There are three phases in the reaction of the lungs to radiation injury: an acute phase occurring 1 to 2 months after exposure, a subacute phase 2 to 9 months after exposure, and a chronic or fibrotic phase more than 9 months after exposure. In the acute phase there is vascular damage, congestion, edema, and mononuclear cell infiltration; in the subacute phase the alveolar walls are infiltrated with mononuclear inflammatory cells and fibroblasts; in the chronic phase, alveolar fibrosis and capillary sclerosis take place. 508.0 is a specific code that can be used to specify a diagnosis 508.0 contains 7 index entries View the ICD-9-CM Volume 1 508.* hierarchy Alternate Terminology Radiation pneumonitis  Index entries containing 508.0: Condition - see also Disease respiratory NEC 519.9 acute or subacute NEC 519.9 due to radiation 508.0 Edema, edematous 782.3 lung 514 acute 518.4 due to radiation 508.0 Effect, adverse NEC radiation (diagnostic) (fallout) (infrared) (natural source) (therapeutic) (tracer) (ultraviolet) (x-ray) NEC 990 with pulmonary manifestations acute 508.0 pneumonitis 508.0 Pneumonia (acute) (Alpenstich) (benign) (bilateral) (brain) (cerebral) (circumscribed) (congestive) (creeping) (delayed resolution) (double) (epidemic) (fever) (flash) (fulminant) (fungoid) (granulomatous) (hemorrhagic) (incipient) (infantile) (infectious) (infiltration) (insular) (intermittent) (latent) (lobe) (migratory) (newborn) (organized) (overwhelming) (primary) (progressive) (pseudolobar) (purulent) (resolved) (secondary) (senile) (septic) (suppurative) (terminal) (true) (unresolved) (vesicular) 486 radiation 508.0 Pneumonitis (acute) (primary) (see also Pneumonia) 486 radiation 508.0 Poisoning (acute) - see also Table of Drugs and Chemicals radiation 508.0
