Questions About Q74.0Overview

Is Q74.0 (Other congenital malformations of limb(s)) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other congenital malformations of upper limb(s), including shoulder girdle on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does Q74.0 group to?

When other congenital malformations of upper limb(s), including shoulder girdle 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 Q74.0 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 congenital malformations of upper limb(s), including shoulder girdle on inpatient claims.

What is the ICD-9 equivalent of Q74.0?

Under the General Equivalence Mappings, other congenital malformations of upper limb(s), including shoulder girdle converts to ICD-9-CM 755.53 (radioulnar synostosis), 755.54 (Madelung's deformity), and 755.56 (accessory carpal bones). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
