Q52.122 ICD-10-CM Code: Longitudinal vaginal septum, obstructing, left side
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.
- MS-DRG 742 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITH CC/MCC (MDC 13)
- MS-DRG 743 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITHOUT CC/MCC (MDC 13)
- MS-DRG 760 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITH CC/MCC (MDC 13)
- MS-DRG 761 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITHOUT CC/MCC (MDC 13)
A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Potential MS-DRG Relationships (FY2026)
Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.
Named in the grouper logic of 4 MS-DRGs: DRG 742 (MDC 13), DRG 743 (MDC 13), DRG 760 (MDC 13), DRG 761 (MDC 13).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
