Claim adjustment reason code

PR-1: Deductible amount

PR-1 means: Deductible Amount The payer applied this amount to the patient’s deductible. It is not a denial — it is the plan working as designed, and the balance is the patient’s.

Read the group code before you act on this

1 is the reason. The PR in front of it is the group code, a separate field on the remittance, and it is the one that decides who owes the money: PR means patient responsibility — the payer says the amount is owed by the patient, and it is billed to them. What the other group codes mean.

What causes PR-1?

The patient has not met their deductible for the plan year
A high-deductible plan where most early-year services fall to the patient
The deductible reset at the plan year boundary, which is not always 1 January
Services applied to a separate deductible for a specific benefit category

How do you fix a PR-1 denial?

Do not appeal this. Confirm the amount is right against the plan’s deductible and what has already been applied
Move the balance to patient responsibility and get a statement out promptly — collection rates fall sharply with age
Where the patient has other coverage, this is where the secondary claim goes
Where the deductible appears already met, that is worth a call; the payer’s accumulator can be behind

Can PR-1 be prevented?

The prevention here is financial, not clerical: check the remaining deductible during eligibility and tell the patient what they will owe before the visit. A balance discussed in advance is collected far more often than one that arrives as a surprise.

A denial like this one is the recurring cost that medical billing outsourcing is built to take off your desk — a dedicated seat working the queue instead of it waiting for whoever has a free hour.

Who does this work

A patient billing & statements seat at $1,600 per seat per month works this queue full time, during your business hours, inside your own system. Every call is logged with the payer reference number and the outcome, and every Friday you get it in writing.

Codes worked the same way

PR-1 is verified against the benefits, then billed to the patient. So are these, which is why a queue sorted by recovery route moves faster than one sorted by code number — the same person, in the same system, with the same evidence to hand, clears all of them in one pass.

PR-204 — Not covered by this plan

What leaving it costs

Working a denied claim costs $57.23 per denied claim in administrative time (source) — before any of it is recovered, and whether or not it ever is.

Payers ultimately pay roughly 90% of claims even while using an initial denial to slow payment (source), so the reason one sits is rarely that nobody knows how to work it. Put your own denial count in.

Questions

What does denial code PR-1 mean?

Deductible Amount In plain terms: The payer applied this amount to the patient’s deductible. It is not a denial — it is the plan working as designed, and the balance is the patient’s.

Is PR-1 the same as CO-1?

Same reason, different group code. The number 1 is the reason: The payer applied this amount to the patient’s deductible. It is not a denial — it is the plan working as designed, and the balance is the patient’s. The prefix says who carries the amount. PR means patient responsibility — the payer says the amount is owed by the patient, and it is billed to them. CO-1 is the same reason assigned to contractual obligation — the payer says the amount is not billable to anybody, and it is written off unless the denial itself is overturned. Read the prefix before the number: it decides whether you appeal, write off, or bill the patient.

What about the codes next to PR-1?

PR-0 and PR-2 are separate codes and this site does not yet cover them. The authoritative list is the X12 Claim Adjustment Reason Codes at x12.org/codes/claim-adjustment-reason-codes; a code is only described here once its official text, causes and fix have been written and checked.

Code descriptions are the standard X12 claim adjustment reason and remittance advice remark code text. Payer policies differ, and the payer’s own coverage policy governs any individual claim. This page is working guidance, not legal or clinical advice.
