exempt from assigning a POA indicator are exempt because they represent a circumstance or a factor influencing health status and do not represent a current disease or injury; and, therefore, are always present on admit. Not addressed, as yet, in the POA guidelines for ICD-10-CM is that fact that the 7. th character
Why ICD-10 codes are important
The ICD-10-CM is a catalog of diagnosis codes used by medical professionals for medical coding and reporting in health care settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates.
ICD-10-CM Code for Acute respiratory failure with hypoxia J96.01 ICD-10 code J96.01 for Acute respiratory failure with hypoxia is a medical classification as listed by WHO under the range - Diseases of the respiratory system .
ICD-10 code G93. 41 for Metabolic encephalopathy is a medical classification as listed by WHO under the range - Diseases of the nervous system .
Whenever “metabolic encephalopathy” is documented, code G93. 41, Metabolic encephalopathy, should be assigned.
P91.60ICD-10-CM Code for Hypoxic ischemic encephalopathy [HIE], unspecified P91. 60.
Metabolic encephalopathy is a problem in the brain. It is caused by a chemical imbalance in the blood. The imbalance is caused by an illness or organs that are not working as well as they should. It is not caused by a head injury. When the imbalance affects the brain, it can lead to personality changes.
If toxic encephalopathy (encephalopathy due to drug) is sequenced as the principal diagnosis, metabolic encephalopathy as a secondary diagnosis will act as an MCC.
Metabolic encephalopathy has been associated with acute insults such as DKA, but importantly, the risk of cerebral injury is also related to chronic hyperglycaemia. Mechanisms of cerebral injury in diabetes mellitus continue to be investigated.
Hypoxic brain damage, also called hypoxic–ischemic encephalopathy, is a severe consequence of global cerebral ischemia due to cardiac arrest [1] or other causes (e.g. hanging, strangulation, poisoning with carbon monoxide or near-drowning).
If you search for toxic encephalopathy, there is the subcategory for metabolic encephalopathy, and both have the code G92. If you look for metabolic encephalopathy, it has the code G93. 41 with the subcategories of drug induced and toxic, both with G92 codes.
Hypoxic refers to a partial lack of oxygen; anoxic means a total lack. In general, the more complete the deprivation, the more severe the harm to the brain and the greater the consequences.
Hepatic encephalopathy: This happens if liver disease causes toxins to build up in a person's blood. Toxic metabolic encephalopathy: This occurs when toxic chemicals, or a chemical imbalance caused by an infection, affects brain function.
There are two major types of metabolic encephalopathies, namely those due to lack of glucose, oxygen or metabolic cofactors (which are usually vitamin-derived) and those due to peripheral organ dysfunction (Table 38-1).
The causes of metabolic encephalopathy are different. The most frequent ones are hypoxia, ischemia, systemic disease, and toxic agents.

neoplasms ( C00-D49) symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified ( R00 - R94) Diseases of the nervous system. Approximate Synonyms. Anoxic brain damage during and/or resulting from a procedure. Anoxic brain damage resulting from a procedure.
Static encephalopathy. Clinical Information. A disorder characterized by a pathologic process involving the brain. A disorder of the brain that can be caused by disease, injury, drugs, or chemicals.
The 2022 edition of ICD-10-CM G93.40 became effective on October 1, 2021.
Metabolic encephalopathy refers to an altered state of consciousness, usually denoting delirium. The delirium is either hypoactive or hyperactive in form, is transient in nature, and is essentially a reversible dysfunction in cerebral metabolism. The term "acute confusional state" may be used by some physicians to describe metabolic encephalopathy. The code assignments in the Alphabetic Index of ICD-9-CM for delirium and acute confusional state are compatible.

Metabolic encephalopathy (delirium) may be designated as principal diagnosis if it is the condition established after study to be chief ly responsible for the ad mission of the patient to the hospital for care . Otherwise, it is listed as an associated condition that exists at time of admission or that develops subsequently.
The ICD10 code for the diagnosis "Metabolic encephalopathy" is "G93.41". G93.41 is a VALID/BILLABLE ICD10 code, i.e it is valid for submission for HIPAA-covered transactions.
The 2019 edition of ICD-10-CM G93.41 became effective on October 1, 2018.
The issue is that there is a specific neonatal entity known by this name and referred to as HIE. The ICD-10-CM code for HIE is P91.6-, subdivided by severity. Perinatal codes are to be used in the first 28 days of life. A condition that arises in adulthood is never coded with a P code. Although “hypoxic-ischemic” describes the mechanism of how the encephalopathy arises in these patients, it will result in a nightmare dilemma for the coders.
Conditions that lead to metabolic encephalopathy are decreased perfusion, hypoxia, electrolyte or glucose disturbances, and sepsis.
The National Institute of Neurological Disorders and Strokes (NINDS) defines encephalopathy as a term for any diffuse disease of the brain that alters function or structure. It has myriad causes, including infection, metabolic or mitochondrial dysfunction, toxins, trauma, poor nutrition, hypoxia, or hypoperfusion of the brain. The hallmark is altered mental status, either in level of consciousness or impaired cognition.
Toxic encephalopathy also risk-adjusts as an MCC.
En cephalopathy from sepsis is categorized as metabolic. It is not caused by an infectious agent directly compromising brain tissue – that would be considered an encephalitis. Also landing in this bucket are electrolyte disturbances, hypoglycemia, hypoxia, and mitochondrial dysfunction.
If a medication is appropriately dosed and the intention is depressed level of consciousness, that would not be considered toxic encephalopathy. In that case, the alteration of consciousness is integral to the medication administration.
I am completely supportive of the conclusion that encephalopathy is a big problem in hospitalized COVID-19 patients, and documenting that encephalopathy specifically and accurately is crucial. I just hope this Neurocritical Care article won’t cause a coding-clinical disconnect.
