Clinical InformationClinical

  • Dentinogenesis Imperfecta

    an autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth. the dentin develops poorly with low mineral content while the pulp canal is obliterated.

  • Pectus Carinatum

    a developmental anomaly characterized by abnormal anterior protrusion of the sternum and adjacent costal cartilage.

  • Arachnodactyly

    an abnormal bone development that is characterized by extra long and slender hands and fingers, such that the clenched thumb extends beyond the ulnar side of the hand. arachnodactyly can include feet and toes. arachnodactyly has been associated with several gene mutations and syndromes.

  • Acrocallosal Syndrome

    autosomal recessive syndrome characterized by hypogenesis or agenesis of corpus callosum. clinical features include mental retardation; craniofacial abnormalities; digital malformations, and growth retardation.

  • Congenital Diaphragmatic Hernia

    diaphragmatic hernia that is present at birth.

  • Dentinogenesis Imperfecta

    a congenital tooth development disorder caused by mutations in the dspp gene. the teeth are weak, discolored, and translucent.

  • Akinesia

    lack of movement.

  • Fetal Akinesia Deformation Sequence|FADS|Pena-Shokeir syndrome, Type 1

    a condition characterized by fetal akinesia and intrauterine growth restriction, that may be associated with mutation(s) in the rapsn or dok7 genes, encoding 43 kda receptor-associated protein of the synapse and protein dok-7, respectively.

  • Congenital Kyphosis

    an abnormally increased curvature of the thoracic portion of the spine that is present at the time of birth.

  • Acrocallosal Syndrome

    a rare genetic syndrome characterized by agenesis of the corpus callosum, polydactyly, mental and motor retardation.

Patient EducationClinical

Birth Defects

A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

Questions About Q74.8Overview

Is Q74.8 (Other congenital malformations of limb(s)) a billable code?

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

What MS-DRG does Q74.8 group to?

When other specified congenital malformations of limb(s) 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 Q74.8 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 malformations of limb(s) on inpatient claims.

What is the ICD-9 equivalent of Q74.8?

Under the General Equivalence Mappings, other specified congenital malformations of limb(s) converts to ICD-9-CM 755.8 (congen limb anomaly NEC). The mapping is a direct match.

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.
