icd 9 code for co2 narcosis

Full Answer

What is hypercapnia (CO2 narcosis)?

Hypercapnia, a state of elevated serum carbon dioxide (CO2), can manifest as a broad spectrum of disease, the most severe of which is CO2 narcosis. The delineating feature of CO2 narcosis is a depressed level of consciousness. It is essential to recognize impending or current CO2 narcosis; if left untreated, it can result in coma or death.

How is CO2 narcosis (CO2 syndrome) diagnosed?

The clinician can differentiate CO2 narcosis by both a depressed level of consciousness and hypercapnia. The diagnosis of CO2 narcosis and ruling out other disease processes depends on the clinical presentation, lab findings, and imaging.

What is the prognosis of carbon dioxide (CO2) narcosis?

The prognosis of CO2 narcosis depends on many factors, including the patient's age, comorbidities, underlying etiology, presenting symptoms, the severity of symptoms, and response to therapy. Complications

How is CO2 narcosis related to COPD?

Many patients that develop CO2 narcosis have an acute exacerbation of an underlying chronic disease state, such as COPD. These patients may become frustrated and become distressed by their chronic disease. After the condition resolves, speaking to a psychologist may improve the patient's outlook on the future and frame of mind.

What is the ICD 10 code for carbon monoxide poisoning?

What is the ICD-9 code for hypoxia?

799.02Until now, the ICD-9 code for hypoxia was 799.0. That has changed to the following two new codes, which provide a higher level of specificity: 799.01: asphyxia. 799.02: hypoxemia.

What is the ICD-10 code for respiratory failure?

ICD-10 code J96. 90 for Respiratory failure, unspecified, unspecified whether with hypoxia or hypercapnia is a medical classification as listed by WHO under the range - Diseases of the respiratory system .

How do you test for CO2 poisoning?

The key to confirming the diagnosis is measuring the patient's carboxyhemoglobin (COHgb) level. COHgb levels can be tested either in whole blood or pulse oximeter. It is important to know how much time has elapsed since the patient has left the toxic environment, because that will impact the COHgb level.

What causes hypercapnia?

What Causes Hypercapnia? Hypercapnia occurs when the blood's CO2 level rises above normal due to respiratory problems, excessive metabolism, or more rarely, from breathing in too much CO2. The body produces CO2 as a byproduct of metabolism.

What blood test is done for carbon monoxide poisoning?

The clinical diagnosis of acute carbon monoxide (CO) poisoning should be confirmed by demonstrating an elevated level of carboxyhemoglobin (HbCO). Either arterial or venous blood can be used for testing. Analysis of HbCO requires direct spectrophotometric measurement in specific blood gas analyzers.

What is chronic respiratory failure?

Chronic respiratory failure is a condition that results in the inability to effectively exchange carbon dioxide and oxygen, and induces chronically low oxygen levels or chronically high carbon dioxide levels.

What is the ICD-10 code for chronic respiratory failure with hypoxia?

ICD-10-CM Code for Chronic respiratory failure with hypoxia J96. 11.

What is the ICD-10 code for Acute on chronic respiratory failure with hypoxia and hypercapnia?

ICD-10 Code for Acute and chronic respiratory failure, unspecified whether with hypoxia or hypercapnia- J96. 20- Codify by AAPC.

What is Hypoxemic respiratory failure?

Hypoxemic respiratory failure means that you don't have enough oxygen in your blood, but your levels of carbon dioxide are close to normal. Hypercapnic respiratory failure means that there's too much carbon dioxide in your blood, and near normal or not enough oxygen in your blood.

What is CO2 narcosis?

Carbon dioxide (CO2) narcosis is a condition that develops when excessive CO2 is present in the bloodstream, leading to a depressed level of consciousness. This condition largely results from lung disease, hypoventilation, or environmental exposure. This activity reviews the evaluation and treatment of CO2 narcosis and highlights the role ...

Why is non-invasive ventilation inappropriate for CO2 narcosis?

Non-invasive ventilation is inappropriate for patients with CO2 narcosis due to the high risk of aspiration of gastric contents.

What is a depressed level of consciousness?

Patients that present with a depressed level of consciousness have a broad differential, and many etiologies need to be considered, such as toxins, sedative drugs, metabolic derangements, infections, and supratentorial or infratentorial abnormalities. [28] The clinician can differentiate CO2 narcosis by both a depressed level of consciousness and hypercapnia. The diagnosis of CO2 narcosis and ruling out other disease processes depends on the clinical presentation, lab findings, and imaging.

How to treat COPD hypercapnia?

The goal of therapy is to determine the underlying cause and correct the hypercapnia. If the patient is having a COPD exacerbation, treat the patient with bronchodilators and steroids. In patients with suspected overdose, consider antidotes for reversal of sedative medications such as naloxone for opiate overdose. If the patient has significant pneumonia, it is necessary to include antibiotics in the treatment. If the patient has developed anaphylaxis that has threatened their airway, they need to be intubated and started on therapies including H1 and H2 blockers, corticosteroids, and epinephrine. If the patient already has a depressed level of consciousness, with poor respiratory effort or impending respiratory failure, they need to be intubated, followed by mechanical ventilation. Non-invasive ventilation is inappropriate for patients with CO2 narcosis due to the high risk of aspiration of gastric contents. These patients require admission to the ICU for close monitoring. A repeat ABG analysis is needed to monitor for improvement of PaCO2 while undergoing mechanical ventilation. If the patient has new-onset acute hypercapnia, the goal is a correction to normocapnia. If the patient has acute on chronic hypercapnia, the goal is back to the patient's baseline levels. [8] In the rare case that the individual had environmental exposure to high levels of carbon dioxide, the first step is to remove the individual from the environment and then treat accordingly, as stated above.

How does CO2 affect cerebral blood flow?

Cerebral autoregulation is a process in which the brain works to maintain a constant and steady supply of nutrients and oxygen despite changes in cerebral perfusion pressure. CO2 plays a fundamental role in the regulation of cerebral blood flow. The belief is that changes in PaCO2 drive changes in the pH of the cerebral spinal fluid, causing relaxation or contraction of the smooth muscle. As PaCO2 levels rise, cerebral blood vessels dilate, and as PaCO2 levels drop, cerebral blood vessels constrict. [9] In patients with CO2 narcosis, the smooth muscle will relax, causing dilation of cerebral blood vessels, increasing cerebral blood flow, potentially causing increased intracranial pressure.

What is the state of CO2?

Hypercapnia, a state of elevated serum carbon dioxide (CO2), can manifest as a broad spectrum of disease, the most severe of which is CO2 narcosis. The delineating feature of CO2 narcosis is a depressed level of consciousness. It is essential to recognize impending or current CO2 narcosis; if left untreated, it can result in coma or death. This article primarily focuses on CO2 narcosis, but it is crucial to appreciate that hypercapnia has multiple end-organ effects contributing to the patient's deterioration. Many etiologies contribute to hypercapnia; the most commonly encountered is chronic obstructive pulmonary disease (COPD). Treatment is focused on fixing the underlying cause and demands an interprofessional approach to optimize patient outcomes.

What is the driving mechanism of CO2 narcosis?

Etiology. Overall, the driving mechanism of CO2 narcosis is acute hypercapnia. The etiology can be extensive, but it can be helpful to divide the potential causes into three groups: decreased minute ventilation, increased physiologic dead space, increased carbon dioxide production. [1]

What is the delineating feature of CO2 narcosis?
