Clinical Classification

Clinical Information

  • Congenital Alopecia

    a congenital condition characterized by the absence of hair on the scalp or entire body. the lack of hair is rarely absolute and is usually accompanied by incompletely grown, lanugo-like hair. it affects males twice as much as females and a familial tendency is common.
  • ABCA12 wt Allele|ABC12|ARCI4A|ARCI4B|ATP Binding Cassette Subfamily A Member 12 wt Allele|ATP-Binding Cassette, Sub-Family A (ABC1), Member 12 Gene|ATP-Binding Cassette, Subfamily A, Member 12 Gene|DKFZP434G232|ICR2B|Ichthyosis Congenita II, Lamellar Ichthyosis B Gene|LI2

    human abca12 wild-type allele is located in the vicinity of 2q35 and is approximately 207 kb in length. this allele, which encodes glucosylceramide transporter abca12 protein, plays a role in both the membrane localization of glucosylceramide and other lipids in lamellar granules and in cholesterol transport. mutation of the gene is associated with autosomal recessive congenital ichthyosis (arci) types 4a and 4b (harlequin).
  • Lamellar Ichthyosis

    a very rare, autosomal recessive inherited skin disorder present at birth. it is characterized by the presence of a transparent membrane encasing the newborn. this membrane sheds in about two weeks after birth to reveal generalized scaling and skin erythema.
  • Acroosteolysis

    a condition that is characterized by degeneration of the distal phalanges.

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)

Q84.0 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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
