About coding alveolar adenoma
The ICD-10-CM code for alveolar adenoma is D14.30 (Benign neoplasm of unspecified bronchus and lung).
Within D14.3, choose D14.30 (unspecified bronchus and lung) only when documentation doesn't support a more specific option: right bronchus and lung (D14.31) and left bronchus and lung (D14.32).
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 180 (Respiratory Neoplasms with MCC, relative weight 1.7806), DRG 181 (Respiratory Neoplasms with CC, relative weight 1.0936) and DRG 182 (Respiratory Neoplasms without CC/MCC, relative weight 0.7439), 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.
