Medicare Secondary Payer Manual (Pub. 100-05), Ch. 5 § 40.3.1
GHP Denies Payment for Primary Benefits
40.3.1 - GHP Denies Payment for Primary Benefits
(Rev. 11550; Issued: 08-12-22; Effective: 10-13-22; Implementation:10-13-22)
Where a GHP has denied the claim because the plan provides only secondary coverage, the A/B
MAC and the DME MAC denies the claim for Medicare primary benefits. If a provider bills a GHP
and the plan refuses to pay primary benefits because it claims that its benefits are secondary to
Medicare's, the A/B MAC and the DME MAC does not pay conditional benefits. Instead, it suspends
the claim and sends an ECRS request to the MSP Contractor for development.
If the A/B MAC and DME MAC pays primary Medicare benefits and later learns that the
beneficiary is appealing the GHP denial, it treats the payment as a conditional primary payment.
The A/B MAC (Part A) should instruct its provider that, if a GHP has denied its claim for primary
benefits, the provider must annotate Item 84 "Remarks" of the Medicare claim form with the reason
for the denial and enter occurrence code 24 and the date of denial in Items 32 to 35. The A/B MAC
(Part A) annotates its records with the reason for the denial to avoid the need for any future recovery
efforts.
The A/B MAC (Part B) and DME MAC processing a claim with similar GHP involvement would
send the beneficiary a denial letter including similar information and state that if the GHP does not
pay the full charge, then the beneficiary must submit a claim for secondary benefits including a copy
of the GHP's explanation of benefits. If the physician, or supplier accepted assignment, the A/B MAC
and DME MAC notifies the physician/supplier and the beneficiary that the beneficiary may not be
charged more than the Medicare deductible and coinsurance amounts and charges for noncovered
services. (Services that are or could have been paid for by the GHP are not considered "noncovered.")
Any denial notice must include appropriate appeals information. The A/B MAC and the DME MAC
advises the beneficiary to consult with his or her employer and/or the state insurance commissioner
or other official having jurisdiction (such as the U.S. Department of Labor) if he or she believes the
GHP should have paid for the services. The A/B MAC and the DME MAC also advises the claimant
of the private right of legal action to collect double damages. (See Chapter 2, §40.1.)
