Excludes1 inherited from the categories above F15.90

These are not written on F15.90, but they bind it: a note on a category applies to every code beneath it. Billing F15.90 with anything listed here is a denial.

Written on F15.9 Other stimulant use, unspecified

  • other stimulant abuse (F15.1-)
  • other stimulant dependence (F15.2-)

Excludes2 inherited from the categories above F15.90

Also inherited, and the opposite of Excludes1: these conditions are not part of F15.90, but a patient can have both, so you may code both.

  • cocaine-related disorders (F14.-)

Risk adjustment

F15.90 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

F15.90 is named in 11 Medicare coverage policies 9 listing it as supporting medical necessity, and 2 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
