About coding VDRL positive
The ICD-10-CM code for VDRL positive is A53.0 (Latent syphilis, unspecified as early or late). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on A53.0.
Within A53, choose A53.0 (Latent syphilis, unspecified as early or late) only when documentation doesn't support a more specific option: syphilis, unspecified (A53.9).
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 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
