About Q71.02
Q71.02 is the ICD-10-CM diagnosis code for congenital complete absence of left upper limb. It belongs to category Q71 (reduction defects of upper limb), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Q71.0 (congenital complete absence of upper limb), Q71.02 is specifically for congenital complete absence of left upper limb. Related codes cover unspecified upper limb (Q71.00), right upper limb (Q71.01) and bilateral (Q71.03).
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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 755.21 (transverse deficiency of upper limb).
