Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Developmental disorder NOS
- Neurodevelopmental disorder NOS
Other codes that can never be billed with F89
These codes carry an Excludes1 note pointing at F89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F89 alone.
- Z55Problems related to education and literacy
Risk adjustment
F89 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
F89 is named in 6 Medicare coverage policies — 5 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How F89 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to F89.
