Coding Errors/Modifiers

1. Why is my claim for an Evaluation and Management (E/M) visit denied as bundled into another procedure, when I have billed the 25 modifier on the claim, which is needed since a surgery was performed on the same day as the E/M visit?
  The E/M service may be in the global period of another procedure. If the E/M service is unrelated to the previous procedure and significant, separately identifiable from the procedure performed on the same day both Modifier 24 and 25 may be necessary. The 24 modifier is appropriate if the E/M service is unrelated and during the postoperative period of the major surgery. The 25 modifier is also needed to identify that the E/M services is significant, separately identifiable from the minor surgery/procedure performed on the same day. In addition, the minor surgery procedure code may need a 79 modifier to indicate the procedure is not related to the major surgery.

CMS 1500 Claim Form Item

2. How do I report an NPI on a CMS-1500 claim form when the provider is a sole practitioner?
  A sole practitioner should enter their NPI in box 33-a. This is different from a provider who is a member of a group. Providers who are members of a group must enter their individual NPI in box 24-j, and the group NPI in box 33-a

Appeals Process/Rights

3. If Medicare denies a service, do I have any appeal rights and, if so, what is the process to file an appeal?
  Part B providers and beneficiaries have 120 days to file a request for a redetermination from the date of receipt of the remittance notice or Medicare Summary Notice (MSN). This is the first level of appeal conducted by Medicare contractors, and it must be done in writing. If a claim was returned as unprocessable, a new claim should be submitted with additional or corrected information. A redetermination cannot be performed on unprocessable claims.

Provider Information

4. Why was my claim returned indicating an incorrect primary identifier?
  Reference to the primary identifier usually means that you are billing something incorrectly regarding the billing/individual provider (number), in CMS 1500 claim form box 33-a, or box 24-j. This would indicate the Provider Transaction Access Number (PTAN) or NPI of the group or the individual performing provider.

Medicare Secondary Payer (MSP)

5. My claim denied stating that the patient has other primary insurance; however, when I checked eligibility on the IVR it stated that Medicare is primary. Why is my claim being denied?
  Often times an MSP record is updated by the Coordination of Benefits Contractor (COBC) after a claim has been submitted and denied by Medicare. If you have verified that the records are updated to reflect Medicare as primary on the date of the denied service, then a new claim can be resubmitted.

Payment Explanation/Calculation

6. Why was the reimbursement for the claim I submitted reduced?
  There are several reasons whereby reimbursement levels can be reduced. For example, payments can be reduced based upon multiple surgery guidelines, when a secondary surgical procedure is billed with a "51" modifier. For surgical procedures which are appropriately billed as secondary, the reimbursement level is reduced to 50 percent of what that procedure would approve were it to be performed by itself.

Similarly, an Evaluation and Management Code (E/M) billed the day of or the day before surgery is usually considered part of the surgical package, and reimbursement for it may be included in the reimbursement for the surgery itself. The Medicare Physician Fee Schedule Database (MPFSDB) offers additional information regarding this process.

Payment Explanation/Calculation

4. Why was my claim paid at a lower amount for surgery than what the fee schedule indicates is appropriate?
  Based on the combination of codes you are billing, the reduction was most likely based upon multiple surgery guidelines. These guidelines reduce Medicare's reimbursement for secondary and additional procedures in most instances where multiple surgical procedures are performed during the same operative session.
