Congenital deformities of hip

Instructional notes

Official coding guidelines

From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.

Assign Q00-QA1 codes for documented congenital anomalies or genetic disorders at any age, coding non-inherent manifestations separately and sequencing Z38 first on the birth admission.

Read Section I.C.17 (page 74)

Q65 MS-DRGs

As the principal diagnosis, all 15 billable codes under Q65 group to MS-DRG 564, 565, or 566 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

• DRG 564 Other Musculoskeletal System and Connective Tissue Diagnoses with MCC
• DRG 565 Other Musculoskeletal System and Connective Tissue Diagnoses with CC
• DRG 566 Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC
