R68.2 — Dry mouth, unspecified
R68.2 is a billable, specific ICD-10-CM code for dry mouth, unspecified. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- salivary gland hyposecretion (K11.7)
Other codes that can never be billed with R68.2
These codes carry an Excludes1 note pointing at R68.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R68.2 alone.
- M35.0Sjogren syndrome
Risk adjustment
R68.2 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.
How R68.2 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 R68.2.
