About R68.2
R68.2 is the ICD-10-CM diagnosis code for dry mouth, unspecified. It belongs to category R68 (other general symptoms and signs), block R50-R69 (general symptoms and signs) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within R68, choose R68.2 (Dry mouth, unspecified) only when documentation doesn't support a more specific option: hypothermia, not associated with low environmental temperature (R68.0), nonspecific symptoms peculiar to infancy (R68.1), Clubbing of fingers (R68.3) and other general symptoms and signs (R68.8).
Don't report R68.2 together with the conditions in its Excludes1 note: dry mouth due to dehydration (E86.0) and dry mouth due to Sjögren syndrome (M35.0-).
The conditions in its Excludes2 note aren't part of R68.2, but may be coded alongside it if the patient has both: salivary gland hyposecretion (K11.7).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in Pre-MDC and MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 527.7 (disturbance of salivary secretion).
