About coding Halitosis

The ICD-10-CM code for Halitosis is R19.6 (Halitosis).

Within R19 (other symptoms and signs involving the digestive system and abdomen), R19.6 is specifically for Halitosis. Related codes cover intra-abdominal and pelvic swelling, mass and lump (R19.0), abnormal bowel sounds (R19.1), visible peristalsis (R19.2), abdominal rigidity (R19.3), change in bowel habit (R19.4), other fecal abnormalities (R19.5), diarrhea, unspecified (R19.7) and other specified symptoms and signs involving the digestive system and abdomen (R19.8).

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 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 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.
