2026 ICD-10-CM Diagnosis Code P74.1

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Clinical Information

• Dehydration

  the condition that results from excessive loss of water from a living organism.

Convert P74.1 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Fluid and Electrolyte Balance

What are electrolytes?

Electrolytes are minerals that have an electric charge when they are dissolved in water or body fluids, including blood. The electric charge can be positive or negative. You have electrolytes in your blood, urine (pee), tissues, and other body fluids.

Electrolytes are important because they help:

• Balance the amount of water in your body
• Balance your body's acid/base (pH) level
• Move nutrients into your cells
• Move wastes out of your cells
• Support your muscle and nerve function
• Keep your heart rate and rhythm steady
• Keep your blood pressure stable
• Keep your bones and teeth healthy

What are the different types of electrolytes in your body?

The main electrolytes in your body include:

• Bicarbonate, which helps maintain the body's acid and base balance (pH). It also plays an important role in moving carbon dioxide through the bloodstream.
• Calcium, which helps make and keep bones and teeth strong.
• Chloride, which also helps control the amount of fluid in the body. In addition, it helps maintain healthy blood volume and blood pressure.
• Magnesium, which helps your muscles, nerves, and heart work properly. It also helps control blood pressure and blood glucose (blood sugar).
• Phosphate, which works together with calcium to build strong bones and teeth.
• Potassium, which helps your cells, heart, and muscles work properly.
• Sodium, which helps control the amount of fluid in the body. It also helps your nerves and muscles work properly.

You get these electrolytes from the foods you eat and the fluids you drink.

What is an electrolyte imbalance?

An electrolyte imbalance means that the level of one or more electrolytes in your body is too low or too high. It can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some of the more common reasons why you might have an imbalance of the water in your body include:

• Certain medicines
• Severe vomiting and/or diarrhea
• Heavy sweating
• Heart, liver or kidney problems
• Not drinking enough fluids, especially when doing intense exercise or when the weather is very hot
• Drinking too much water

What are the different types of electrolyte imbalances?

The names of the different types of electrolyte imbalances are:

How are electrolyte imbalances diagnosed?

A test called an electrolyte panel can check the levels of your body's main electrolytes. A related test, the anion gap blood test, checks whether your electrolytes are out of balance or if your blood is too acidic or not acidic enough.

What are the treatments for electrolyte imbalances?

The treatment for an electrolyte imbalance depends on which electrolytes are out of balance, if there is too little or too many, and what is causing the imbalance. In minor cases, you may just need to make some changes to your diet. In other cases, you may need other treatments. For example:

• If you don't have enough of an electrolyte, you may get electrolyte replacement therapy. This involves giving you more of that electrolyte. It could be a medicine or supplement that you swallow or drink, or it may be given intravenously (by IV).
• If you have too much of an electrolyte, your provider may give you medicines or fluids (by mouth or by IV) to help remove that electrolyte from your body. In severe cases, you may need dialysis to filter out the electrolyte.

Uncommon Infant and Newborn Problems

It can be scary when your baby is sick, especially when it is not an everyday problem like a cold or a fever. You may not know whether the problem is serious or how to treat it. If you have concerns about your baby's health, call your health care provider right away.

Learning information about your baby's condition can help ease your worry. Do not be afraid to ask questions about your baby's care. By working together with your health care provider, you make sure that your baby gets the best care possible.
