About coding bronchial adenoma
The ICD-10-CM code for bronchial adenoma is D38.1 (Neoplasm of uncertain behavior of trachea, bronchus and lung).
Within D38 (neoplasm of uncertain behavior of middle ear and respiratory and intrathoracic organs), D38.1 is specifically for neoplasm of uncertain behavior of trachea, bronchus and lung. Related codes cover larynx (D38.0), pleura (D38.2), mediastinum (D38.3), thymus (D38.4), other respiratory organs (D38.5) and respiratory organ, unspecified (D38.6).
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.
