Reader Question:

Add a 5th Digit to Your Rhinorrhea Dx

Question: What diagnosis should I use for rhinorrhea?

Answer: Effective Oct. 1, 2006, you should report "rhinorrhea" with ICD-9 code 478.19 (Other diseases of nasal cavity and sinuses). This unspecified code describes "other diseases of nasal cavity and sinuses" including "rhinolith," according to the code's inclusion entry in the 2007 ICD-9-CM Manual.

Code 478.19 is a new code for ICD-9 2007. You previously would have coded rhinorrhea as 478.1. This code now requires a fifth digit of 1 for "nasal mucositis (ulcerative)" or 9 for "other diseases of nasal cavity and sinuses."

Tool: You can use ICD-9's tabular list to locate the appropriate code for rhinorrhea. On page 251 in "Volume 2" of the 2007 ICD-9-CM Physician Manual, you will find "Rhinorrhea 478.19."
