End-stage renal disease (ESRD) billing requirements

Below is an overview of the most common billing requirements; it is not meant to be all-inclusive. There may be other ESRD-related services that are billed using codes that may not be reflected here.

Billing requirements

Submit your monthly ESRD services on a 72X type of bill (TOB).

TOBs acceptable codes for Medicare are:

TOB	Definition
721	Admit through discharge claim. This code is used for a bill encompassing an entire course of outpatient treatment for which the provider expects payment from the payer.
722	Interim - first claim. This code is used for the first of an expected series of payment bills for the same course of treatment.
723	Interim - continuing claim. This code is used when a payment bill for the same course of treatment is submitted, and further bills are expected to be submitted later.
724	Interim - last claim. This code is used for a payment bill which is the last of a series for this course of treatment. The “Through” date of this bill (FL 6) is the discharge date for this course of treatment.
727	Replacement of prior claim. This code is used when the provider wants to correct (other than late charges) a previously submitted bill. The previously submitted bill needs to be resubmitted in its entirety, changing only the items that need correction. This is the code used for the corrected or “new” bill.
728	Void/cancel of a prior claim. This code indicates this bill is a cancel-only adjustment of an incorrect bill previously submitted. Cancel-only adjustments should be used only in cases of incorrect provider identification numbers, incorrect Medicare beneficiary identifier, duplicate payments, and some Office of Inspector General recoveries. For incorrect provider numbers or Medicare beneficiary identifier, a corrected bill is also submitted using a code 721.

Statement covers from and through dates

The beginning and ending service dates of the period should be included on one bill. Note: ESRD services are subject to the monthly billing requirements for repetitive services.

The statement covers 'from' and 'through' dates must reflect the first day dialysis began in the billing month through the last day of dialysis in the billing month.

• Example: 03/03/24-03/27/24, not 03/01/24-03/31/24

Line-item detail billing is required for ESRD claims. Each service must be submitted on a separate line with the appropriate line-item date of service. The Medicare standard systems perform line-item date of service compare for ESRD claims with statement billing periods overlapping the statement billing period of another processed claim. This prevents monthly claims from receiving overlapping edits based on the statement billing period dates but rather, only when the ESRD claim has a line item that duplicates another processed claim.

Diagnosis codes

Report a principal diagnosis and any other diagnosis codes for co-morbidity conditions (if applicable).

The lists of the comorbidity categories and diagnosis codes are found on the CMS website in the ESRD prospective payment system (PPS) patient-level adjustments site under downloads:

• ESRD PPS Comorbidity Categories and Diagnostic Codes external link

Condition codes

ESRD claims must have one dialysis condition code per claim to describe the dialysis setting. If two dialysis settings are used during the month, then two claims must be filed. It is recommended to submit each claim for the full range of dates of service that are applicable to each type of dialysis through each last day of dialysis that was performed in the billing month.

Billing and coding overview

ESRD facilities furnishing dialysis treatments in-facility are paid for up to three treatments per week. ESRD facilities treating patients at home regardless of modality receive payment for three hemodialysis (HD) equivalent treatments per week. Payment for additional treatments may be considered when there is medical justification for more than three weekly treatments.

Hemodialysis: Payment based on standard of three treatments per week.

Peritoneal Dialysis (CAPD and CCPD): Payment based on hemodialysis equivalent sessions.

For home patients undergoing peritoneal dialysis (PD), the number of days of PD regardless of the number of dialysate exchanges performed each day, is converted to HD-equivalent sessions. This is accomplished by dividing the number of days of PD by seven and multiplying the result by three.

Intermittent Peritoneal Dialysis (IPD): Payment based on hemodialysis equivalent sessions.

Hemofiltration: Alternative to peritoneal dialysis and hemodialysis. payment based on hemodialysis equivalent sessions.

* Regardless of dialysis modality or treatment setting, payments for additional treatments may be made when they are medically justified. The A/B MAC reviews the medical justification and is responsible for making the decision on the appropriateness of the extra treatment.

Revenue code	Frequency	Condition code	Value code	Monthly limit
0634- EPO<10,000 or 0635- EPO>10,000	Three times per week	N/A	48 and/or 49	13 times in 30 days/ 14 times in 31 days
0636- Darbepoetin Alfa (DPO) (Aranesp)	N/A	N/A	48 and/or 49	Five times per month
082X- Hemodialysis	Three times per week	71, 72, 73, 74, 76	A8, A9, D5	13 times in 30 days/ 14 times in 31 days
083X- Peritoneal dialysis	Three times per week	71, 72, 73, 74, 76	A8, A9, D5	13 times in 30 days/ 14 times in 31 days
084X- CAPD	Daily	73 or 74	A8, A9, D5	13 times in 30 days/ 14 times in 31 days
085X- CCPD	Daily	73 or 74	A8, A9, D5	13 times in 30 days/ 14 times in 31 days

HCPCS paid outside of the ESRD PPS with an effective date mid-month, or a fee schedule rate change mid-month

The Fiscal Intermediary Shared System (FISS) uses the “from date” instead of the line-item date of service on ESRD PPS claims to determine how to process HCPCS not paid under the ESRD PPS.

When billing a HCPCS not covered under ESRD PPS, the ESRD claim should be split based on the effective date of the change to the HCPCS.

If a HCPCS rate changes mid-month, the claim should be billed split to allow the correct rate to be applied or if the service is able to be submitted alone, i.e., COVID or flu codes, submit the service on a 72X claim by itself.

• Example split claim: HCPCS rate changed on 05/19.

• First claim should be billed from 05/01-05/18.

• Second claim should be billed from 05/19-05/31 with the HCPCS on the 05/19-05/31 claim.

• This will allow FISS to apply the correct rate based on the 05/19 “from date.”

• Example split claim: HCPCS effective date 05/03.

• First claim should be billed from 05/01-05/02.

• Second claim should be billed from 05/03-05/31 with the HCPCS on the 05/03-05/31 claim.

• This will prevent the service from receiving a reason code for invalid HCPCS based on the 05/03 “from date.”

• Example claim with HCPCS by itself: HCPCS rate changed 05/19.

• The HCPCS should not be reported on the ESRD PPS claim. Bill normal ESRD PPS claim with from 05/01-05/31.

• For the HCPCS with the rate change, submit the 72X claim with just the date of service the HCPCS was provided, for example from 05/25-05/25 with any appropriate additional coding that may be required for the specific HCPCS.

• This will allow FISS to apply the correct rate based on the “from date.”
