504Pneumonopathy due to inhalation of other dust
- Legacy / Not Valid for Submission
- Replaced October 1, 2015
504 is a legacy ICD-9-CM diagnosis code for pneumonopathy due to inhalation of other dust. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, it maps to 4 ICD-10-CM candidates: J66.0, J66.1, J66.2, and J66.8.

Questions About 504
Is 504 (pneumonopathy due to inhalation of other dust) still a valid code?
No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as J66.0, J66.1, and J66.2.
What is the ICD-10 replacement for 504?
The General Equivalence Mappings list 4 ICD-10-CM candidates for this code: J66.0 (Byssinosis), J66.1 (Flax-dressers' disease), J66.2 (Cannabinosis), and J66.8 (Airway disease due to other specific organic dusts). Each match is approximate, so the right choice depends on what the documentation supports.
What did 504 mean?
In the final ICD-9-CM release, this code described pneumonopathy due to inhalation of other dust. It sat in block 504 Pneumopathy due to inhalation of other dust under Diseases of the respiratory system (460–519).
Why does 504 map to more than one ICD-10 code?
ICD-10-CM is more specific than ICD-9-CM. The detail packed into this single legacy code was split across J66.0, J66.1, J66.2, and J66.8, so the General Equivalence Mappings list every candidate rather than forcing one. The correct target is the one the documentation supports.
