💊 About Mecasermin Injection DRUG GUIDE

Increlex (mecasermin) injection is used to treat growth failure in children aged 2 and older who have severe primary IGF-1 deficiency — a condition where the body cannot make enough IGF-1, a hormone essential for normal growth.

It is also used in children with a growth hormone gene deletion who have developed antibodies that block growth hormone from working.Increlex is not a replacement for growth hormone (GH) therapy and is not approved for other causes of short stature such as GH deficiency, malnutrition, thyroid problems, or long-term use of high-dose corticosteroids.

The CMS payment limit is the Medicare Part B drug allowance (ASP + 6%, statutory). After the 2% federal sequester the effective payment is ≈ ASP + 4.3%; estimated ASP = payment limit ÷ 1.06. Source: CMS Medicare Part B Payment Limit File (quarterly).

🧮 Dosing & billing-units calculator HCPCS UNITS

One billing unit of J2170 = 1 unit. Enter a regimen to convert dose → billing units and project a full course.
Billing units = dose ÷ HCPCS unit size. Most payers require whole units — round per the payer's policy. “Est. Medicare pay” uses the current payment limit. For single-dose vials, drug discarded after administration may be separately billable with modifier JW (JZ when none is discarded) where allowed. Always verify payer-specific rounding before billing.

🔁 NDCs that bill under J2170 CROSSWALKED NDCs

2 NDCs map to J2170. Bill units = how many HCPCS units one package represents.

NDC→HCPCS mappings come from the CMS ASP NDC-HCPCS crosswalk; additional DME MAC / DMEPOS mappings come from PDAC and are labeled separately. NADAC from CMS (weekly). “Status” reflects the product's marketing / obsolete flag in the NDC directory. Presence or absence here does not determine Medicare coverage.

🗺️ Medicare utilization & spend CMS · PART B

No reportable public Medicare utilization was found for J2170. This is expected for newer codes, low-volume drugs, or codes whose use is billed under another code. CMS also hides any figure covering fewer than 11 patients (a privacy rule), so small-volume use may exist but isn't publishable. Utilization and spend appear here automatically once CMS publishes reportable data for this code.

📊 What bills under J2170

J-codes are billing codes often used for drugs billed under the medical benefit. This connects the billing code to the NDC package records it covers, by ingredient and labeler.

⚠️ Practical billing caveats

  • A crosswalk is not coverage. An NDC mapping or a published payment limit does not guarantee a payer will cover or pay this code. Check the specific plan's policy.
  • Units ≠ milligrams. Bill the number of HCPCS units (dose ÷ the code's unit size), not the milligram dose. Use the calculator above.
  • Discarded drug. For single-dose vials, drug discarded after administration may be separately billable with modifier JW (and JZ when nothing is discarded) where the payer allows.
  • Rounding & partial units. Many payers require whole units; round per the payer's policy, not automatically up.
  • The code can cover more than this drug. Some HCPCS codes span multiple products or strengths — confirm the exact code for the product administered.
  • Figures lag. ASP limits change quarterly and utilization data are released with a delay. Verify against the current CMS files before billing.
