In ICD-10-CM, what does the abbreviation NOS in the Alphabetic Index or Tabular List indicate?
- AThe documentation is unspecified, so an 'unspecified' code is assignedCorrecta
- BThe code requires an additional character to be complete
- CTwo separate codes must be combined into one
- DThe condition should never be coded as a primary diagnosis
Por qué: 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.
