What's inside

The complete denial code playbook for DME billing

Every CO and PR denial code DME teams encounter

CO-50, CO-197, CO-16, CO-29, CO-109, CO-204, and 15+ more — all the codes that account for 85% of DME denials.

3 DME-specific root causes per code

Not generic "check documentation" advice — specific to oxygen, wheelchairs, CPAP, hospital beds, prosthetics, and wound care.

Step-by-step fix workflow for each denial

Pull the LCD, match the ICD-10, correct the CMN, submit the appeal — a numbered checklist your billing team can follow without guessing.

Sample appeal language you can paste directly

Tested appeal letter templates for each code. Drop in your claim number, patient name, and dates — the structure is already right.

Prevention checklists for each denial type

Stop the denial before submission with per-code intake and pre-bill checklists. Prevention beats recovery every time.

Denial pattern matrix by DME category

Home oxygen, power wheelchairs, CPAP, hospital beds, diabetic supplies, prosthetics, wound care — which codes hit each category hardest.
