M35.0 — Sjogren syndrome
M35.0 is a non-billable header ICD-10-CM code for sjogren syndrome. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- dry mouth, unspecified (R68.2)
Use additional code
Add a secondary code to capture the detail described below.
- code to identify associated manifestations
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Sicca syndrome
Other codes that can never be billed with M35.0
These codes carry an Excludes1 note pointing at M35.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M35.0 alone.
Risk adjustment
M35.0 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.
