ICD-10 code for congenital tabes

The ICD-10-CM code for congenital tabes is A50.45 (Juvenile general paresis).

Within A50.4 (late congenital neurosyphilis [juvenile neurosyphilis]), A50.45 is specifically for juvenile general paresis. Related codes cover late congenital neurosyphilis, unspecified (A50.40), late congenital syphilitic meningitis (A50.41), late congenital syphilitic encephalitis (A50.42), late congenital syphilitic polyneuropathy (A50.43), late congenital syphilitic optic nerve atrophy (A50.44) and other late congenital neurosyphilis (A50.49).

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 097 (Non-Bacterial Infection of Nervous System Except Viral Meningitis with MCC, relative weight 3.8226), DRG 098 (Non-Bacterial Infection of Nervous System Except Viral Meningitis with CC, relative weight 2.2706) and DRG 099 (Non-Bacterial Infection of Nervous System Except Viral Meningitis without CC/MCC, relative weight 1.5256), 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.
