About coding Slurred
The ICD-10-CM code for Slurred is R47.81 (Slurred speech).
Within R47.8 (other speech disturbances), R47.81 is specifically for Slurred speech. Related codes cover fluency disorder in conditions classified elsewhere (R47.82) and other speech disturbances (R47.89).
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 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous 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.
