Which MS-DRGs does D57.433 group to?

D57.433 sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Two codes may be needed to describe the condition fully. Whether D57.433 is sequenced first depends on the reason for the encounter.

  • , if applicable cerebral infarction (I63.-)

Inclusion terms

Alternative wording in documentation that is classified to D57.433.

  • HbS-beta zero with cerebral vascular involvement
  • Sickle-cell beta zero with cerebral vascular involvement

Excludes1 — never code together — inherited from D57

The conditions below can never be reported together with D57.433 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • other hemoglobinopathies (D58.-)

Use additional code — inherited from D57

Report an additional code alongside D57.433 to fully describe the condition. D57.433 is sequenced first.

  • code for any associated fever (R50.81)

Excludes2 — not included here — inherited from Chapter 3
