What Does a High Level of Lactic Acid Mean? According to WebMD, high levels of lactic acid mean that the body’s lactate threshold, also known as the anaerobic threshold, has been passed, and that lactic acid is building up in the kidneys and liver.
There are some health circumstances or drugs than can raise your LDH level in the blood:
Lactic acidosis shares the ICD-10-CM code, E87. 2, Acidosis, with other causes of acidosis, respiratory or metabolic.
2022 ICD-10-CM Diagnosis Code R74. 0: Nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH]

What is a lactate dehydrogenase (LDH) test? This test measures the level of lactate dehydrogenase (LDH), also known as lactic acid dehydrogenase, in your blood or sometimes in other body fluids. LDH is a type of protein, known as an enzyme. LDH plays an important role in making your body's energy.
The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization.
A high lactate level in the blood means that the disease or condition a person has is causing lactate to accumulate. In general, a greater increase in lactate means a greater severity of the condition. When associated with lack of oxygen, an increase in lactate can indicate that organs are not functioning properly.
Lactate acidosis is a common finding in diabetic ketoacidosis (DKA). Lactate acidosis in DKA is multifactorial in aetiology— anaerobic glycolysis due to inadequate tissue perfusion and oxygenation as well as the metabolic derangements itself present in DKA might contribute to the elevated lactate levels.
ICD-10 code E87. 2 for Acidosis is a medical classification as listed by WHO under the range - Endocrine, nutritional and metabolic diseases .
From a coding standpoint, ICD-10 code A41. x series do not have Excludes 1 notes for acidosis and the acidosis E codes do not have Excludes 1 notes for sepsis.
Lactic Acid and Lactate are extremely similar; they only differ by a single hydrogen atom! That hydrogen is very important though… to be an acid, a molecule needs to have an extra hydrogen ion to donate. If lactic acid donated that extra proton it has from the hydrogen atom, it would become lactate.
Lactic acidosis develops when there is increased production of lactate, decreased clearance, or a combination of both. The most common cause is the shock state. It can also result from impaired hepatic function, like in cirrhosis, or from regional ischemia, drugs and toxins, or from inborn errors of metabolism.
Hyperlactatemia is a blood level of lactate from 2 to 4 mmol/L. Lactic acidosis is defined as lactate level > 4 mmol/L. There is often acidemia, which means the blood measures acidic (relative to normal pH of 7.4) with a pH < 7.35, but if compensatory mechanisms are not overwhelmed, the pH may be closer to normal.
We measure the lactate because it is a marker for how excessive the available hydrogen ions are. If compensatory mechanisms are in place, such as buffering or physiological hyperventilation, the pH may not nosedive. Some lactic acid and lactate production is normal.
Some lactic acid and lactate production is normal. There are some cells that only can utilize glucose as an energy source, as opposed to protein or fatty acids, such as red blood cells. The brain preferentially uses glucose. Glucose is broken down into a compound called pyruvate, releasing some energy.
If the condition indexes under a general term coded at E87.2, like acidosis or acidemia, it is integral to it. Examples are renal tubular acidosis or propionic acidemia. They code to different codes, but they are indexed below E87.2. Genetic disorders of metabolism can have variable manifestations.
Genetic disorders of metabolism can have variable manifestations. If acidemia is part of the name of the condition and the condition is indexed below E87.2, acidosis should be considered inherent. Other inborn errors, however, may have lactic acidosis as a component.
R74.02 is new to ICD-10 code set for the FY 2021, effective October 1, 2020. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2020. This is a new and revised code for the FY 2021 (October 1, 2020 - September 30, 2021).
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code (s). The following references for the code R74.02 are found in the index:
