Diffuse alveolar hemorrhage (DAH) is a life-threatening condition caused by a variety of disorders associated with hemoptysis, anemia, diffuse lung infiltration, and acute respiratory failure.
516.9 - Unspecified alveolar and parietoalveolar pneumonopathy | ICD-10-CM.
ICD-10 code R06. 02 for Shortness of breath is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
R53. 81: “R” codes are the family of codes related to "Symptoms, signs and other abnormal findings" - a bit of a catch-all category for "conditions not otherwise specified". R53. 81 is defined as chronic debility not specific to another diagnosis.
ICD-10 code R06. 03 for Acute respiratory distress is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
ICD-10 code J98. 4 for Other disorders of lung is a medical classification as listed by WHO under the range - Diseases of the respiratory system .
1 (Acute cough) R05.
Shortness of breath — known medically as dyspnea — is often described as an intense tightening in the chest, air hunger, difficulty breathing, breathlessness or a feeling of suffocation. Very strenuous exercise, extreme temperatures, obesity and higher altitude all can cause shortness of breath in a healthy person.
R09.02R09. 02 - Hypoxemia | ICD-10-CM.
ICD-10 code R53. 82 for Chronic fatigue, unspecified is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
M62. 81 Muscle Weakness (generalized) Specify etiology of weakness, such as musculoskeletal disorder, stroke, brain injury, etc. R53. 1 Weakness Specify etiology of weakness, such as musculoskeletal disorder, stroke, brain injury, etc.
The 2022 edition of ICD-10-CM R41. 81 became effective on October 1, 2021. This is the American ICD-10-CM version of R41.
ICD-10 code I20. 0 for Unstable angina is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Code R51 is the diagnosis code used for Headache. It is the most common form of pain.
82 Altered mental status, unspecified.
Dyspnea is a symptom of asthma. Environmental pollutants such as chemicals, fumes, dust, and smoke can make it more difficult for people with dyspnea to breathe. People with asthma may find that exposure to allergens such as pollen or mold may trigger episodes of dyspnea.
In 1994, the American European Consensus Conference (AECC) defined acute respiratory distress syndrome (ARDS) as the acute onset of hypoxemia with bilateral infiltrates on frontal chest radiograph, with no evidence of left atrial hypertension ( Am J Respir Crit Care Med 1994;149:818 )
DAD can be seen as a nonspecific manifestation of the agonal phase and shock. Although rarely performed, lung biopsy can be helpful for critical care and prognosis estimation in patients with ARDS.
Diffuse alveolar hemorrhage (DAH) represents a syndrome that can complicate many clinical conditions and may be life-threatening, requiring prompt treatment. It is recognized by the signs of acute- or subacute-onset cough, hemoptysis, diffuse radiographic pulmonary infiltrates, anemia, and hypoxemic respiratory distress.
DAH is characterized by the accumulation of intra-alveolar red blood cells originating most frequently from the alveolar capillaries. It must be distinguished from localized pulmonary hemorrhage, which is most commonly due to chronic bronchitis, bronchiectasis, tumor, or localized infection.
Diffuse alveolar hemorrhage (DAH) is one of the complications of bone marrow or stem cell transplantation presenting as the idiopathic pneumonia syndrome (IPS).
Diffuse alveolar hemorrhage (DAH) is one of the complications of bone marrow or stem cell transplantation presenting as the idiopathic pneumonia syndrome (IPS).
What every physician needs to know: Diffuse alveolar hemorrhage (DAH) is a life-threatening disorder characterized clinically by the presence of hemoptysis, falling hematocrit, diffuse pulmonary infiltrates and hypoxemic respiratory failure. DAH should be considered a medical emergency due to the morbidity and mortality associated ...

Chest radiograph is nonspecific and reveals an alveolar filling process that can be patchy, focal, or diffuse in nature. Chest radiograph can also be used to follow the clinical course of disease.
Pulmonary capillaritis: Neutrophilic infiltration of the alveolar wall and destruction of the capillary leading to hemorrhage into the alveolar sacks.
The most common histopathologic pattern found to cause DAH is pulmonary capillaritis, typically in the setting of a rheumatologic disease or systemic vasculitis.
Alveolar hemorrhage may be the presenting manifestation of granulomatosis with polyangiitis (GPA) in approximately 8% of patients with the disease. It is diagnosed in less than 2–4% of SLE patients; however, the mortality rate approaches 50%. DAH is found in up to 66% of patients in autopsy series. Only 5–10% of cases of Goodpasture syndrome (anti-GBM disease) will have presented with DAH alone. Although the literature about HIV and DAH is limited, a case series of HIV patients with Kaposi sarcoma (KS) found that 75% of these patients had alveolar hemorrhage. There was no effect on 12-month mortality.
Idiopathic. DAH is associated with a number of clinical entities. Pulmonary renal syndromes, connective tissue disorders and drugs make up the majority of the cases of DAH. Hemorrhage originates in the pulmonary microvasculature, rather than from the bronchial circulation or parenchymal abnormalities.
