Which MS-DRGs does D55.0 group to?
D55.0 sits in MDC 16 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

How is D55.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to D55.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Favism (anemia)
- Anemia › Baghdad spring (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Anemia › favism (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Anemia › glucose-6-phosphate dehydrogenasedeficiency (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Poisoning › fava bean (acute)
- Toxicity › fava bean
- Anemia › deficiency › glucose-6-phosphate dehydrogenase (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Anemia › deficiency › G6PD (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Deficiency, deficient › glucose-6-phosphate dehydrogenase › anemia
- Anemia › deficiency › enzyme › glucose-6-phosphate dehydrogenase (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
- Anemia › hemolytic › nonspherocytic › congenital or hereditary NEC › glucose-6-phosphate dehydrogenase deficiency (essential) (general) (hemoglobin deficiency) (infantile) (primary) (profound)
Excludes1 — never code together
The conditions below can never be reported together with D55.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A)
Inclusion terms
Alternative wording in documentation that is classified to D55.0.
- Favism
- G6PD deficiency anemia
Excludes1 — never code together — inherited from D55
The conditions below can never be reported together with D55.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- drug-induced enzyme deficiency anemia (D59.2)
Excludes2 — not included here — inherited from Chapter 3
The conditions below are not part of D55.0, but a patient may have both at the same time. When documentation supports it, D55.0 and the excluded code may both be reported.
- 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)
- endocrine, nutritional and metabolic diseases (E00-E88)
- human immunodeficiency virus [HIV] disease (B20)
- 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)
How long has D55.0 existed?
D55.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with D55.0?
ICD-10-CM declares these codes mutually exclusive with D55.0 — exactly one of each pair can be correct for a given encounter.
