About coding carinatum congenital pectus
The ICD-10-CM code for carinatum congenital pectus is Q67.7 (Pectus carinatum). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q67.7.
Within Q67 (congenital musculoskeletal deformities of head, face, spine and chest), Q67.7 is specifically for pectus carinatum. Related codes cover congenital facial asymmetry (Q67.0), congenital compression facies (Q67.1), Dolichocephaly (Q67.2), Plagiocephaly (Q67.3), other congenital deformities of skull, face and jaw (Q67.4), congenital deformity of spine (Q67.5), pectus excavatum (Q67.6) and other congenital deformities of chest (Q67.8).
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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
