NHA Medical Billing & Coding (CBCS)

In ICD-10-CM, what does the abbreviation NOS in the Alphabetic Index or Tabular List indicate?

1. AThe documentation is unspecified, so an 'unspecified' code is assigned正确
2. BThe code requires an additional character to be complete
3. CTwo separate codes must be combined into one
4. DThe condition should never be coded as a primary diagnosis

为什么: NOS stands for 'not otherwise specified' and is equivalent to 'unspecified.' It is used when the medical record lacks the detail needed to assign a more specific code. Coders should query the provider when greater specificity is clinically documented but not captured.

1. A837I正确
2. B270 eligibility inquiry
3. C835 remittance
4. D837P

为什么: The 837I is the institutional claim transaction that corresponds to the paper UB-04. The 837P is the professional version for the CMS-1500, and the 835 is the electronic remittance advice.HIPAA
