About coding fallopian tube absence

The ICD-10-CM code for fallopian tube absence is Z90.79 (Acquired absence of other genital organ(s)). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z90.79.

Within Z90.7, choose Z90.79 (other genital organ(s)) only when documentation doesn't support a more specific option: cervix and uterus (Z90.71) and ovaries (Z90.72).

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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544), DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), 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 12 (Diseases and Disorders of the Male Reproductive System) and 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.
