Medical Billing Lead, Denials and Appeals, A. Datum Medical Group
Dear Jennifer Lindgren,
I'm applying for the Medical Billing Lead role on A. Datum Medical Group's denials and appeals team. I'm a Certified Professional Biller with 6 years in multi-specialty and orthopedic billing, and at Lakecrest Physician Group I submit 1,200+ professional claims a week for a 40-provider group.
Much of my best work starts with the denial report. I added claim scrubber edits for our top 10 denial reasons, and our first-pass clean claim rate went from 89% to 96%. Fewer bad claims going out leaves more time to work the ones that come back, and in 2025 I recovered $310K in underpaid claims through denials and appeals with Medicare, Medicaid and commercial payers.
I also keep old balances from piling up. Over 18 months, A/R over 90 days fell from 24% to 13% of total receivables. I post ERA and manual payments and reconcile daily deposits in Epic. Earlier, at Bluff Street Orthopedics, I checked CPT, ICD-10-CM and HCPCS codes and modifiers against documentation for 6 surgeons and handled prior authorizations for surgeries and imaging.
I'd welcome the chance to talk about your denial trends and where I could help first. Thank you for considering my application.
Sincerely,
Andrea Kowalski

01
Lead with clean claims and A/R
Clean claim rate, denial rate and aged A/R are the numbers revenue cycle managers look for first.
02
Explain how you found the problem
One sentence on how you traced denials to their cause shows judgment, not just volume.
03
Name payers and systems
Mention the payer types and practice management or EHR systems you've worked in, especially if the posting lists them.

Something else? support@launch-cv.com
Should I mention my billing certification?
Yes. If you hold a CPB, CPC or similar credential, name it in the first paragraph.
How do I show results without sharing patient information?
Use rates and totals, such as clean claim rate or aged A/R, and leave out patient names, account details and anything else covered by HIPAA.
