- Code Navigator:
T46.6X6 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of underdosing of antihyperlipidemic and antiarteriosclerotic drugs. 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 Underdosing of antihyperlipidemic and antiarterio drugs
Non-specific codes like T46.6X6 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 underdosing of antihyperlipidemic and antiarterio drugs:
Clinical Information
Bezafibrate
an antilipemic agent that lowers cholesterol and triglycerides. it decreases low density lipoproteins and increases high density lipoproteins.Clofibrate
a fibric acid derivative used in the treatment of hyperlipoproteinemia type iii and severe hypertriglyceridemia. (from martindale, the extra pharmacopoeia, 30th ed, p986)Colestipol
highly crosslinked and insoluble basic anion exchange resin used as anticholesteremic. it may also may reduce triglyceride levels.Fenofibrate
an antilipemic agent which reduces both cholesterol and triglycerides in the blood.Gemfibrozil
a lipid-regulating agent that lowers elevated serum lipids primarily by decreasing serum triglycerides with a variable reduction in total cholesterol.Halofenate
an antihyperlipoproteinemic agent and uricosuric agent.Linoleic Acid
a doubly unsaturated fatty acid, occurring widely in plant glycosides. it is an essential fatty acid in mammalian nutrition and is used in the biosynthesis of prostaglandins and cell membranes. (from stedman, 26th ed)Linoleic Acids
eighteen-carbon essential fatty acids that contain two double bonds.Linoleic Acids, Conjugated
a collective term for a group of around nine geometric and positional isomers of linoleic acid in which the trans/cis double bonds are conjugated, where double bonds alternate with single bonds.Linoleoyl-CoA Desaturase
an enzyme that catalyzes the syn-dehydrogenation of linoleol-coa gamma-linolenoyl-coa. it was formerly characterized as ec 1.14.99.25.Lovastatin
a fungal metabolite isolated from cultures of aspergillus terreus. the compound is a potent anticholesteremic agent. it inhibits 3-hydroxy-3-methylglutaryl coenzyme a reductase (hydroxymethylglutaryl coa reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. it also stimulates the production of low-density lipoprotein receptors in the liver.Oleic Acid
an unsaturated fatty acid that is the most widely distributed and abundant fatty acid in nature. it is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. (stedman, 26th ed)Oleic Acids
a group of fatty acids that contain 18 carbon atoms and a double bond at the omega 9 carbon.Ricinoleic Acids
eighteen carbon fatty acids that comprise the great majority of castor oil, which is from the seed of ricinus.Pravastatin
an antilipemic fungal metabolite isolated from cultures of nocardia autotrophica. it acts as a competitive inhibitor of hmg coa reductase (hydroxymethylglutaryl coa reductases).Probucol
a drug used to lower ldl and hdl cholesterol yet has little effect on serum-triglyceride or vldl cholesterol. (from martindale, the extra pharmacopoeia, 30th ed, p993).Safflower Oil
an oily liquid extracted from the seeds of the safflower, carthamus tinctorius. it is used as a dietary supplement in the management of hypercholesterolemia. it is used also in cooking, as a salad oil, and as a vehicle for medicines, paints, varnishes, etc. (dorland, 28th ed & random house unabridged dictionary, 2d ed)Simvastatin
a derivative of lovastatin and potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme a reductase (hydroxymethylglutaryl coa reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. it may also interfere with steroid hormone production. due to the induction of hepatic ldl receptors, it increases breakdown of ldl cholesterol.Sitosterols
a family of sterols commonly found in plants and plant oils. alpha-, beta-, and gamma-isomers have been characterized.Triparanol
antilipemic agent with high ophthalmic toxicity. according to merck index, 11th ed, the compound was withdrawn from the market in 1962 because of its association with the formation of irreversible cataracts.
Coding Guidelines
Underdosing refers to taking less of a medication than is prescribed by a provider or a manufacturer's instruction. Codes for underdosing should never be assigned as principal or first-listed codes. If a patient has a relapse or exacerbation of the medical condition for which the drug is prescribed because of the reduction in dose, then the medical condition itself should be coded.
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
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
Medication Errors
Medicines treat infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the health care provider's office, at the pharmacy, or at home. You can help prevent errors by:
- Knowing your medicines. When you get a prescription, ask the name of the medicine and check to make sure that the pharmacy gave you the right medicine. Make sure that you understand how often you should take the medicine and how long you should take it.
- Keeping a list of medicines.
- Write down all of the medicines that you are taking, including the names of your medicines, how much you take, and when you take them. Make sure to include any over-the-counter medicines, vitamins, supplements, and herbs that you take.
- List the medicines that you are allergic to or that have caused you problems in the past.
- Take this list with you every time you see a health care provider.
- Reading medicine labels and following the directions. Don't just rely on your memory - read the medication label every time. Be especially careful when giving medicines to children.
- Asking questions. If you don't know the answers to these questions, ask your health care provider or pharmacist:
- Why am I taking this medicine?
- What are the common side effects?
- What should I do if I have side effects?
- When should I stop this medicine?
- Can I take this medicine with the other medicines and supplements on my list?
- Do I need to avoid certain foods or alcohol while taking this medicine?
