About coding chest wall anomaly
The ICD-10-CM code for chest wall anomaly is Q67.8 (Other congenital deformities of chest). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q67.8.
Within Q67, choose Q67.8 (Other congenital deformities of chest) only when documentation doesn't support a more specific option: 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 pectus carinatum (Q67.7).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
