Clinical InformationClinical

  • Polydactyly

    a congenital anomaly of the hand or foot, marked by the presence of supernumerary digits.

  • Short Rib-Polydactyly Syndrome

    a syndrome inherited as an autosomal recessive trait and incompatible with life. the main features are narrow thorax, short ribs, scapular and pelvic dysplasia, and polydactyly.

  • Smith-Lemli-Opitz Syndrome

    an autosomal recessive disorder of cholesterol metabolism. it is caused by a deficiency of 7-dehydrocholesterol reductase, the enzyme that converts 7-dehydrocholesterol to cholesterol, leading to an abnormally low plasma cholesterol. this syndrome is characterized by multiple congenital abnormalities, growth deficiency, and intellectual disability.

Questions About Q69.9Overview

Is Q69.9 (Polydactyly) a billable code?

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

What MS-DRG does Q69.9 group to?

When polydactyly, unspecified 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 Q69.9 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 polydactyly, unspecified on inpatient claims.

What is the ICD-9 equivalent of Q69.9?

Under the General Equivalence Mappings, polydactyly, unspecified converts to ICD-9-CM 755.00 (polydactyly NOS). The mapping is approximate, so confirm the match fits the documentation.
