Question:
What is the proper ICD-9 code for anatrial mass? Massachusetts Subscriber
Answer:
If "mass" is the only information you have, 429.89 (
Other ill-defined heart diseases; other) may be your best option.
Watch out:
You should not choose a neoplasm code for a "'mass,' unless otherwise stated," according to an ICD-9 note with 239.x (
Neoplasms of unspecified nature).
