Payment Posting

Medical Payment Posting Services

Niyutsa Technologies posts payments against the claims they belong to and checks each one against your contracted reimbursement rate, not just against the amount the remittance says was paid. A partial payment that gets posted and closed without that comparison is revenue that quietly disappears.

Payment Posting — Niyutsa Technologies revenue cycle management services

The problem

Why this step decides whether the claim gets paid

Payment posting is often treated as a data-entry step, but it is the point where an underpayment either gets caught or gets written off by default. If posting staff post whatever the remittance shows without comparing it to the contract, the practice absorbs every payer's rounding, bundling, and fee-schedule error silently.

What we do

Payment Posting capabilities

Electronic remittance posting

Payments posted from the HIPAA X12 835 electronic remittance advice, matched to the correct claim and line item.

Contracted-rate reconciliation

Each payment compared against the expected reimbursement under your payer contract, not accepted at face value.

Underpayment flagging

Discrepancies between expected and actual payment flagged for follow-up rather than adjusted off automatically.

Patient responsibility transfer

Copay, coinsurance, and deductible amounts transferred to patient balances accurately based on the remittance's own breakdown.

Denial and adjustment code review

Claim adjustment reason codes and remittance advice remark codes reviewed so a denial embedded in a partial payment is not missed.

Manual posting for paper EOBs

Payers that still issue paper explanation of benefits are posted manually with the same reconciliation standard as electronic remittances.

How it works

Our payment posting process

Step 1

Receive remittance

Electronic 835 files or paper EOBs are received from the payer or clearinghouse.

Step 2

Match to claims

Each payment line is matched to the specific claim and service line it corresponds to.

Step 3

Compare to contract

The paid amount is checked against the expected contracted rate for that service.

Step 4

Post the payment

The payment is posted, with any patient responsibility separated out.

Step 5

Flag discrepancies

Underpayments or unexpected adjustments are flagged rather than silently accepted.

Step 6

Route for follow-up

Flagged discrepancies are handed to AR follow-up for appeal or correction.

Answers

Payment Posting questions answered

Payment posting is recording payments from payers and patients against the specific claims they belong to, reconciling what was actually paid against what was expected under the payer contract, and moving any remaining balance to the correct next step, whether that is patient billing or an appeal.

A paid claim is not the same as a correctly paid claim. Payers can underpay due to fee schedule errors, bundling, or incorrect contract application, and if the payment is posted without comparison to the contracted rate, that gap is never recovered.

X12 835 is the HIPAA-standard electronic remittance advice transaction. It is the payer's electronic explanation of how a claim was adjudicated and paid, and it is what most electronic payment posting is built from.

The discrepancy is flagged rather than posted and closed. Depending on the size and pattern, it is either routed for an appeal or added to a tracked list of underpayments for that payer, so a pattern of systematic underpayment becomes visible instead of being absorbed one claim at a time.

Pecos Enrollment covers the complete preparation, submission, and follow-through required for this specific credentialing function — from initial document collection through final payer approval and effective-date confirmation. Our team manages every step so nothing is left for the provider or practice to track manually.

Timelines vary by payer and provider type, but most engagements involving pecos enrollment reach completion in 60 to 120 days. We provide a specific timeline estimate during intake based on your exact payer mix and current credentialing status.

Pecos Enrollment is available as part of our standard credentialing service and can also be engaged on its own for practices that need this specific function addressed. Contact us for a scope-specific quote based on your current situation.

Pecos Enrollment is managed by our dedicated credentialing specialists who handle this function daily across hundreds of provider engagements, ensuring consistent, accurate submissions and fast turnaround on any payer follow-up requests.

PECOS (Provider Enrollment, Chain, and Ownership System) is used to enroll in Medicare. NPPES (National Plan and Provider Enumeration System) is used to obtain and manage an NPI number. Every Medicare provider needs both — an NPI first, then a PECOS enrollment. NPPES is administered by CMS separately from PECOS and has its own login credentials.

Paper CMS-855 forms can still be filed by mail, but processing times for paper applications are significantly longer than for PECOS online submissions — typically 90 to 120 days versus 60 to 90 days for PECOS. Paper filings also have higher error rates because they lack the built-in validation of the online system. We recommend PECOS online for all applications where possible.

CMS notifies providers of PECOS approval through the PECOS system itself and by mailed letter to the correspondence address on file. We monitor application status daily and notify you immediately when your PTAN is issued, so you do not have to wait for the mailed confirmation to begin billing preparation.

MAC development letters carry a 30-day response window. If you do not respond within 30 days, the MAC will deny the application and you must restart the enrollment from the beginning. This is why our same-business-day response practice is critical — we ensure development letters never lapse.

Adding a new practice location requires a PECOS update through a change of information filing. Failure to update PECOS when practice locations change causes Medicare claims for services at the unregistered location to be denied. We handle location changes and other PECOS updates as part of our ongoing maintenance program.

Getting credentialed with Medicare requires a complete CAQH ProView profile (for payers that use CAQH), a formal application submitted through Medicare's provider enrollment process, and verification of your license, board certification, malpractice history, and work history. Niyutsa Technologies manages this entire process, including any Medicare-specific application requirements.

Medicare credentialing typically takes 45 to 120 days from application submission to approval, depending on current processing volume and whether your CAQH profile is complete and attested at the time of submission. We track every Medicare application and follow up proactively rather than waiting for status inquiries.

Panel status with Medicare varies by specialty and geographic market and can change without public notice. We verify current panel status for Medicare as part of every credentialing engagement, and where a panel is closed, we prepare a formal panel reopening request documenting patient access needs.

Yes. We manage ongoing Medicare re-credentialing on the standard cycle Medicare requires, along with CAQH attestation, demographic updates, and any development letters Medicare issues during the recredentialing review.

Medicare fee-for-service (Traditional Medicare) enrollment is through PECOS and administered by CMS. It covers all fee-for-service claims from enrolled providers. Medicare Advantage plans are operated by private insurers who contract with CMS to offer Medicare benefits — each plan requires its own separate credentialing application. Enrolling in fee-for-service Medicare does not make you in-network with any Medicare Advantage plan, and vice versa.

Medicare provider enrollment is completed through the PECOS online system at pecos.cms.hhs.gov. The application type depends on your provider category — individual physicians use Form 855I, group practices use Form 855B, and reassignment of benefits is handled through Form 855R or the equivalent PECOS electronic process. We manage the entire PECOS application on your behalf, including identity proofing and electronic signature coordination.

A Medicare opt-out affidavit is a formal declaration that a physician or practitioner has chosen to be excluded from Medicare. Opted-out providers can enter private contracts with Medicare beneficiaries for services that Medicare would otherwise cover, outside the standard Medicare payment system. Opt-out is typically considered by concierge or direct primary care physicians, certain psychiatrists, and providers who prefer not to be bound by Medicare's fee schedule. Opt-out must be renewed every 2 years.

CMS requires all enrolled providers to complete revalidation on a cycle of 3 to 5 years depending on provider type. CMS notifies providers of upcoming revalidation deadlines approximately 6 months in advance through the PECOS system and by mail to the correspondence address on file. Revalidation processing time is similar to initial enrollment — 60 to 90 days. We monitor revalidation deadlines for all active clients and begin the process 120 days before the deadline to ensure continuous enrollment.

Medicare enrollment is provider-specific, not practice-specific, so the provider's enrollment follows them. However, when a provider changes practices, several PECOS updates are required: updating the practice location and billing entity, filing new reassignment of benefits with the new group, and removing reassignment from the prior group. These changes must be filed promptly to ensure claims from the new practice location route correctly and prior-practice claims close properly.

Frequently asked questions

PECOS (Provider Enrollment, Chain, and Ownership System) is the CMS online portal for Medicare enrollment applications. It replaces paper Form 855 for most provider types and provides real-time validation, status tracking, and electronic signature capabilities. We manage the entire PECOS application process on your behalf.

Medicare enrollment through PECOS typically takes 60 to 90 days from application submission to PTAN issuance. Processing speed depends on the regional MAC jurisdiction, application completeness, and whether development letters are issued. Our same-day development letter response keeps timelines at the shorter end.

A PTAN (Provider Transaction Access Number) is your unique Medicare billing identifier issued after enrollment approval. PTANs are issued by your regional MAC and confirmed via the PECOS system. You receive your PTAN at the end of the enrollment process, typically 60 to 90 days after application submission.

Generally no. CMS does not allow retroactive billing for services rendered before the Medicare enrollment effective date in most circumstances. Starting the PECOS application 90 to 120 days before a provider start date is the most effective way to avoid billing gaps.

CMS requires all enrolled providers to revalidate enrollment every 3 to 5 years. Revalidation confirms your credentials and practice information remain current. Missing a revalidation deadline results in automatic deactivation of billing privileges with no retroactive billing allowed during the deactivation period.
