## TL;DR

Reconciling 837P professional claims to 835 remittance means matching each submitted claim (by patient control number and claim id) to the payer's adjudication: paid amount, adjustments with CARC/RARC codes, and denials. Build the match on the claim identifiers both files carry, then bucket the variances: paid in full, paid with adjustments (read the CARC codes for why), and denied (appeal or correct and resubmit). Track denial codes by frequency; the top codes usually point to fixable front-end issues like eligibility or coding errors. This reconciliation is the core of revenue-cycle visibility.

## The query

```text
healthcare 837P claims vs 835 remittance: reconciliation for agents
```

## Use this when

- Tying submitted claims to payer remittance
- Reading CARC/RARC adjustment codes
- Healthcare revenue cycle reconciliation

## Not for

- Institutional 837I claims (different format and rules)
- Eligibility verification itself (upstream process)

## Steps

1. Match 835 remittance lines to 837P claims on claim identifiers.
   Expected output: Every submitted claim has a remittance outcome.
2. Bucket outcomes: paid in full, paid with adjustments, denied.
   Expected output: The population is triaged.
3. Read CARC/RARC codes on adjustments to learn the payer's reason.
   Expected output: Each adjustment is understood, not just noted.
4. Work denials: correct and resubmit, or appeal with documentation.
   Expected output: Denied revenue is recovered where possible.
5. Trend denial codes to fix front-end causes (eligibility, coding).
   Expected output: The denial rate falls over time.

## Variant phrasings

### 837P 835 reconciliation

### healthcare claims remittance matching

### CARC RARC codes explained

## Root cause

The 837P and 835 are the two halves of the claim lifecycle: the 837P is what you asked for, the 835 is what the payer decided, linked by shared claim identifiers. Reconciliation works because both files speak the same id language; the CARC/RARC codes are the payer's explanation layer on top.

## Edge cases

- Secondary payer (COB) claims need the primary 835 before the secondary 837 goes out
- Timely filing limits make stale unreconciled claims expire; age your inventory
