Clinical Information

• A behavior disorder in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity.
• A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (from dsm-iv)
• A disorder characterized by a marked pattern of inattention and/or hyperactivity-impulsivity that is inconsistent with developmental level and clearly interferes with functioning in at least two settings (e.g. At home and at school). At least some of the symptoms must be present before the age of 7 years.
• Is it hard for your child to sit still? does your child act without thinking first? does your child start but not finish things? if so, your child may have attention deficit hyperactivity disorder (adhd). Nearly everyone shows some of these behaviors at times, but adhd lasts more than 6 months and causes problems in school, at home and in social situations. Adhd is more common in boys than girls. It affects 3-5 percent of all american children.the main features of adhd are
  • inattention
  • hyperactivity
  • impulsivity

  no one knows exactly what causes adhd. It sometimes runs in families, so genetics may be a factor. There may also be environmental factors.a complete evaluation by a trained professional is the only way to know for sure if your child has adhd. Treatment may include medicine to control symptoms, therapy, or both. Structure at home and at school is important. Parent training may also help.

ICD-10: A Brief Synopsis

For disease reporting, the US utilizes its own national variant of ICD-10 called the ICD-10 Clinical Modification (ICD-10-CM). A procedural classification called ICD-10 Procedure Coding System (ICD-10-PCS) has also been developed for capturing inpatient procedures. The ICD-10-CM and ICD-10-PCS were developed by the Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS). There are over 70,000 ICD-10-PCS procedure codes and over 69,000 ICD-10-CM diagnosis codes, compared to about 3,800 procedure codes and roughly 14,000 diagnosis codes found in the previous ICD-9-CM.

The expansion of healthcare delivery systems and changes in global health trends prompted a need for codes with improved clinical accuracy and specificity. The alphanumeric coding in ICD-10 is an improvement from ICD-9 which had a limited number of codes and a restrictive structure. Early concerns in the implementation of ICD-10 included the cost and the availability of resources for training healthcare workers and professional coders.

There was much controversy when the transition from the ICD-9-CM to the ICD-10-CM was first announced in the US. Many providers were concerned about the vast number of codes being added, the complexity of the new coding system, and the costs associated with the transition. The Centers for Medicare and Medicaid Services (CMS) weighed these concerns against the benefits of having more accurate data collection, clearer documentation of diagnoses and procedures, and more accurate claims processing. CMS decided the financial and public health cost associated with continuing to use the ICD-9-CM was too high and mandated the switch to ICD-10-CM.
