Code Classification

  • Diseases of the respiratory system
    • Other respiratory diseases principally affecting the interstitium
      • Other interstitial pulmonary diseases

J84.10 is a billable diagnosis code used to specify a medical diagnosis of pulmonary fibrosis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like J84.10 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information

  • Asbestosis - a form of pneumoconiosis caused by inhalation of asbestos fibers which elicit potent inflammatory responses in the parenchyma of the lung. the disease is characterized by interstitial fibrosis of the lung, varying from scattered sites to extensive scarring of the alveolar interstitium.
  • Idiopathic Pulmonary Fibrosis - a common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive dyspnea. pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.
  • Pulmonary Fibrosis - a process in which normal lung tissues are progressively replaced by fibroblasts and collagen causing an irreversible loss of the ability to transfer oxygen into the bloodstream via pulmonary alveoli. patients show progressive dyspnea finally resulting in death.
  • Invasive Pulmonary Aspergillosis - lung infections with the invasive forms of aspergillus, usually after surgery, transplantation, prolonged neutropenia or treatment with high-doses of corticosteroids. invasive pulmonary aspergillosis can progress to chronic necrotizing pulmonary aspergillosis or hematogenous spread to other organs.
  • Pulmonary Aspergillosis - infections of the respiratory tract with fungi of the genus aspergillus.
  • Aspergillus - a genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family trichocomaceae.
  • Dyspnea - difficult or labored breathing.
  • Localized Pulmonary Fibrosis - replacement of the lung tissue by connective tissue in a specific area of the lung.
  • Chronic Pulmonary Aspergillosis - a spectrum of disorders associated with long-term aspergillus infection of the lung that usually occur in immunocompetent individuals with underlying respiratory disorders, and may be characterized by pulmonary fibrosis or cavitation.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Pulmonary Fibrosis

Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen.

Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis.

Symptoms include:

  • Shortness of breath
  • A dry, hacking cough that doesn't get better
  • Fatigue
  • Weight loss for no known reason
  • Aching muscles and joints
  • Clubbing, which is the widening and rounding of the tips of the fingers or toes

Your doctor may use your medical history, imaging tests, a biopsy, and lung function tests to diagnose pulmonary fibrosis. There is no cure. Treatments can help with symptoms and improve your quality of life. They include medicines, oxygen therapy, pulmonary rehabilitation, or a lung transplant.

Idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis is a chronic, progressive lung disease. This condition causes scar tissue (fibrosis) to build up in the lungs, which makes the lungs unable to transport oxygen into the bloodstream effectively. The disease usually affects people between the ages of 50 and 70. Idiopathic pulmonary fibrosis belongs to a group of conditions called interstitial lung diseases (also known as ILD), which describes lung diseases that involve inflammation or scarring in the lung.

The most common signs and symptoms of idiopathic pulmonary fibrosis are shortness of breath and a persistent dry, hacking cough. Many affected individuals also experience a loss of appetite and gradual weight loss. Some people with idiopathic pulmonary fibrosis develop widened and rounded tips of the fingers and toes (clubbing) resulting from a shortage of oxygen. These features are relatively nonspecific; not everyone with these health problems has idiopathic pulmonary fibrosis. Other respiratory diseases, some of which are less serious, can cause similar signs and symptoms.

In people with idiopathic pulmonary fibrosis, scarring of the lungs increases over time until the lungs can no longer provide enough oxygen to the body's organs and tissues. Some people with idiopathic pulmonary fibrosis develop other serious lung conditions, including lung cancer, blood clots in the lungs (pulmonary emboli), pneumonia, or high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension). Most affected individuals survive 3 to 5 years after their diagnosis. However, the course of the disease is highly variable; some affected people become seriously ill within a few months, while others may live with the disease for a decade or longer.

In most cases, idiopathic pulmonary fibrosis occurs in only one person in a family. These cases are described as sporadic. However, a small percentage of people with this disease have at least one other affected family member. When idiopathic pulmonary fibrosis occurs in multiple members of the same family, it is known as familial pulmonary fibrosis.

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
