Key Takeaways
HCPCS Code J2704 is the Level II billing code for injection, propofol, 10 mg (brand name Diprivan), used for anesthesia and procedural sedation claims.
Each billing unit equals 10 mg of propofol administered. A 200 mg dose requires 20 units on the claim.
Medicare reimburses J2704 via ASP+6% methodology; the 11-digit NDC must accompany every Part B drug claim or the claim will reject.
Pabau’s claims management software helps outpatient facilities document propofol administration, calculate units, and submit accurate HCPCS J-code claims.
HCPCS Code J2704: Definition, code attributes, and billing overview
HCPCS Code J2704 is the Level II billing code for injection, propofol, 10 mg, the fast-acting IV sedative used for anesthesia, procedural sedation, and ICU sedation.
Propofol is one of the most widely administered IV anesthetics in outpatient surgery, and J2704 billing errors account for a disproportionate share of Part B drug claim rejections. The two most common mistakes are incorrect unit calculation and a missing NDC.
This guide covers the official code descriptor, unit math, Medicare ASP reimbursement, NDC crosswalk, modifiers, paired ICD-10 codes, common coding errors, and when to use J3490 instead. For outpatient facilities using claims management software, accurate J-code documentation starts with understanding what the descriptor requires at the claim level.

Propofol (Diprivan): clinical context for billing specialists
Understanding what propofol does clinically helps billers apply J2704 correctly and link the right diagnosis codes. Propofol is a short-acting IV sedative-hypnotic agent. Its rapid onset (30-60 seconds) and short duration make it the drug of choice for three distinct billing contexts, each of which affects claim construction differently.
- Anesthesia induction and maintenance: Administered in bolus and continuous infusion for general anesthesia in surgical settings, including outpatient plastic surgery practices. When propofol is part of a complete anesthesia service, bundling rules apply (see billing errors section).
- Procedural sedation: Used for colonoscopy, endoscopy, bronchoscopy, and minor surgical procedures. This is the most common outpatient facility context for J2704 claims.
- ICU sedation: Continuous infusion in intensive care settings. Billing in this setting typically involves facility-level claim construction under the OPPS rather than the Physician Fee Schedule.
Propofol comes as an injectable emulsion at 10 mg/mL concentration. A standard 20 mL vial contains 200 mg. Knowing the concentration matters because unit calculation errors almost always trace back to a misread vial label. For IV therapy practice workflows, drug concentration documentation at the point of care is the first line of billing accuracy.
The drug is also known by the brand name Diprivan (Fresenius Kabi), though generic manufacturers including Hospira/Pfizer produce propofol formulations that map to the same J2704 code. IV therapy practice management systems that track drug lot numbers and NDCs at administration time simplify the NDC reporting step at claim submission.
Pro Tip
Document the propofol vial concentration, total volume administered, and lot number in the clinical note at the time of service. This creates a direct audit trail from the administration record to the units billed on the J2704 claim.
J2704 billing unit calculation: The 10 mg rule
The single most common J2704 billing error is an incorrect unit count. The rule is simple: one billing unit equals 10 mg of propofol administered. Divide the total milligrams given by 10 to get the units to report on the claim.
Bill only for the quantity actually administered to the patient, not the full vial. If 150 mg was drawn and 120 mg administered, bill 12 units. Billing for the full vial when less was used constitutes overbilling and is an OIG audit red flag. IV therapy documentation software that captures administered dose separately from drawn dose prevents this discrepancy at the source.
Medicare reimbursement for HCPCS Code J2704
Medicare reimburses J2704 under the Part B drug benefit using the Average Sales Price (ASP) methodology, as governed by the Centers for Medicare and Medicaid Services (CMS). The payment rate is ASP+6% per billing unit, updated quarterly via the CMS ASP Drug Pricing Files. Because rates change every quarter, never hardcode a dollar figure into billing workflows. Always pull the current rate from the official CMS publication.
To find the current Medicare payment limit for J2704, access the CMS fee schedule lookup tool or download the quarterly ASP pricing file directly from CMS.gov. The file lists the payment limit per HCPCS code per unit.
J2704 fee schedule by payer
Medicare’s ASP+6% rate applies only to Medicare Part B claims. Other payers follow different methodologies.
Facility versus non-facility differentials also apply. Hospital outpatient departments billing J2704 under the OPPS receive a packaged payment in many cases, which may differ from the standalone ASP+6% amount. Confirm the payment status indicator in the OPPS Addendum B for the applicable calendar year.
NDC codes associated with J2704
For Medicare Part B drug billing, CMS requires the 11-digit NDC to appear on every J2704 claim. This is a compliance requirement, not a recommendation. Claims submitted without the NDC will reject at the payer level. The NDC must reflect the actual product administered, not a substitute or generic equivalent with a different NDC, even if both products map to J2704.
Propofol injectable emulsion at 10 mg/mL is manufactured by several companies. Common NDC prefixes associated with J2704 include products from Fresenius Kabi (Diprivan) and Hospira/Pfizer, as well as other generic producers. Cross-reference the exact 11-digit NDC against the current AAPC HCPCS code lookup or the FDA DailyMed database to confirm the active NDC for each product in your formulary before claim submission. Proper medical documentation forms that capture the administered drug’s NDC at point of care eliminate the common “biller had to guess the NDC” error.
NDC reporting format on claims
The 11-digit NDC must be submitted in a specific format. For professional claims (CMS-1500 or 837P), report the NDC in the NDC qualifier field using the 5-4-2 format (labeler-product-package). On institutional claims (UB-04 or 837I), the NDC appears in the appropriate revenue code line. The unit of measure qualifier must accompany the NDC. For a per-unit drug like propofol, that qualifier is typically “UN”. Missing either the NDC or the unit qualifier triggers an automatic claim rejection. Digital documentation forms that capture NDC and administered dose at the point of service feed directly into clean claim construction.

Applicable modifiers for J2704
Modifiers refine how the claim describes the drug administration method. Applying the wrong modifier, or omitting one that a payer requires, produces a denial. The following modifiers are most commonly used with J2704.
Some commercial payers and Medicare Advantage plans have modifier requirements that differ from traditional Medicare. Always verify modifier requirements in the payer’s current billing guidelines. Use the PGM HCPCS lookup tool to cross-reference modifier applicability for J2704 before submission.

ICD-10 diagnosis codes commonly paired with HCPCS Code J2704
Propofol claims require a linked ICD-10-CM diagnosis code that supports medical necessity. Coverage is diagnosis-dependent and payer-specific. Propofol is not covered for all uses under all payer policies. The table below shows ICD-10-CM codes commonly billed alongside J2704, based on the clinical indications for procedural sedation and anesthesia. Postprocedural pain diagnoses like G89.18 follow the same documentation logic as the sedation-linked codes above.
The ICD-10-CM code must reflect the primary reason for the patient encounter, not just the drug administered. Auditors look for diagnosis codes that clinically justify propofol use. A claim for J2704 paired with a diagnosis that does not require sedation or anesthesia will trigger a medical necessity review. The same logic applies to routine pairings like Z12.11, used for colonoscopy screening sedation, where the diagnosis code must clearly support why sedation was administered.
Coding guidelines and common billing errors for J2704
These are the five billing errors that generate the most J2704 denials and OIG audit flags.
1. Incorrect unit count
Billing the full vial instead of the administered dose is the most common error. Document milligrams administered in the clinical record and calculate units at claim time. Billing 20 units for a 100 mg dose (instead of 10) triggers an automatic edit flag for most payers.
2. Missing NDC
Every Medicare Part B J2704 claim requires the 11-digit NDC. Omitting it causes an automatic rejection. The NDC must match the actual product administered. A Fresenius Kabi NDC cannot substitute for a Hospira/Pfizer NDC, even though both map to J2704. Ensure your drug administration records capture the lot number and NDC at the time of administration.
3. Unbundling with anesthesia CPT codes
When propofol is the primary anesthetic agent billed via an anesthesia CPT code such as 01951, billing J2704 separately may constitute unbundling. The anesthesia CPT code generally includes the drugs used as part of the anesthesia service. Billing J2704 as a separate line item in that context produces a duplicate billing situation. Verify with each payer’s specific policy before billing J2704 alongside anesthesia CPT codes. This is an uncertain area, so documentation should clearly support the distinction between bundled anesthesia and separately billable drug administration.
4. Wrong modifier or omitted modifier
Applying QZ when a physician actually medically directed the case (which calls for QX instead) will cause a denial or trigger an audit. Using modifier 59 without clear documentation that the service was distinct from a related procedure also invites audit scrutiny. Review modifier requirements before each submission cycle.
5. Missing or weak medical necessity documentation
The clinical note must support why propofol was clinically necessary for this patient on this date. A note that documents only “propofol administered 200 mg IV” without linking to a diagnosis or clinical indication does not meet the medical necessity standard. Pair the claim with a diagnosis code that directly maps to the procedure requiring sedation, and ensure the note documents the clinical rationale. Practices that document anesthesia CPT codes like 01772 with the same rigor reduce this category of denial significantly.
Pro Tip
Run a quarterly audit of J2704 claims: pull all submissions, verify unit count against clinical administration records, and confirm NDC on each line. Most billing errors are systematic. One root cause generates dozens of incorrect claims. Fix the process, not just the individual claim.
How J2704 differs from J3490 and other miscellaneous drug codes
J3490 is the HCPCS Level II unclassified drug code, used when no specific J-code exists for the drug administered. Because propofol has a dedicated code (J2704), billing J3490 for propofol is technically incorrect and creates reimbursement risk. The table below clarifies when each code applies and why the specific code matters.
J3490 claims require a drug invoice and letter of medical necessity submitted with the claim. Medicare payers manually price these, which means delayed payment and higher denial probability. Using J3490 for propofol, a drug with a specific assigned code, also raises a compliance flag, since it bypasses the standard ASP pricing methodology. Anesthesia CPT codes like 01932 carry the same expectation: bill the specific code, not a miscellaneous placeholder.
Conclusion
J2704 billing errors cluster around three failures: wrong unit count, missing NDC, and incorrect unbundling assumptions. Each is preventable with the right documentation process at the point of care.

Frequently asked questions
What is HCPCS Code J2704 used for?
HCPCS Code J2704 is the billing code for injection, propofol, 10 mg, a short-acting IV sedative-hypnotic drug used for anesthesia induction and maintenance, procedural sedation (colonoscopy, endoscopy, minor surgery), and ICU sedation. Each billing unit represents 10 mg of propofol administered.
What is the billing unit for J2704 propofol?
One billing unit equals 10 mg of propofol. Divide the total milligrams administered by 10 to calculate the correct unit count. For a 200 mg dose, bill 20 units. Bill only the quantity actually administered, not the full vial drawn.
What is the Medicare reimbursement rate for J2704?
Medicare reimburses J2704 at ASP+6% per billing unit under the Part B drug benefit. Rates are updated quarterly by CMS in the ASP Drug Pricing Files. Always pull the current rate directly from CMS.gov before billing. Never use a hardcoded figure, since rates change every quarter.
What is the propofol J-code and do I need an NDC?
The propofol J-code is J2704. Yes, an 11-digit NDC is mandatory on every Medicare Part B claim for J2704. The NDC must reflect the exact product administered. Claims submitted without the NDC are automatically rejected by Medicare payers.
What is the difference between J2704 and J3490 for propofol billing?
J2704 is the specific HCPCS code for propofol and should always be used. J3490 is an unclassified drug code reserved for drugs without a specific J-code. Using J3490 for propofol is incorrect, requires manual payer review, delays payment, and increases denial risk compared to the specific J2704 code.
Does Medicare cover J2704 in outpatient settings?
Medicare Part B covers J2704 in outpatient settings when medical necessity is supported by an appropriate ICD-10-CM diagnosis code. Coverage is diagnosis-dependent. Propofol administered as part of a covered procedure (such as colonoscopy sedation) is generally reimbursable, but the claim must include a diagnosis code that clinically justifies the drug’s use.
