About coding congenital chordee
The ICD-10-CM code for congenital chordee is Q54.4 (Congenital chordee).
Within Q54 (hypospadias), Q54.4 is specifically for congenital chordee. Related codes cover balanic (Q54.0), penile (Q54.1), penoscrotal (Q54.2), perineal (Q54.3), other hypospadias (Q54.8) and unspecified (Q54.9).
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.
