0:55
0:48Rejected claims. Wrong form locators. Cash sitting in the clearinghouse.
Most SNF claim rejections never reach the payer. They die in the clearinghouse on an ASC X12 5010 syntax error, a missing condition code, or a type-of-bill that does not match the patient's stay phase. Every kicked claim is a 5 to 14 day delay before cash arrives.
Form locator and TOB mistakes
UB-04 has 81 form locators. SNF type-of-bill codes (211 admission, 212 interim, 214 discharge, 217 replacement) trip up generic billers. One wrong digit and the claim bounces.
ASC X12 5010 syntax errors
837i EDI transactions follow strict X12 5010 segment and loop rules. Missing CLM or SBR segments, malformed REF qualifiers, or NPI placement errors kick claims back as 999 acknowledgment rejects.
HIPPS placement and revenue codes
SNF Part A HIPPS code belongs in FL 44. Revenue codes 0022 for PDPM HIPPS lines need to match the MDS assessment. Miss the link and the claim posts at the default rate, not the case-mix rate.

What is UB-04 / 837i claims submission ?
UB-04 / 837i claims submission is the institutional billing workflow for SNF Part A, home health 30-day periods, hospice, and inpatient hospital claims. The UB-04 (also called CMS-1450) is the paper form with 81 form locators. The 837i is its electronic counterpart, transmitted as an ASC X12 5010 EDI transaction through a clearinghouse to Medicare, Medicaid, and Medicare Advantage payers. Both carry the same data: provider NPI, patient demographics, type-of-bill, revenue codes, HCPCS, HIPPS, condition codes, occurrence codes, value codes, and the line-level charges that sum to the total claim amount.
What your UB-04 / 837i claims team handles, day to day
Eight production tasks every claim build hits before submission. Your in-house business office focuses on resident admissions, the corporate billing lead reviews KPIs, and your billing pod runs the queue.
Form locator build (FL 1 to 81)
Populates every required UB-04 form locator. Provider info, patient demographics, type-of-bill, NPI placement, value and condition codes.
Type-of-bill assignment
211 admission, 212 interim, 213 second interim, 214 discharge, 217 replacement, and 218 void. Maps to the resident's stay phase.
Revenue and value code work
Revenue codes for room and board, ancillary, therapy. Value codes for Medicare days, coinsurance, and lifetime reserve where applicable.
Occurrence and condition codes
Occurrence codes for accident date, transfer, hospice election. Condition codes for outpatient billing, NCD denials, MSP coordination.
HIPPS code placement
Pulls HIPPS from the 5-day MDS for SNF. Places in FL 44. Confirms revenue code 0022 lines match. Watches for IPA reassessments.
ASC X12 5010 scrubbing
Runs claim through clearinghouse 5010 edits. Resolves CLM, SBR, REF, NM1 segment errors before submission to Medicare or MA plan.
Submission and 277CA work
Submits via Availity, Change Healthcare, or direct payer. Works 277CA acknowledgments and 999 functional acks every morning.
Rejection rework and resubmission
Fixes rejected claims same-day. Re-bills under the same control number where allowed. Documents root cause for QAPI feedback.
UB-04 trained billers, not generic offshore coders
Most outsourcing firms offer general medical billers and call them "institutional claim experts." We do not. Our claims specialists pass a UB-04 form locator assessment and an 837i ASC X12 5010 syntax test before they ever build a live SNF or home health claim in your facility.
Form locator and X12 tested
Every biller passes a written assessment on UB-04 form locators 1 through 81, 837i loop and segment structure under ASC X12 5010, and HIPPS placement for SNF Part A before placement on a live account.
Stacked compliance posture
HIPAA + SOC 2 Type II + ISO 27001 + HITRUST. Plus alignment with 42 CFR 424 conditions of payment and 45 CFR 164.514 de-identification rules. All four certificates available on request.

Frequently asked questions
What is the difference between UB-04 and 837i?
The UB-04 (CMS-1450) is the paper institutional claim form with 81 form locators. The 837i is its electronic counterpart, transmitted as an ASC X12 5010 EDI transaction set through a clearinghouse such as Availity or Change Healthcare. They carry the same data fields but in different formats. Most Medicare, Medicaid, and MA plans require 837i for production billing.
What type-of-bill (TOB) codes are used for SNF Part A?
SNF TOB codes are three-digit identifiers in FL 4. The first two digits are facility type (21 for SNF inpatient). The third digit is frequency: 211 admission through discharge, 212 interim first, 213 interim continuing, 214 interim last, 217 replacement, 218 void.
Where does the HIPPS code go on the UB-04?
The SNF HIPPS code goes in form locator 44 on the revenue code 0022 line. The HIPPS code is a five-character code derived from the PDPM five-component case-mix calculation. The MDS assessment date drives the HIPPS, and the assessment must be transmitted to iQIES before the claim is built.
What is ASC X12 5010 and why does it matter?
ASC X12 5010 is the HIPAA-mandated EDI standard for the 837i institutional claim transaction. It defines loop and segment structure: ISA and GS envelopes, ST and SE transaction sets, NM1 names, REF reference IDs, CLM claim segment, SBR subscriber, SV2 service line. Every Medicare and MA plan accepts only 5010-compliant 837i files.
What are condition codes and when do they go on a UB-04?
Condition codes occupy form locators 18 through 28 (up to 11 codes). Common SNF and home health codes include 07 (treatment of nonterminal condition for hospice patient), 21 (billing for denial notice), 30 (qualifying clinical trials), and 77 (provider accepts payment by primary payer as payment in full).
How do you handle FL form locators 1 through 81?
Our billers work a documented form locator checklist. FL 1 provider, FL 4 TOB, FL 6 statement-covers period, FL 8 patient name, FL 12 admission date, FL 17 patient status, FL 18 to 28 condition codes, FL 31 to 34 occurrence codes, FL 39 to 41 value codes, FL 42 revenue codes, FL 44 HIPPS, FL 50 payer, FL 56 NPI, FL 67 principal diagnosis, FL 76 attending provider.
How does pricing work across multiple claims billers and facilities?
Per claims biller FTE, per week. Per-skill pricing for UB-04 / 837i claims, AR follow-up, denial management, and payment posting roles. No setup fees. $399 Standard, $349 Volume (3 or more), $299 Enterprise (10 or more). Add or remove billers by the week.
What is included in the 2-Week Risk-Free Pilot?
Two weeks of live UB-04 and 837i claim build and submission running in parallel with your business office. Full reporting on clean-claim rate, 277CA rejection rate, average submission lag, and TOB mix. No setup fee. No penalty if you cancel before day 14.
