Clinical Classification

Clinical Information

  • Facial Asymmetry

    congenital or acquired asymmetry of the face.
  • Choanal Atresia

    a congenital abnormality that is characterized by a blocked choanae, the opening between the nose and the nasopharynx. blockage can be unilateral or bilateral; bony or membranous.
  • Hypertelorism

    abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.
  • Exocrine Pancreatic Insufficiency

    a malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (lipase; proteases; and amylase) by the exocrine pancreas into the duodenum. this condition is often associated with cystic fibrosis and with chronic pancreatitis.
  • Osteopetrosis

    excessive formation of dense trabecular bone leading to pathological fractures; osteitis; splenomegaly with infarct; anemia; and extramedullary hemopoiesis (hematopoiesis, extramedullary).
  • Osteosclerosis

    an abnormal hardening or increased density of bone tissue.
  • Platybasia

    a developmental deformity of the occipital bone and upper end of the cervical spine, in which the latter appears to have pushed the floor of the occipital bone upward. (dorland, 27th ed)
  • Facial Asymmetry

    a finding indicating the absence of balanced proportions between parts of the face.
  • Osteosclerosis

    abnormally high bone density.
  • CDAN1 Gene|CDAN1|CDAN1|Congenital Dyserythropoietic Anemia, Type I Gene

    this gene may be involved in nuclear membrane maintenance.

    human cdan1 wild-type allele is located in the vicinity of 15q15.2 and is approximately 14 kb in length. this allele, which encodes codanin-1 protein, may play a role in the maintenance of the nuclear envelope. mutation of the gene is associated with congenital dyserythropoietic anemia type i.
  • Congenital Dyserythropoietic Anemia

    a rare group of disorders that result in anemia that is caused by ineffective erythropoiesis, which is associated with multinuclear erythroblasts, and which may present in childhood. the most common mutations are in the cdan1 and sec23b genes.
  • Congenital Dyserythropoietic Anemia Type II|CDA II|CDAN2|HEMPAS|Hereditary Erythroblastic Multinuclearity with Positive Acidified-Serum Test|SEC23B-CDG

    an autosomal recessive subtype of congenital dyserythropoietic anemia caused by mutation(s) in the sec23b gene, encoding protein transport protein sec23b.
  • Congenital Dyserythropoietic Anemia Type IV|CDAN4

    an autosomal dominant sub-type of congenital dyserythropoietic anemia caused by mutation(s) in the klf1 gene, encoding krueppel-like factor 1.
  • SEC23B wt Allele|CDA-II|CDAII|CDAN2|Congenital Dyserythropoietic Anemia, Type II Gene|HEMPAS|RP11-379J5.1|Sec23 Homolog B (S. cerevisiae) wt Allele

    human sec23b wild-type allele is located in the vicinity of 20p11.23 and is approximately 54 kb in length. this allele, which encodes protein transport protein sec23b, is involved in the transport of vesicles from the endoplasmic reticulum to the golgi. mutation of the gene is associated with congenital dyserythropoietic anemia type ii.
  • Frontal Bossing

    a skeletal deformity characterized by an unusually prominent forehead. causes include acromegaly, hurler syndrome, silver-russell syndrome, and thalassemia major.

Tabular List of Diseases and Injuries

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Absence of skull bone, congenital
  • Congenital deformity of forehead
  • Platybasia

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Present on Admission (POA)

Q75.8 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

CMS POA Indicator Options and Definitions

POA IndicatorReason for CodeCMS will pay the CC/MCC DRG?
YDiagnosis was present at time of inpatient admission.YES
NDiagnosis was not present at time of inpatient admission.NO
UDocumentation insufficient to determine if the condition was present at the time of inpatient admission.NO
WClinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission.YES
1Unreported/Not used - Exempt from POA reporting. NO

Convert Q75.8 to ICD-9-CM

  • ICD-9-CM Code: 756.0 - Anomal skull/face bones
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Craniofacial Abnormalities

Craniofacial is a medical term that relates to the bones of the skull and face. Craniofacial abnormalities are birth defects of the face or head. Some, like cleft lip and palate, are among the most common of all birth defects. Others are very rare. Most of them affect how a person's face or head looks. These conditions may also affect other parts of the body.

Treatment depends on the type of problem. Plastic and reconstructive surgery may help the person's appearance.
