Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Chronic fatigue syndrome
- ME/CFS
- Myalgic encephalomyelitis
Other codes that can never be billed with G93.32
These codes carry an Excludes1 note pointing at G93.32. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G93.32 alone.
Risk adjustment
G93.32 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
G93.32 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
