Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- IQ 20-25 to 35-40
- Severe mental subnormality
Risk adjustment
F72 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
F72 is named in 13 Medicare coverage policies — 10 listing it as supporting medical necessity, and 3 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
