Diagnostic Code 6826 · 38 CFR §4.97
Desquamative interstitial pneumonitis (DIP) is a rare form of interstitial lung disease characterized by the accumulation of macrophages (immune cells) in the tiny air sacs of the lungs. This buildup causes inflammation and progressive scarring that makes breathing increasingly difficult. DIP is strongly associated with cigarette smoking, but can also develop from occupational exposures to dusts, chemicals, or fumes common in military settings. Veterans exposed to burn pit smoke, industrial chemicals, or other inhaled irritants during service may develop this condition. Symptoms include progressive shortness of breath, dry cough, and declining exercise tolerance. The VA rates DIP under the General Rating Formula for Interstitial Lung Disease, which uses pulmonary function test results to determine the rating level.
