About coding vagina septum
The ICD-10-CM code for vagina septum is Q52.10 (Doubling of vagina, unspecified). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q52.10.
Within Q52.1, choose Q52.10 (unspecified) only when documentation doesn't support a more specific option: transverse vaginal septum (Q52.11) and longitudinal vaginal septum (Q52.12).
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 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female Reproductive 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.
