Coding tips for R19.7
Diarrhea NOS, when no cause is documented.
What to document
- Code the cause when it’s documented, such as A08.4 (viral intestinal infection) or A09 (infectious gastroenteritis and colitis, unspecified).
- If the provider documents functional diarrhea, use K59.1.
Watch for
- Neonatal diarrhea is P78.3 and psychogenic diarrhea F45.8, not R19.7.
- Once a related diagnosis is confirmed, don’t add R19.7 for diarrhea that routinely comes with it.
