SNF billing (skilled nursing facility billing) is the process of submitting claims to Medicare, Medicaid, managed care plans, and private payers for the healthcare services provided to residents in a skilled nursing facility. It includes coding diagnoses on the MDS assessment, generating HIPPS codes under the PDPM payment model, completing UB-04 claim forms, managing authorizations, and following up on denials. SNF billing is more specialized than hospital or physician billing because it involves unique payer rules, assessment-driven reimbursement, and multi-payer coordination across long stays.

What Makes SNF Billing Different?
If you’ve come from hospital billing, physician billing, or even home health billing, SNF billing will feel like a different world. Here’s why:
- Payment is assessment-driven — Your reimbursement rate is determined by the MDS (Minimum Data Set) assessment, not by individual CPT codes or DRGs. The clinical team’s documentation directly determines how much you get paid.
- Residents stay for weeks or months — Unlike hospitals, where a patient is discharged in days, SNF residents may have Part A stays lasting 20, 40, or even 100 days. You’re billing monthly interim claims, not one discharge claim.
- Multiple payer sources per resident — A single resident might have Medicare Part A for the skilled stay, then transition to Medicaid for long-term care, with a Medicare Supplement paying coinsurance days 21-100. You need to know which payer is primary, when transitions happen, and how to bill each one correctly.
- Consolidated billing rules apply — During a Part A stay, your facility is responsible for billing virtually all services the resident receives. Outside providers cannot bill Medicare separately for included services.
- Regulatory changes are constant — CMS updates payment rates, code mappings, quality measures, and filing requirements annually. What was correct last year may not be correct this year.
Key Payer Sources in a SNF
Medicare Part A — Covers skilled nursing or therapy after a qualifying hospital stay. Pays the highest rates. Limited to 100 days per benefit period. Driven by PDPM and MDS assessments.
Medicare Part B — Covers physician services, some therapy, and outpatient services for residents not on a Part A stay. Billed using HCPCS/CPT codes.
Medicaid — Covers long-term custodial care for residents who qualify financially. Rates are set by each state. Often the largest volume payer by resident count.
Medicare Advantage (Managed Care) — Private plans that replace Traditional Medicare. Each plan has its own rates, authorization requirements, and appeal processes. Growing rapidly.
Private Pay/Insurance — Residents paying out-of-pocket or through long-term care insurance policies. Requires clear admission agreements and collection processes.
Core Processes for a New BOM
If you’re new to the BOM role, these are the processes you need to learn first:
- Admission financial screening — Verify insurance, confirm eligibility, establish payer source before the resident arrives
- Census management — Track every resident’s payer status, skilled days remaining, and transition dates daily
- Claim submission — Complete UB-04 forms accurately, submit within filing deadlines, and verify acceptance through DDE or your clearinghouse
- Denial management — Track denied claims, understand the reason, determine whether to appeal or correct and resubmit
- A/R follow-up — Work your aging report weekly. Claims over 30 days need attention. Claims over 90 days are problems.
- Triple Check — Review every claim against the clinical record before submission to prevent errors
- Month-end close — Reconcile census, verify all claims submitted, review credit balances, prepare reports for administration
Common Pitfalls for New BOMs
- Treating all payers the same — Medicare, Medicaid, and managed care all have different rules. What works for one doesn’t work for another.
- Not communicating with clinical staff — Your reimbursement depends on their documentation. If you don’t talk to each other, claims get denied.
- Letting the aging grow unchecked — It’s tempting to focus on new admissions and current billing. But every day a claim sits unpaid past 30 days, your facility is losing money to time value and increased denial risk.
- Not asking for help — SNF billing has a steep learning curve. There’s no shame in admitting you need training, support, or a partner to help you get up to speed.
The Bottom Line
SNF billing is complex, specialized, and high-stakes. A good Business Office Manager can make or break a facility’s financial health. If you’re new to the role and feeling overwhelmed, that’s normal — everyone starts somewhere. The key is building your knowledge systematically and not being afraid to reach out when you need guidance.
