About coding lymphocytic colitis
The ICD-10-CM code for lymphocytic colitis is K52.832 (Lymphocytic colitis).
Within K52.83 (microscopic colitis), K52.832 is specifically for lymphocytic colitis. Related codes cover Collagenous colitis (K52.831), other microscopic colitis (K52.838) and unspecified (K52.839).
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 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive 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.
