About coding chordee
The ICD-10-CM code for chordee is N48.89 (Other specified disorders of penis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N48.89.
Within N48.8, choose N48.89 (Other specified disorders of penis) only when documentation doesn't support a more specific option: thrombosis of superficial vein of penis (N48.81), acquired torsion of penis (N48.82) and acquired buried penis (N48.83).
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) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male 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.
