ICD-10 code for fetal lipoma

The ICD-10-CM code for fetal lipoma is D17.9 (Benign lipomatous neoplasm, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D17.9.

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.
