Where an Underpayment Either Gets Caught or Gets Quietly Written Off as Normal

Payment posting is the step where an adjudicated claim's actual outcome gets recorded, whether that arrives as an 835 electronic remittance advice or a paper explanation of benefits, applying the specific CARC and often RARC codes attached to every line item, and reconciling what was actually paid against what was billed and what the payer contract actually specifies. Done correctly, this is where the revenue cycle either confirms a claim resolved properly or catches that it didn't.

Here's the risk that matters most and shows up least. A payment that posts below the contracted rate, when the remaining balance simply gets written off as a routine contractual adjustment without anyone verifying it against the actual fee schedule, closes the account exactly as if everything had been resolved correctly. The claim now reads as paid in full. Nothing about it looks unusual, nothing flags it for review, and a genuine, recoverable underpayment quietly becomes money that will very likely never be looked at again, not because it was written off deliberately, but because it was written off by default.

MedCloudMD's payment posting is built around catching that specific gap. We use automated posting for speed on clean, matching remittances, and we route anything that doesn't match expectations, an unexpected adjustment code, a payment below the contracted rate, a denial embedded in an otherwise-paid remittance, to a genuine human exception review rather than posting it unchecked. Zero-pay remittances get posted with their denial codes intact, and cash that can't be immediately matched to an account gets actively researched rather than left sitting as an unresolved balance.
