Colonoscopy

A colonoscopy is a medical procedure that allows your doctor to examine your colon (the large intestine). It utilizes a thin, flexible tube with a tiny camera on the end, which is inserted through the rectum. This procedure can help identify issues such as polyps, inflammation, or early signs of cancer. It's usually recommended for people over 50 or those with specific risk factors.

Hernia repair (minimally invasive)

Hernia repair is a surgery to fix a hernia - a condition where an organ pushes through an opening in the muscle or tissue that holds it in place. Minimally invasive hernia repair involves small incisions, a tiny camera, and special surgical tools. This method often leads to quicker recovery, less pain, and reduced scarring compared to traditional surgery.

NPI Validation Check Digit Calculation


The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.

Start with the original NPI number, the last digit is the check digit and is not used in the calculation.
1184687592
Step 1: Double the value of the alternate digits, beginning with the rightmost digit.
2116412814518
Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.
2 + 1 + 1 + 6 + 4 + 1 + 2 + 8 + 1 + 4 + 5 + 1 + 8 + 24 = 68
Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.
70 - 68 = 22

The NPI number 1184687592 is valid because the calculated check digit 2 using the Luhn validation algorithm matches the last digit of the original NPI number.
