About coding pneumonectomy status
The ICD-10-CM code for pneumonectomy status is Z90.2 (Acquired absence of lung [part of]).
Within Z90 (acquired absence of organs, not elsewhere classified), Z90.2 is specifically for acquired absence of lung [part of]. Related codes cover part of head and neck (Z90.0), breast and nipple (Z90.1), stomach [part of] (Z90.3), other specified parts of digestive tract (Z90.4), kidney (Z90.5), other parts of urinary tract (Z90.6), genital organ(s) (Z90.7) and other organs (Z90.8).
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 205 (Other Respiratory System Diagnoses with MCC, relative weight 1.8244) and DRG 206 (Other Respiratory System Diagnoses without MCC, relative weight 0.9257), 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.
