodilator that apparently has direct actions on blood vessels and also increases cardiac output. tolazoline can interact to some degree with histamine, adrenergic, and cholinergic receptors, but the mechanisms of its therapeutic effects are not clear. it is used in treatment of persistent pulmonary hypertension of the newborn.
  • Trimetazidine

    a vasodilator used in angina of effort or ischemic heart disease.

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 agents primarily affecting the cardiovascular system (T46). Use the following options for the aplicable episode of care:

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

Present on Admission (POA)

T46.7X3S is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Convert T46.7X3S to ICD-9-CM

  • ICD-9-CM Code: 909.0 - Late eff drug poisoning
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
  • ICD-9-CM Code: E969 - Late effect assault
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

Table of Drugs and Chemicals

The parent code T46.7X3 of the current diagnosis 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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
