Questions About Q68.8Overview

Is Q68.8 (Other congenital musculoskeletal deformities) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified congenital musculoskeletal deformities on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does Q68.8 group to?

When other specified congenital musculoskeletal deformities is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 565, 566, with relative weights from 0.7493 to 1.5436 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q68.8 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other specified congenital musculoskeletal deformities on inpatient claims.

What is the ICD-9 equivalent of Q68.8?

Under the General Equivalence Mappings, other specified congenital musculoskeletal deformities converts to ICD-9-CM 755.51 (cong deformity-clavicle), 755.52 (cong elevation-scapula), and 756.9 (musculoskel anom NEC/NOS). The mapping is approximate, so confirm the match fits the documentation.
