Clinical Classification

Clinical Information

  • Endocardial Fibroelastosis

    a condition characterized by the thickening of endocardium due to proliferation of fibrous and elastic tissue, usually in the left ventricle leading to impaired cardiac function (cardiomyopathy, restrictive). it is most commonly seen in young children and rarely in adults. it is often associated with congenital heart anomalies (heart defects congenital;) infection; or gene mutation. defects in the tafazzin protein, encoded by taz gene, result in a form of autosomal dominant familial endocardial fibroelastosis.
  • Congenital Cataract

    cataract that is present at birth.
  • Microcornea

    a congenital abnormality characterized by an abnormally small cornea. the horizontal corneal diameter is less than 10mm or less than 9mm in newborns. it is associated with an increased risk of glaucoma.
  • Psoriasiform Dermatitis

    a chronic, sporadic, acquired pruritic non-infectious skin condition characterized by one or more well defined inflamed (pink or red) patches or plaques of varying size.
  • Endocardial Fibroelastosis

    a rare disorder characterized by diffuse thickening of the endocardium. it presents with unexplained heart failure.
  • TAFAZZIN wt Allele|BTHS|Barth Syndrome Gene|CMD3A|Cardiomyopathy, Dilated 3A (X-Linked) Gene|EFE|EFE2|Endocardial Fibroelastosis 2 Gene|G4.5|LVNCX|TAZ|TAZ1|Tafazzin, Phospholipid-Lysophospholipid Transacylase wt Allele|Taz1

    human tafazzin wild-type allele is located in the vicinity of xq28 and is approximately 10 kb in length. this allele, which encodes tafazzin protein, plays a role in phospholipid metabolism, including cardiolipin remodeling. mutations in the gene are associated with barth syndrome, dilated cardiomyopathy (dcm), hypertrophic dcm, endocardial fibroelastosis and left ventricular noncompaction.

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)

Q12.0 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.

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 Q12.0 to ICD-9-CM

  • ICD-9-CM Code: 743.30 - Congenital cataract NOS
    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


Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include:

  • Refractive errors
  • Cataracts - clouded lenses
  • Optic nerve disorders, including glaucoma
  • Retinal disorders - problems with the nerve layer at the back of the eye
  • Macular degeneration - a disease that destroys sharp, central vision
  • Diabetic eye problems
  • Conjunctivitis - an infection also known as pink eye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.

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.
