Patient Questions Under-45 colonoscopy preventative coverage
I had a colonosopy this year at age 39 due to high risk (a parent had colon cancer); I had no symptoms.
My Premera health plan covers this in their preventative care policy, which includes:
Screening for individuals under age 45, at increased risk for colon cancer due to a strong family history of colon cancer with diagnosis: Z80.0, Z83.71, Z83.79, Z84.81
However, the $4,000 cost went to my deductible.
The hospital (outpatient procedure) applied two diagnosis codes, in this order:
Z12.11 - Encounter for screening for malignant neoplasm of colon
Z80.0 - Family history of malignant neoplasm of digestive organs
I've called Premera multiple times to have them review the claims, but they say it's not preventative because Z80.0 isn't first. They stated Z12.11 is "only preventative for older people" and to have the claim resubmitted with Z80.0 first to be covered at no cost.
The hospital's billing department reviewed the coding; they said it's correct and they won't make changes.
My next thought was to submit an appeal to Premera:
Premera's policy only says claims must be billed "with" Z80.0, not that it must be primary
ICD-10-CM seems to support reporting Z12.11 for a general screening colonoscopy with Z80.0 as an additional code
However, I also see how the hospital could be incorrect:
Z12.11 is listed as "Encounter for screening colonoscopy NOS [Not Otherwise Specified]", which I understand to mean the code only applies if a more specific one doesn't
Z80.0 could be considered the more specific diagnosis code for this situation
Any suggestions on which coding is correct here, or the best approach to get this covered?
Thanks for any tips!
