CMS-1500 Claim Form Filler & Printer (US)

About the CMS-1500 Claim Form Filler & Printer (US)

Most claims go to payers electronically, but paper claims are still filed — by small practices without a clearinghouse, for payers that take no electronic claim for a service, and for appeals and corrected claims that have to arrive on paper. The form is the 1500 Health Insurance Claim Form, version 02/12, maintained by the National Uniform Claim Committee, and Medicare — like the other payers that scan paper claims — accepts it only on the official red-ink sheet: the scanners read the data against the drop-out red, and a photocopy is refused.

This page fills that form box by box with the NUCC instruction beside each box, checks what can be checked — NPI check digits, the order of the dates, diagnosis pointers that point at an empty line of item 21, code formats, qualifiers, the characters each box holds, item 28 as the total of 24F — and then prints the data alone, placed at the form’s own character cells, so it lands on a pre-printed sheet. On screen it shows the claim box by box, the way the record copy prints it. A calibration offset moves the whole print by hundredths of an inch for your printer, and an alignment sheet measures it. A plain record copy of the same entries is for your own file.

It does not submit electronic claims, and no CPT descriptions come with it: the AMA licenses those, so you type your own. Patients, payers and claims are kept in this browser, with an optional passcode and encrypted backups. Without a pass each claim is a free preview: its pages are images marked “not for use”, with the total charge hidden; printing, the PDFs and the claims log unlock with a Premium pass.

Common uses

• A solo practice filing a handful of paper claims a month without a clearinghouse.
• A billing company sending a corrected claim (resubmission code 7) with the payer’s original reference number.
• A therapist filing for a patient whose plan takes no electronic out-of-network claim.
• Keeping a numbered log of every claim filed, with its charges, codes and payer, for the practice’s books.

How the printing works

The 02/12 form is laid out for 10 characters to the inch and 6 lines to the inch. The page prints each entry in Courier at 12 points — exactly 10 characters an inch — at the character cell the NUCC’s grid version of the form gives for that box, on US Letter paper with no margins of its own.

For a paper claim, put the official red-ink sheet in the printer and print the data only, at 100 %: no scaling, no “fit to page”, no headers and footers. Then check a printed sheet against the form: if everything sits a little high or to the left, type the difference as the calibration offset in hundredths of an inch (positive moves the print right and down). The offset applies to the whole sheet, so one measurement fixes every box.

The form itself is never drawn by this page: payers’ scanners need the printed red-ink sheet, which you buy from a printer. The record copy is a plain listing of the same entries for your file — never send it to a payer.

What the checks look at

• NPIs (17b, 24J, 32a, 33a) with the CMS check-digit formula, and a note when the rendering NPI in 24J is the same as the billing provider’s in 33a (then 24J is left blank).
• Dates: no date of service in the future, To not before From, discharge not before admission, and a date of service from before ICD-10 took effect flagged, because it needs ICD-9-CM codes this page does not write.
• Item 21 and 24E: at least one code, the ICD-10-CM format, duplicates, and every pointer against the lines that actually hold a code — at most four pointers a line.
• Codes: the CPT or HCPCS format (five digits, or a letter and four digits), at most four modifiers, each two characters, the place of service against the CMS code set, and the EPSDT codes of 24H.
• Qualifiers: items 14, 15, 17, 17a, 24I, 32b and 33b, each against the list the NUCC allows there — and 17a’s LU only for a supervising provider.
• What fits: every box’s character count, so nothing is silently cut off when it prints.
• Money: item 28 as the sum of 24F, an amount paid larger than the total, and amounts larger than a box holds.
• The billing provider: a street address rather than a P.O. box, and the 9-digit ZIP code items 32 and 33 require.

Why no CPT descriptions

CPT codes and their descriptions are copyrighted by the American Medical Association and licensed; HCPCS Level II codes are published by CMS. This page ships no code set: you type the codes your records hold, and it checks their format only — five digits for CPT, four digits and F, T or U for the category II, III and laboratory codes, a letter and four digits for HCPCS. Item 24D on paper carries the code, not a description, so nothing is lost.

Paper or electronic?

An electronic claim (the 837P transaction) is what most payers expect, and the Administrative Simplification Compliance Act requires Medicare claims to be sent electronically unless one of its exceptions applies (Medicare Claims Processing Manual, chapter 26). Paper claims remain for those exceptions, for payers that take them, for some appeals and corrected claims, and for practices that bill a payer too rarely to set up a clearinghouse. This page makes the paper form; it does not build or send an 837.

Limitations

• It makes the paper 1500 form only: it does not submit claims, build an 837 file, check eligibility or tell you what a payer will pay.
• The form must be the official red-ink sheet for a paper claim; the record copy is for your own file.
• Codes are checked for their format, NPIs for their check digit and the place of service against the CMS list — never for whether a code is right for the service or a number is registered.
• Dates of service from before ICD-10 took effect need ICD-9-CM codes, which this page does not write.
• One claim is six service lines, as the form has; a longer claim goes on more forms.
• Claims are in US dollars on US Letter paper, and your data stays in this browser on this device.
