About coding pseudohermaphroditism
The ICD-10-CM code for pseudohermaphroditism is Q56.3 (Pseudohermaphroditism, unspecified). The official index lists 13 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q56.3.
Within Q56, choose Q56.3 (Pseudohermaphroditism, unspecified) only when documentation doesn't support a more specific option: Hermaphroditism, not elsewhere classified (Q56.0), male pseudohermaphroditism, not elsewhere classified (Q56.1), female pseudohermaphroditism, not elsewhere classified (Q56.2) and indeterminate sex, unspecified (Q56.4).
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.
