- Code Navigator:
T50.0X5A is a billable diagnosis code used to specify a medical diagnosis of adverse effect of mineralocorticoids and their antagonists, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.
T50.0X5A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like adverse effect of mineralocorticoids and their antagonists. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

- Fludrocortisone adverse reaction
- Mineralocorticoid adverse reaction
- Potassium canrenoate adverse reaction
- Potassium sparing diuretic adverse reaction
- Potassium sparing diuretic adverse reaction
- Potassium sparing diuretic adverse reaction
- Spironolactone adverse reaction
Clinical Classification
Clinical Category is Adverse effects of drugs and medicaments, initial encounter
- CCSR Category Code: INJ028
- Inpatient Default CCSR: X - Not applicable.
- Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Clinical Information
Aldosterone
a hormone secreted by the adrenal cortex that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.Cytochrome P-450 CYP11B2
a mitochondrial cytochrome p450 enzyme that catalyzes the 18-hydroxylation of steroids in the presence of molecular oxygen and nadph-specific flavoprotein. this enzyme, encoded by cyp11b2 gene, is important in the conversion of corticosterone to 18-hydroxycorticosterone and the subsequent conversion to aldosterone.Mineralocorticoid Receptor Antagonists
drugs that bind to and block the activation of mineralocorticoid receptors by mineralocorticoids such as aldosterone.Receptors, Mineralocorticoid
cytoplasmic proteins that specifically bind mineralocorticoids and mediate their cellular effects. the receptor with its bound ligand acts in the nucleus to induce transcription of specific segments of dna.Canrenoic Acid
a synthetic pregnadiene derivative with anti-aldosterone activity.Canrenone
a synthetic pregnadiene compound with anti-aldosterone activity.Fludrocortisone
a synthetic mineralocorticoid with anti-inflammatory activity.Spironolactone
a potassium sparing diuretic that acts by antagonism of aldosterone in the distal renal tubules. it is used mainly in the treatment of refractory edema in patients with congestive heart failure, nephrotic syndrome, or hepatic cirrhosis. its effects on the endocrine system are utilized in the treatments of hirsutism and acne but they can lead to adverse effects. (from martindale, the extra pharmacopoeia, 30th ed, p827)
Coding Guidelines
When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.
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
Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:
- Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.
Convert T50.0X5A to ICD-9-CM
- ICD-9-CM Code: 995.29 - Adv eff med/biol NEC/NOS
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: E932.0 - Adv eff corticosteroids
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 T50.0X5 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
Drug Reactions
Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.
What is a drug interaction?
A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:
- Two drugs, such as aspirin and blood thinners
- Drugs and food, such as statins and grapefruit
- Drugs and supplements, such as gingko and blood thinners
- Drugs and medical conditions, such as aspirin and peptic ulcers
Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.
What are side effects?
Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.
What are drug allergies?
Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.
How can I stay safe when taking medicines?
When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.

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.
