About D03.72

D03.72 is the ICD-10-CM diagnosis code for melanoma in situ of left lower limb, including hip. It belongs to category D03 (melanoma in situ), block D00-D09 (in situ neoplasms) 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 D03.7 (melanoma in situ of lower limb, including hip), D03.72 is specifically for melanoma in situ of left lower limb, including hip. Related codes cover unspecified lower limb, including hip (D03.70) and right lower limb, including hip (D03.71).

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 595 (Major Skin Disorders with MCC, relative weight 2.0239) and DRG 596 (Major Skin Disorders without MCC, relative weight 1.1071), 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 172.7 (malignant melanoma of skin of lower limb, including hip).
