ICD-9 CM Diagnosis Codes that Support Medical Necessity

It is not enough to link the procedure code to a correct, payable ICD-9-CM diagnosis code. The diagnosis or clinical suspicion must be present for the procedure to be paid. Below are diagnosis codes that support medical necessity.

Reasons for Denial

Services with diagnoses other than those listed above and services where the submitted diagnosis is not an active medical problem which would impede the safe performance of the procedure will be considered not medically necessary or reasonable.

Non-Covered ICD-9-CM Codes

Use of any ICD-9-CM diagnosis code not included in the "ICD-9-CM Diagnosis Codes that Support Medical Necessity" section of this policy will be cause for denial of claims.

Coding Guidelines

1.  

The diagnosis code (ICD-9-CM) should indicate the co-existing medical condition requiring the presence of the anesthesiologist/anesthetist, rather than the gastrointestinal condition for which the endoscopy was done.

2.  

For those requiring the presence of an anesthesiologist/anesthetist because of massive upper gastrointestinal bleeding, use the appropriate ICD-9-CM diagnosis code for gastrointestinal hemorrhage.

3.  

When upper and lower endoscopy procedures are performed at the same setting, and a physician other than the performing surgeon administers anesthesia for both procedures, he/she should bill the base charge only once plus the time for both procedures
