Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Renal tubular acidosis in sicca syndrome
Other codes that can never be billed with M35.04
These codes carry an Excludes1 note pointing at M35.04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M35.04 alone.
- N16Renal tubulo-interstitial disorders in diseases classified elsewhere
Risk adjustment
M35.04 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
M35.04 is named in 13 Medicare coverage policies — 7 listing it as supporting medical necessity, and 6 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
