High levels of lactic acid. This probably means you have bacterial meningitis. Normal or slightly high levels of lactic acid. This probably means you have a viral form of the infection. If you have questions about your results, talk to your health care provider. Learn more about laboratory tests, reference ranges, and understanding results.
What is a normal lactic acid level? A normal blood lactate level is 0.5-1 mmol/L. A level > 4 mmol/L defines lactic acidosis3, a level high enough to tip the acid-base balance, which may result in a serum pH < 7.35 in association with metabolic acidosis.
While high lactic acid levels in response to physical exertion should not pose a risk for otherwise healthy people, lactic acidosis can increase the risk of serious complications and even death in people who are already ill. Always immediately seek medical help if you develop signs of lactic acidosis.
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.
R740 - ICD 10 Diagnosis Code - Nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH] - Market Size, Prevalence, Incidence, Quality Outcomes, Top Hospitals & Physicians.
R74. 0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM R74.
Lactic acidosis, which occurs when there's too much lactic acid in your body. Causes can include chronic alcohol use, heart failure, cancer, seizures, liver failure, prolonged lack of oxygen, and low blood sugar. Even prolonged exercise can lead to lactic acid buildup.
Lactic acidosis shares the ICD-10-CM code, E87. 2, Acidosis, with other causes of acidosis, respiratory or metabolic.
ICD-10-CM Code for Elevation of levels of lactic acid dehydrogenase [LDH] R74. 02.
0 for Nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH] is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
Lactic acidosis occurs when lactic acid production exceeds lactic acid clearance. The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization. (See "Approach to the adult with metabolic acidosis".)
Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body's oxygen level might drop include: During intense exercise.
A higher-than-normal lactic acid level in your blood can also be a sign of problems with your metabolism. And, your body might need more oxygen than normal because you have one of the following conditions: Liver disease. Kidney disease. Diabetes that's not under control.
Normal lactate levels are less than two mmol/L, with hyperlactatemia defined as lactate levels between 2 mmol/L and 4 mmol/L. Severe levels of lactate are 4 mmol/L or higher.
Lactate is a chemical naturally produced by the body to fuel the cells during times of stress. Its presence in elevated quantities is commonly associated with sepsis and severe inflammatory response syndrome.
Muscle ache, burning, rapid breathing, nausea, stomach pain: If you've experienced the unpleasant feeling of lactic acidosis, you likely remember it. Lactic acidosis caused by intense exercise is usually temporary. It happens when too much acid builds up in your bloodstream.
In our retrospective cohort study, severe sepsis or septic shock patients admitted to the ICU from the ED with initial blood lactate more than 2.5 mmol/L were at increased risk of death.
My last piece of advice relates to one of those coding-clinical disconnects. Hyperlactatemia is the way providers describe elevated lactate short of lactic acidosis. There is no indexing for hyperlactatemia. The ICD-10-CM indexing will take “excessive lacticemia” to E87.2. However, this is not a phrase that clinicians use. You may want to set up an internal coding guideline stating that your providers use “hyperlactatemia” to indicate “excessive lacticemia,” or set up an acronym expansion that outputs “hyperlactatemia, i.e., excessive lacticemia,” when the clinician types in “hyperlactatemia.”
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.
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.
Stronger acids have a high degree of ionization, so there are relatively more free hydrogen ions floating around. pH, standing for “power of hydrogen,” is a logarithmic scale representing how acidic or alkaline a solution is. pH is based on the concentration of H+ ions. A reading of 7.0 is considered neutral, but there are still hydrogen ions around, 10 -7 to be precise. Less than 7.0 is acidic, more than 7.0 is alkaline or basic. Normal body pH is 7.4.
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.
The 2022 edition of ICD-10-CM R74.0 became effective on October 1, 2021.
R74.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
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:

DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically.
