Use additional code

Add a secondary code to capture the detail described below.

code for adverse effect, if applicable, to identify drug (T45.1X5)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

underlying neoplasm

Excludes1 inherited from the categories above D70.1

These are not written on D70.1, but they bind it: a note on a category applies to every code beneath it. Billing D70.1 with anything listed here is a denial.

Written on D70 — Neutropenia

neutropenic splenomegaly (D73.81)
transient neonatal neutropenia (P61.5)

Risk adjustment

D70.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

D70.1 is named in 14 Medicare coverage policies — 14 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
