Adhere to ICD-10 Coding Guidelines Now [avoid payment disruptions]


Adhere to ICD-10 Coding Guidelines Now [avoid payment disruptions]

October 1st, 2016 marks the end of the grace period allotted by CMS and AMA to facilitate smooth ICD-10 implementation. During the grace period, insurances processed claims even if they were wrongly coded, just as long as the codes belonged to the broader family of correct codes. However, such claims will not be paid after the grace period. It now becomes crucial for medical practices to strictly adhere to ICD-10 coding guidelines to avoid payment disruptions.

Here are a few guidelines for screening and surveillance colonoscopy.

Difference between screening and surveillance colonoscopies
Screening is a test provided to a patient in the absence of signs or symptoms. A screening colonoscopy is a service performed on an asymptomatic person for the purpose of testing the presence of colorectal cancer or colorectal polyps.
A surveillance colonoscopy can be performed at varying ages and intervals based on the patient’s personal history of colon cancer, polyps, and/or gastrointestinal disease. For example, patients with a history of colon polyps are not recommended for a screening colonoscopy, but for a surveillance colonoscopy.


Coding guidelines
ICD-10 guidelines clearly demarcate between coding for screening and surveillance.
