Diffuse pleural thickening has new definition for claims

2 Previously it was pleural thickening (of 5 mm or more in a standard chest radiograph) covering 25% or more of the combined area of the chest wall of both lungs if bilateral, or 50% or more if unilateral. 2 Although computed tomography may be used to further substantiate a claim, compensation is usually awarded on the basis of standard chest radiography alone and the extent of respiratory disability.
