National Drug Code (NDC)

without comments

The NDC is a universal number that identifies a drug.

A National Drug Code (NDC) number is a unique number assigned to a product that identifies the manufacturer, drug, packaging size, and type. It appears on all drug labels

The National Drug Code (NDC) is a universal product code used as an identifier for every unique commercially available drug product for human use in the USA.

Developed by the Food and Drug Administration (FDA) in 1969.

FDA used the Drug Listing Act of 1972 to create a current list of all drugs manufactured, prepared, propagated, compounded, or processed by a drug establishment registered under the Federal Food, Drug, and Cosmetic Act.

The NDC system was originally established by Medicare as an essential part of an outpatient drug reimbursement program and as a method to identify drugs during commercial distribution.

NDC is used for

  • NDC is used for institutional billing.
  • The NDC is used to identify the manufacturer and the medicine
  • NDC  is used as identifier for drugs intended for human use.
  • The NDC is used to report prescribed drugs and biologics to enhance claim reporting .

NDC is used by

  • NDC numbers are used throughout the drug supply chain. Users extend from
    pharmaceutical firms,
    distribution system,
    medical community,
    insurance industry, and

NDC can help to reduce or prevent medication errors, by assisting in the safe dispensing of medications. Outpatient pharmacists may use the NDC system to avoid confusion with look-alike/sound-alike drugs.

NDC help in the computerization of medication-related processes in health settings:

  • Supply chain
  • Ordering
  • Identifying
  • Decision support
  • Effectiveness evaluation

NDC Code is :

  • Up to 11 digits in length
  • Separated by hyphens (-) into three segments
  • Complete NDC is formatted 5-4-2, for a total of 11 digits:  12345-1234-12
  • The NDC is found on the drug container (that is vial, bottle, tube).
  • The first five digits identify the manufacturer of the drug and are assigned by the Food and Drug Administration. The remaining digits are assigned by the manufacturer and identify the specific product and package size.

NDC Code is comprised of 3-segments :

  1. The first segment is the “labeler” code.
    The first five digits identify the manufacturer of the drug and are assigned by the Food and Drug Administration.
    4-5 characters.
  2. The second segment is the “product” code.
    It identifies the strength, dosage form and formulation.
    3-4 characters.
  3. The third segment is the “package” code.
    identifies package size.
    1-2 characters

Time and Attendance Software

without comments

Time and attendance software is a computerized information system used by organizations to effectively and efficiently manage employees work time.  It collects employee time data and enters the information into a database. The collected data is reviewed and approved by a supervisor so it can be used for payroll processing and custom reports.

The System:

  • Accurately captures and monitors real-time employee data;
  • Enforces work rules and regulations;
  • Eliminates buddy-punching;
  • Provides payroll with accurate information (interfacing vs. integrating); Transfers the hours worked, overtime, department, holidays, sick time, and vacation time;
  • Enables employees to view job-related time and employee information, including: schedules, time cards, accrued or used benefits, and exception history.
  • Collects exceptions defined within the payroll rule assigned to each employee;
  • Enables supervisors to view exceptions by employee in a calendar format;
  • Provide comprehensive employee statistics, from badge listings to overtime calculations;
  • Schedules can handle organization’s full range of conditions;
  • Schedules conform to relevant government requirements


  • Accurate Tracking. A time and attendance system automates the process of tracking employees as they check in and out for work leading to accurate time data for each employee and fewer payroll processing errors (effectiveness).
  • Increased Efficiency. Time and attendance systems enable managers to monitor employee hours in real-time, track hours, unauthorized overtime, and create detailed reports about individual employees. Benefits include better schedule and workforce management and less human error in the payroll cycle.
  • Cost Control. Time and attendance systems can reduce payroll costs significantly. Better labor tracking can eliminate thousands in over payments and significantly lessen the work load of the payroll department.
  • Employees Satisfaction. Employees are satisfied that they are being paid accurately.
  • Audit Trail. Time records available when companies are audited, providing a detailed trail of employee exceptions and supervisor approvals.
  • Regulatory compliance. An effective time and attendance management software is a powerful tool in ensuring that the organization is complying with regulations pertaining to human resources management.

Are Smartphones Bad for your Educational Performance?

with 4,727 comments

At the beginning of the biostatistics course I am teaching this semester I collected data on 20 different variables from registered students  (n=150) to use for practice purposes during class meetings and exercises. Click to see the SPSS output of this t test

Today, doing an independent samples t test, we found that students who do not own a smartphone (mean CGPA=3.31, n=22) are out performing their peers who do have smartphones (mean CGPA=3.02, n=118). The difference between the groups was statistically significant , with a p-value of 0.038.

The class is made of undergraduate students studying biotechnology, nutrition, laboratory, medical diagnostics, nursing , health administration, environmental health and physiotherapy. The mean age of students in this class is 20.55 years with sd=3.2 years. Ninety five percent of the class are female.

Students, What explanation/s do you have for this finding?

Healthcare Common Procedure Coding System

with 5,007 comments

The Healthcare Common Procedure Coding System (HCPCS) is a set of health care procedure codes. Commonly pronounced Hick-Picks.

The Healthcare Common Procedure Coding System (HCPCS) was established in 1978 to provide a standardized coding system for describing the specific items and services provided in the delivery of health care.

  • HCPCS is the standard HIPAA code set for reporting supplies, orthotic and prosthetic devices, and durable medical equipment. In combination with the Current Procedure Terminology (CPT) codes, it is also used to report physician and other health care services.
  • HCPCS is one of the formats in which drugs and biologics may be coded for reimbursement and other reporting for non-retail pharmacy settings. (NDC is an alternative. The HIPAA regulations do not at present designate a single standard for this purpose.)
  • Health insurance plans process billions of claims every year. HCPCS codes were developed to help ensure that claims could be processed in a consistent and simplified way. HCPCS codes are divided into three subsystems: level I, level II and level III, each designated for a specific purpose.
  1. HCPCS Codes – Level ILevel I HCPCS codes are made up of CPT-4 codes (a numeric coding system devised by the American Medical Association). Health care professionals use this notation to identify services and procedures, for which they bill insurance programs. Level I HCPCS codes consist of 5 numeric digits.
  2. HCPCS Codes – Level II (Alpha-numeric codes)
    Level II HCPCS codes identify products, supplies, materials and services which are not included in the CPT-4 code, such as ambulance services, prosthetics, medical equipment and supplies when used outside a medical office. Level II HCPCS codes are also called alpha-numeric codes because they consist of one letter followed by 4 numeric digits.
  3. HCPCS – Level III (Local Codes)
    Level III HCPCS codes are developed by Medicaid State Agencies, Medicare contractors and private insurers for use in specific programs and jusrisdictions. HCPCS Level III codes are also called local codes. These codes allow insurers to electronically process claims for new services for which a level I or level II code has not yet been established.

Diagnosis Related Groups (DRGs)

with 4,018 comments

Diagnosis Related Groups (DRGs): A classification system that groups patients according to principal diagnosis, presence of a surgical procedure, age, presence or absence of significant comorbidities or complications, and other relevant criteria.

Diagnosis-related group (DRG) is a U.S. system to group and classify hospital cases into different groups (more than 500) on the basis of diagnosis/diagnoses, procedures, age, sex, discharge status, and the presence of complications or comorbidities.

A DRG is based upon the principal ICD-9-CM diagnosis code, ICD-9-CM surgical procedure code, age of patient, and expected length of stay in the hospital that will be reimbursed, independently of the charges that the hospital may have incurred

Cases within each category are similar clinically and are expected to use the same level of hospital resources

This system was developed for Medicare use as part of the prospective payment system.

DRGs have been used in the US since 1983 to determine how much Medicare pays participating hospitals. A DRG is a payment category that is used to classify patients, especially Medicare patients, for the purpose of reimbursing hospitals for each case in a given category with a fixed fee regardless of the actual costs incurred.

Current Procedural Terminology

with 6,470 comments

A medical code set, maintained and copyrighted by the AMA, that has been selected for use under HIPAA for non-institutional and non-dental professional transactions.

  • CPT was developed by the American Medical Association (AMA) in the 1960s, and soon became part of the standard code set for Medicare and Medicaid. In subsequent decades it was adopted by private insurance carriers and managed care companies, and became the de facto standard.
  • The Healthcare Common Procedure Coding System (HCPCS) incorporates CPT codes as part of its system for classifying services for reimbursement.

    • Health Care Claim: Institutional
      This transaction is used to electronically transmit a hospital claim used for billing payers for hospital claims including inpatient (S), outpatient (M), and Diagnosis Related Grouping (DRG) (R) claims. Washington Medicaid uses this transaction for home health claims as well.
    • Health Care Claim: Dental
      This transaction is used to electronically transmit a dental claim used for billing payers for dental related services.
  2. Health care payment and remittance advice (إشعار بالدفع)
    This transaction may be used by a health plan
    – to make a payment to a financial institution for a health care provider (sending payment only),
    – to send an explanation of benefits or a remittance advice directly to a health care provider (sending data only), or
    – to make payment and send an explanation of benefits remittance advice to a health care provider via a financial institution (sending both payment and data).Remittance Advice: is used to report any payment or denial of claims submitted to health plans for payment.
  3. Coordination of benefits
    This transaction can be used to transmit health care claims and billing payment information between health plans with different payment responsibilities where coordination of benefits is required or between health plans and regulatory agencies to monitor the rendering, billing, and/or payment of health care services within a specific health care/insurance industry segment.
  4. Health claim status
    This transaction may be used by health care providers and recipients of health care products or services (or their authorized agents) to request the status of a health care claim or encounter from a health plan.
  5. Enrollment and disenrollment in a health plan
    This transaction is used to establish communication between the sponsor of a health benefit and the health plan. It provides enrollment data, such as subscriber and dependents, employer information, and health care provider information. The sponsor is the backer of the coverage, benefit or product. A sponsor can be an employer, union, government agency, association, or insurance company. The health plan refers to an entity that pays claims, administers the insurance product or benefit, or both.
  6. Inquiry of Eligibility for a health plan
    This transaction is used to inquire about the eligibility, coverage, or benefits associated with a benefit plan, employer, plan sponsor, subscriber, or a dependent under the subscriber’s policy.It also can be used to communicate information about or changes to eligibility, coverage, or benefits from information sources (such as insurers, sponsors, and health plans) to information receivers (such as physicians, hospitals, third party administrators, and government agencies).is the transmission of an inquiry from a health care provider to a health plan, or from one health plan to another health plan, to obtain any of the following information about a benefit plan for an enrollee:
    – Eligibility to receive health care under the health plan.
    – Coverage of health care under the health plan.
    – Benefits associated with the benefit plan.
  7. Health plan premium payments
    This transaction is used by, for example, employers, employees, unions, and associations to make and keep track of payments of health plan premiums to their health insurers.
  8. Referral certification and authorization
    This transaction is used to transmit health care service referral information between health care providers, health care providers furnishing services, and health plans.It can also be used to obtain authorization for certain health care services from a health plan.

Personal Health Record (PHR)

with 6,416 comments

What is a PHR?
An electronic record of health-related information on an individual that conforms to nationally recognized interoperability standards and that can be drawn from multiple sources while being managed, shared, and controlled by the individual.

A personal health record or PHR is typically a health record (a collection of important information) that is initiated and maintained by an individual. It is different than patient  health record, which includes  information about one’s health compiled and maintained by healthcare providers. An ideal PHR would provide a complete and accurate summary of the health history of an individual by gathering data from many sources and making this information accessible online to anyone who has the authorization to view the information.

The information contained in a PHR will come from different healthcare providers (doctor, dentist, physio-therapists, …), but it is maintained and managed by the individual

PHR allows patients to store and access their health information electronically. PHR helps an individual plan and document any care or treatment he/she is receiving. PHRs have the potential to give individuals more control over their health information — collecting, using, and sharing it as they see fit.

Uses and Benefits of PHR:

  • Collect and store patient information;
  • Collect and store information from a patient’s health care provider;
  • Convert clinical information into more easily understood language;
  • Describe to patients ways to improve their health based on their information;
  • Make it possible for patients to take action on their information;
  • Track appointments, vaccinations, and other services;
  • Improve the quality of care you they receive;
  • Provide timely information when receiving emergency care and ensure access to vital health information;
  • Reduce costs by eliminating duplicate tests

In general, PHRs contain the following types of health information:

  • allergies and adverse drug reactions
  • chronic diseases
  • family history
  • illnesses and hospitalizations
  • imaging reports (e.g. x-ray)
  • immunization records
  • laboratory test results
  • medications and dosing including over the counter medications and herbal remedies
  • surgeries and other procedures
  • vaccinations
  • and Observations of Daily Living (ODLs)

Epidemiological Studies

with 5,715 comments

Case Report (case series)
A case report is a descriptive study of a single individual (case report) or small group (case series) in which the possibility of an association between an observed effect and a specific exposure is based on detailed clinical evaluations and histories of the individual(s). They are most likely to be useful when the disease is rare and when it is caused exclusively or almost exclusively by a single kind of exposure. Case reports (or case series) may be first to provide clues in identifying a new disease or adverse health effect from an exposure.

Case Control Studies
Case-control is a type of epidemiological study design. In a case-control study, individuals with a disease are matched with people who do not have the disease (the ‘controls’). Further data are then collected on those individuals and the groups are compared to find out if other characteristics  are also different between the two groups. Case-control design is typically used for retrospective studies, but can also be applied to prospective studies as well.

Cohort Study
A cohort study is a  study design used in epidemiology. It first identifies individuals on the basis of their exposure to a disease causing factor, such as exposure to a toxic chemical or other factor that may be implicated in a disease. It begins by taking a group of people who are free from the disease of interest. The epidemiologist then follows the individuals over a period of time and observes new occurrences of the disease. It is called a cohort because a cohort of individuals refers to a group of individuals who are similar with respect to exposure to a certain disease causing factor.

Authentication is the procedure of determining whether someone is, in fact, who he/she declares to be. Authentication is generally required to access secure data or enter a secure area.

  • In information systems, user Authentication refers to the process of determining user’s identity as well as determining what a user is authorized to access {Who and What}.
  • Authentication typically involves the use of a user name and password; certificate, PIN, digital signature and other information that can be used to validate the identity over a network.
  • User authentication ensures that the right information gets to the right person.
  • Example: Hospital admission clerk accesses the information system using her username and password, which allows her access to the admission module of the system, but not other parts of the system.
