Paper Claims Submission

Providers who are unable to submit claims electronically may submit paper claims by mail. Paper claims must be on the current and standard original claim forms and mailed to NEMS MSO. NEMS MSO does not accept faxed copies of claims. Paper claims submission requirements are described below:

  • The most current and standard CMS-1500 (HCFA-1500) or CMS-1450 (UB-04) claim form must be used. The form needs to be in Flint OCR Red, J6983 (or exact match) ink. NEMS MSO does not supply claim forms to providers. Providers should purchase these forms from a supplier of their choice.
  • Although a copy of the claims forms can be downloaded, photocopies of the claims form cannot be used for submission of claims since a copy may not accurately replicate the scale and Optical Character Recognition (OCR) color of the form.
  • Medical coding, or the claims information, must be typed in black ink with 10-point or 12-point Times New Roman font on the required original red and white version to ensure clean acceptance and processing.
  • Claims submitted on black and white, handwritten, or nonstandard forms will be rejected, and a letter will be sent to the provider indicating the reason for rejection. These claims will not be returned to the provider.
  • To reduce document handling time, providers must not use highlights, italics, bold text, or staples for multiple page submissions.

CMS-1500 and CMS-1450 completion and coding instructions are available on the Centers for Medicare & Medicaid Services (CMS) website at www.cms.gov.

  • Claims received from a provider’s clearinghouse are acknowledged directly to the clearinghouse in the same manner and time frames noted above.

NEMS MSO follows the Timely Claims Payment rule according to 42 CFR Ch. IV, HHS, §447.45 and Title 28 CCR § 1300.71:

  • 90% of clean provider claims must be paid, contested, or denied within 30 calendar days of the first received date.
  • 95% of claims must be paid, contested, or denied within 45 business days.
  • If claims are paid beyond 45 business days, the claim will automatically include interest per AB1455 for the period of time that the payment is late.
  • 99% of all clean provider claims must be paid within 90 days of the date of receipt.
  • The timely payment period is the same for both electronic and paper claims.

Balance Billing

Balance billing is strictly prohibited by NEMS policy, Health Plans, and state and federal law.

Providers are prohibited from billing covered members for fees and surcharges above and beyond a member’s copayment and coinsurance responsibilities for services covered under a member’s benefit program, or for claims for such services denied by NEMS MSO. Providers are also prohibited from initiating, or threatening to initiate, a collection action against a member for non-payment of a claim for covered services. Participating providers agree to accept reimbursement from NEMS for services as payment in full and final satisfactory, except for applicable copayments, coinsurance, or deductibles.

Billing Medicare–Medi-Cal Members Prohibited

Providers are prohibited from collecting Medicare Parts A and B deductibles, coinsurance, or copayments from members enrolled in the qualified Medicare beneficiaries (QMB) program, which exempts members from Medicare cost-sharing liability. For members enrolled in the Health Net Medicare Advantage program and assigned to NEMS PPG, providers can either accept the NEMS MSO payment as payment in full or bill the state for applicable Medicare cost-sharing for members who are eligible for both Medicare and Medicaid. This prohibition applies to all Medicare Advantage (MA) providers, not only those that accept Medicaid. In addition, balance billing restrictions apply regardless of whether the state Medicaid agency is liable to pay the full Medicare cost-sharing amounts.

Providers have the right to a fast, fair, and cost-effective dispute resolution process for disputes regarding a claim payment, denial, billing determinations, and contract issues. NEMS MSO will ensure timely acknowledgement and resolution of provider disputes.

NEMS MSO will not request that providers resubmit claim or supporting documentation that was previously submitted to NEMS MSO as part of the claim’s adjudication process unless NEMS MSO returned the information to the provider.

Provider Dispute Resolution (PDR) request is a written notice to North East Medical Services (NEMS) MSO appealing a claim that has been paid, adjusted, contested, or denied; or seeking resolution of a billing determination; or disputing a request for reimbursement of an overpayment of a claim.

NEMS MSO will not discriminate or retaliate against a provider due to a provider’s use of the Provider Dispute process. A provider dispute is processed without charge to the provider; however, NEMS MSO has no obligation to reimburse the provider for any costs incurred during the provider dispute process.

NOTE: Claims denied due to provider’s claim submission error or omission (e.g., missing modifier, incorrect CPT / ICD-10, or place of service code, missing EOB/EOMB or requested invoice, etc.) DO NOT qualify for the Provider Dispute Resolution Mechanism and should be resubmitted within the claim’s submission timeframe as a corrected claim. Please include a brief explanation of the error either noted on the claim or as an attachment.
