ICD-10 code for uterus malformation

The ICD-10-CM code for uterus malformation is Q51.9 (Congenital malformation of uterus and cervix, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q51.9.

Within Q51, choose Q51.9 (Congenital malformation of uterus and cervix, unspecified) only when documentation doesn't support a more specific option: agenesis and aplasia of uterus (Q51.0), doubling of uterus with doubling of cervix and vagina (Q51.1), other doubling of uterus (Q51.2), Bicornate uterus (Q51.3), Unicornate uterus (Q51.4), agenesis and aplasia of cervix (Q51.5), Embryonic cyst of cervix (Q51.6), congenital fistulae between uterus and digestive and urinary tracts (Q51.7) and 1 more.

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.
