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 diuretics and other and unspecified drugs, medicaments and biological substances
        (T50)

T50.4X4 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 drugs affecting uric acid metabolism, undetermined. 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 drugs affecting uric acid metabolism, undet

Non-specific codes like T50.4X4 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 drugs affecting uric acid metabolism, undet:

  • Use T50.4X4A for initial encounter - BILLABLE CODE

  • Use T50.4X4D for subsequent encounter - BILLABLE CODE

  • Use T50.4X4S for sequela - BILLABLE CODE

Clinical Information

  • Allopurinol

    a xanthine oxidase inhibitor that decreases uric acid production. it also acts as an antimetabolite on some simpler organisms.
  • Benzbromarone

    uricosuric that acts by increasing uric acid clearance. it is used in the treatment of gout.
  • Colchicine

    a major alkaloid from colchicum autumnale l. and found also in other colchicum species. its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial mediterranean fever (periodic disease).
  • Probenecid

    the prototypical uricosuric agent. it inhibits the renal excretion of organic anions and reduces tubular reabsorption of urate. probenecid has also been used to treat patients with renal impairment, and, because it reduces the renal tubular excretion of other drugs, has been used as an adjunct to antibacterial therapy.
  • Sulfinpyrazone

    a uricosuric drug that is used to reduce the serum urate levels in gout therapy. it lacks anti-inflammatory, analgesic, and diuretic properties.
  • Urate Oxidase

    an enzyme that catalyzes the conversion of urate and unidentified products. it is a copper protein. the initial products decompose to form allantoin. ec 1.7.3.3.

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 diuretics and other and unspecified drugs, medicaments and biological substances (T50). 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.
