2024 ICD-10-CM Diagnosis Code T44.5X6

Specific Coding Applicable to Underdosing of predominantly beta-adrenoreceptor agonists

Non-specific codes like T44.5X6 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 predominantly beta-adrenoreceptor agonists:

Clinical Information

• Beclomethasone

  an anti-inflammatory, synthetic glucocorticoid. it is used topically as an anti-inflammatory agent and in aerosol form for the treatment of asthma.

• Budesonide

  a glucocorticoid used in the management of asthma, the treatment of various skin disorders, and allergic rhinitis.

• Budesonide, Formoterol Fumarate Drug Combination

  a pharmaceutical preparation of budesonide and formoterol fumarate that is used as an anti-asthmatic agent and for the treatment of chronic obstructive pulmonary disease.

• Dobutamine

  a catecholamine derivative with specificity for beta-1 adrenergic receptors. it is commonly used as a cardiotonic agent after cardiac surgery and during dobutamine stress echocardiography.

• Echocardiography, Stress

  a method of recording heart motion and internal structures by combining ultrasonic imaging with exercise testing (exercise test) or pharmacologic stress.

• Epinephrine

  the active sympathomimetic hormone from the adrenal medulla. it stimulates both the alpha- and beta- adrenergic systems, causes systemic vasoconstriction and gastrointestinal relaxation, stimulates the heart, and dilates bronchi and cerebral vessels. it is used in asthma and cardiac failure and to delay absorption of local anesthetics.

• Racepinephrine

  a racemic mixture of d-epinephrine and l-epinephrine.

• Receptors, Adrenergic

  cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. the two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. adrenergic receptors may also be classified according to the subtypes of g-proteins with which they bind; this scheme does not respect the alpha-beta distinction.

• Isoetharine

  adrenergic beta-2 agonist used as bronchodilator for emphysema, bronchitis and asthma.

• Prenalterol

  a partial adrenergic agonist with functional beta 1-receptor specificity and inotropic effect. it is effective in the treatment of acute cardiac failure, postmyocardial infarction low-output syndrome, shock, and reducing orthostatic hypotension in the shy-rager syndrome.

• Procaterol

  a long-acting beta-2-adrenergic receptor agonist.

• Ritodrine

  an adrenergic beta-2 agonist used to control premature labor.

• Xamoterol

  a phenoxypropanolamine derivative that is a selective beta-1-adrenergic agonist.

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 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

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?
