About coding oral phase dysphagia
The ICD-10-CM code for oral phase dysphagia is R13.11 (Dysphagia, oral phase).
Within R13.1 (dysphagia), R13.11 is specifically for dysphagia, oral phase. Related codes cover unspecified (R13.10), oropharyngeal phase (R13.12), pharyngeal phase (R13.13), pharyngoesophageal phase (R13.14) and other dysphagia (R13.19).
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 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
