ICD-10 code for tube disease

The ICD-10-CM code for tube disease is N83.9 (Noninflammatory disorder of ovary, fallopian tube and broad ligament, 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 N83.9.

Within N83, choose N83.9 (Noninflammatory disorder of ovary, fallopian tube and broad ligament, unspecified) only when documentation doesn't support a more specific option: follicular cyst of ovary (N83.0), corpus luteum cyst (N83.1), other and unspecified ovarian cysts (N83.2), acquired atrophy of ovary and fallopian tube (N83.3), prolapse and hernia of ovary and fallopian tube (N83.4), torsion of ovary, ovarian pedicle and fallopian tube (N83.5), Hematosalpinx (N83.6), hematoma of broad ligament (N83.7) 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.
