About coding pneumoconiosis
The ICD-10-CM code for pneumoconiosis is J64 (Unspecified pneumoconiosis). The official index lists 30 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J64.
Don't report J64 together with the conditions in its Excludes1 note: pneumonoconiosis with tuberculosis, any type in A15 (J65).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
