Hyperkalemia, or elevated potassium levels in the blood, is a medical condition recognized by the ICD-10-CM code E87.5. While primarily used in healthcare settings, understanding diagnosis codes like E87.5 can be valuable for anyone working with data that intersects with medical information. This article provides a comprehensive overview of the E87.5 diagnosis code, its clinical context, and related information.
What is Hyperkalemia?
Hyperkalemia is a condition characterized by a higher-than-normal level of potassium in your blood. Potassium is a vital electrolyte that helps nerves and muscles function properly. Your kidneys play a crucial role in maintaining the right balance of potassium in your body. When potassium levels become too high, it can lead to significant health problems, primarily affecting the heart.

Several factors can cause hyperkalemia. Kidney disease is a major cause, as impaired kidney function can reduce the body’s ability to remove excess potassium. Certain medications, particularly those that affect kidney function, such as ACE inhibitors and some diuretics, can also lead to elevated potassium levels. Dietary intake of potassium, while less commonly a primary cause in individuals with healthy kidney function, can contribute to hyperkalemia in those with pre-existing conditions.
ICD-10-CM Code E87.5: Hyperkalemia Explained
In the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), E87.5 is the specific code used to classify and document hyperkalemia. This code is essential for medical billing, record-keeping, and epidemiological tracking of this condition.
Key details about ICD-10-CM code E87.5:
- Billable/Specific Code: E87.5 is a billable code, meaning it is specific enough to be used for reimbursement purposes in healthcare claims.
- Effective Date: The E87.5 code has been in use since the implementation of ICD-10-CM, with the current version being the 2025 edition, effective October 1, 2024. The code itself has remained consistent through various annual updates, indicating the stable and recognized nature of hyperkalemia as a diagnosis.
- American Standard: E87.5 is the American ICD-10-CM version. It’s important to note that international versions of ICD-10 may have slight variations in coding details.
Applicable terms for E87.5:
The ICD-10-CM system also provides “Applicable To” terms to clarify the scope of the code. For E87.5, these include:
- Potassium [K] excess
- Potassium [K] overload
These terms reinforce that E87.5 is used when there is an excess or overload of potassium in the body.
Synonyms for Hyperkalemia E87.5
Understanding synonyms for a diagnosis code is helpful for broader comprehension and searching related medical information. Approximate synonyms for hyperkalemia (E87.5) include:
- Drug-induced hyperkalemia
- Hyperkalemia (high potassium level)
- Hyperkalemia due to angiotensin-converting enzyme inhibitor
- Hyperkalemia, ACE inhibitor induced
- Hyperkalemia, drug induced
- Potassium intoxication
These synonyms highlight different ways hyperkalemia can be described or its potential causes, such as drug-induced hyperkalemia, which is particularly relevant in patient medical histories where medication is a factor.
Clinical Information and Significance of Hyperkalemia
Clinically, hyperkalemia is identified through laboratory tests that reveal elevated potassium levels in the blood serum. This condition is frequently associated with:
- Kidney Failure: Defective renal excretion is a primary cause, as kidneys are essential for removing excess potassium from the body.
- Medications: Certain drugs, like diuretic drugs and ACE inhibitors, can interfere with potassium regulation and lead to hyperkalemia.
Symptoms and Effects of Hyperkalemia:
Hyperkalemia can manifest in various ways, and its severity can range from mild to life-threatening. Key clinical characteristics include:
- Electrocardiographic (ECG) Abnormalities: These are hallmark signs, including elevated T waves, depressed P waves, and in severe cases, atrial asystole (absence of atrial contraction). ECG changes are crucial for diagnosing and monitoring hyperkalemia.
- Muscle Weakness and Paralysis: In severe hyperkalemia, patients may experience muscle weakness and even flaccid paralysis. This is due to the crucial role of potassium in nerve and muscle function.
Code History of E87.5
The code history for E87.5 shows its consistent presence in the ICD-10-CM system since its inception:
- 2016: New code (first year of non-draft ICD-10-CM) – Established as part of the initial ICD-10-CM implementation.
- 2017-2025: No change – The code has remained unchanged in subsequent annual updates, indicating its continued relevance and accurate representation of hyperkalemia.
This stable code history is important for long-term data analysis and tracking trends related to hyperkalemia.
Relevance in a Broader Context
While hyperkalemia and its diagnosis code E87.5 are primarily within the medical domain, understanding such codes provides valuable insight into diagnostic classification and medical terminology. For professionals working in fields that may indirectly intersect with health information, such as automotive service (where customer health conditions might be relevant context), having a basic awareness of medical codes and conditions like hyperkalemia can be beneficial for general knowledge and a broader understanding of human factors.
Conclusion
The diagnosis code E87.5 for hyperkalemia is a critical tool in the medical field for classifying and managing elevated potassium levels. Understanding the details of this code, its clinical context, and associated terms is essential for healthcare professionals. While the intricacies of ICD-10-CM coding are specific to medical applications, the broader concept of diagnosis codes and their importance in identifying and categorizing health conditions can be valuable knowledge across various professional domains.
