About D17.9
D17.9 is the ICD-10-CM diagnosis code for benign lipomatous neoplasm, unspecified. It belongs to category D17 (benign lipomatous neoplasm), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within D17, choose D17.9 (unspecified) only when documentation doesn't support a more specific option: of skin and subcutaneous tissue of head, face and neck (D17.0), of skin and subcutaneous tissue of trunk (D17.1), of skin and subcutaneous tissue of limb (D17.2), of skin and subcutaneous tissue of other and unspecified sites (D17.3), of intrathoracic organs (D17.4), of intra-abdominal organs (D17.5), of spermatic cord (D17.6) and of other sites (D17.7).
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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 214.9 (Lipoma, unspecified site).
