ICD-10 code for Tuberous sclerosis

The ICD-10-CM code for Tuberous sclerosis is Q85.1 (Tuberous sclerosis).

Within Q85 (phakomatoses, not elsewhere classified), Q85.1 is specifically for Tuberous sclerosis. Related codes cover neurofibromatosis (nonmalignant) (Q85.0), other phakomatoses, not elsewhere classified (Q85.8) and Phakomatosis, unspecified (Q85.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.
