Look to Screening LCDs for High-Risk Clues

Watch out: Medicare carriers may differ on some ICD-9 codes

When you are coding for your Medicare patients' colorectal cancer screenings, be sure to append the appropriate diagnosis codes -- especially when you report the high-risk screening.

Why? All Medicare carriers will have a set list of diagnoses that they will accept when you report G0105 (Colorectal cancer screening; colonoscopy on individual at high risk).

The problem is the lists might not be consistent from carrier to carrier.

Solve the Problem Easily

No sweat: All you have to do is contact your local Medicare carrier, or check out its local coverage determination (LCD), and you'll be able to find out what conditions your payer allows for G0105.

Also, check out this partial list of ICD-9 codes that prove a patient is at high risk for colorectal cancer from Wheatlands Administrative Services (a Medicare carrier for Kansas, Nebraska and parts of Missouri). Check your local carrier for a similar list.
