Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D77: its own notes plus those printed at Chapter 3. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • rupture of spleen due to Plasmodium vivax malaria (B51.0)
  • splenitis, splenomegaly in late syphilis (A52.79)
  • splenitis, splenomegaly in tuberculosis (A18.85)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 3 (D50-D89) Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism applies to 324 codes
  • autoimmune disease (systemic) NOS (M35.9)
  • certain conditions originating in the perinatal period (P00-P96)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)

  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Questions About D77Overview

Is D77 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other disorders of blood and blood-forming organs in diseases classified elsewhere on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does D77 group to?

On inpatient claims, other disorders of blood and blood-forming organs in diseases classified elsewhere maps to MS-DRG 816, 814, 815, with relative weights from 0.7378 to 2.0727 depending on complications. Higher weights mean higher Medicare reimbursement.

Can D77 be a principal diagnosis?

No. This is a manifestation code: other disorders of blood and blood-forming organs in diseases classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.

Can D77 be reported with B51.0?

Not as a rule. The Excludes1 note on D77 lists "rupture of spleen due to Plasmodium vivax malaria (B51.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is coded first with D77?

The Code First note reads: underlying disease, such as: amyloidosis (E85.-); congenital early syphilis (A50.0-); echinococcosis (B67.0-B67.9); malaria (B50.0-B54); schistosomiasis [bilharziasis] (B65.0-B65.9); and 1 more listed in the Instructional Notes section. When one of these applies, it is sequenced before D77.
