ICD-10 code for Bizarre appearance

The ICD-10-CM code for Bizarre appearance is R46.1 (Bizarre personal appearance).

Within R46 (symptoms and signs involving appearance and behavior), R46.1 is specifically for Bizarre personal appearance. Related codes cover Very low level of personal hygiene (R46.0), Strange and inexplicable behavior (R46.2), overactivity (R46.3), Slowness and poor responsiveness (R46.4), Suspiciousness and marked evasiveness (R46.5), Undue concern and preoccupation with stressful events (R46.6), Verbosity and circumstantial detail obscuring reason for contact (R46.7) and other symptoms and signs involving appearance and behavior (R46.8).

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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
