About coding Angiocentric immunoproliferative lesion
The ICD-10-CM code for Angiocentric immunoproliferative lesion is D47.Z9 (Other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue).
Within D47.Z, choose D47.Z9 (Other specified neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue) only when documentation doesn't support a more specific option: Post-transplant lymphoproliferative disorder (PTLD) (D47.Z1) and Castleman disease (D47.Z2).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC, relative weight 6.2481), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC, relative weight 2.2023), DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC, relative weight 1.1272), DRG 823 (Lymphoma and Non-Acute Leukemia with Other Procedures with MCC, relative weight 4.6059), DRG 824 (Lymphoma and Non-Acute Leukemia with Other Procedures with CC, relative weight 2.2515), DRG 825 (Lymphoma and Non-Acute Leukemia with Other Procedures without CC/MCC, relative weight 1.2995) and 3 more, in MDC 17 (Myeloproliferative Diseases and Disorders, Poorly Differentiated Neoplasms), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
