About D48.7

D48.7 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of other specified sites. It belongs to category D48 (neoplasm of uncertain behavior of other and unspecified sites), block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) 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 D48, choose D48.7 (behavior of other specified sites) only when documentation doesn't support a more specific option: behavior of bone and articular cartilage (D48.0), behavior of connective and other soft tissue (D48.1), behavior of peripheral nerves and autonomic nervous system (D48.2), behavior of retroperitoneum (D48.3), behavior of peritoneum (D48.4), behavior of skin (D48.5), behavior of breast (D48.6) and behavior, unspecified (D48.9).

Don't report D48.7 together with the conditions in its Excludes1 note: neoplasm of uncertain behavior of connective tissue (D48.1-) and neoplasm of uncertain behavior of skin of eyelid (D48.5).

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 826 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures with MCC, relative weight 4.7581), DRG 827 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures with CC, relative weight 2.3896), DRG 828 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures without CC/MCC, relative weight 1.6955), DRG 829 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Other Procedures with CC/MCC, relative weight 3.1281), DRG 830 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Other Procedures without CC/MCC, relative weight 1.4859), DRG 843 (Other Myeloproliferative Disorders or Poorly Differentiated Neoplastic Diagnoses with MCC, relative weight 1.9453) and 2 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.

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 238.8 (neoplasm of uncertain behavior of other specified sites).
