Inclusion terms

Alternative wording in documentation that is classified to D46.B.

  • RCMD RS

Excludes1 — never code together — inherited from D37-D48

The conditions below can never be reported together with D46.B 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.-)

Use additional code — inherited from D46

Report an additional code alongside D46.B to fully describe the condition. D46.B is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Excludes2 — not included here — inherited from D46

The conditions below are not part of D46.B, but a patient may have both at the same time. When documentation supports it, D46.B and the excluded code may both be reported.

  • drug-induced aplastic anemia (D61.1)

How long has D46.B existed?

D46.B 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.
