D47.9 — Neoplasm of uncertain behavior of lymphoid, hematopoietic and related tissue, unspecified

BillableUnspecifiedCC

Is D47.9 billable?

Yes, but D47.9 is an unspecified code. D47.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D47.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting D47.9 — the more specific alternatives are listed below.

Which MS-DRGs does D47.9 group to?

D47.9 sits in MDC 17 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 820Lymphoma and Leukemia with Major O.R. Procedures with MCCsurgical
  • 821Lymphoma and Leukemia with Major O.R. Procedures with CCsurgical
  • 822Lymphoma and Leukemia with Major O.R. Procedures without CC/MCCsurgical

As a secondary diagnosis, D47.9 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is D47.9 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to D47.9. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Disease, diseased › lymphoproliferative

Inclusion terms

  • Lymphoproliferative disease NOS

Excludes1 — never code together — inherited from D37-D48

The conditions below can never be reported together with D47.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • neoplasms of unspecified behavior (D49.-)

How long has D47.9 existed?

D47.9 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
