2024 Medicare fee-for-service only, national totals — Medicare Advantage, Medicaid and commercial volume are excluded, so real-world use runs higher. This is a calendar-year snapshot from the CMS Physician & Other Practitioners dataset, on a different cycle from the Q4 2016 fee schedule the rates above come from.

Common questions Copy link

Why is there no payment amount for 82310?

Its status indicator is X (statutory exclusion). The statutory definition of physician services does not include this item. The blank is deliberate: the amount is either unknown or paid under another provision, so reading it as $0 would be wrong.

Why would a Medicare claim for 82310 be denied or paid less?

Each item below comes from a CMS indicator on this page — not general billing advice.

  • Its status indicator is X (statutory exclusion) — The statutory definition of physician services does not include this item. See status indicators

Payer-specific coverage and documentation rules live outside these files, so a claim that clears every check here can still be denied on other grounds.

When does this rate change?

CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. See what changed each release, or get an email when a new release moves rates.

For patients
What does CPT code 82310 mean?

CPT code 82310: Total Calcium Blood Test. A common example is the calcium value on a routine chemistry panel that comes back high, prompting your doctor to check your parathyroid hormone and ask whether you have had kidney stones or bone pain.

Computation & policy

How this amount is computed Copy link

amount = (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.

Release Q4 2016
Component RVU
Work RVU blank
Practice expense RVU (non-facility) blank
Practice expense RVU (facility) blank
Malpractice RVU blank

Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead — higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, and never as zero.

Source & method

Show sources

This is computed from CMS's Medicare Physician Fee Schedule Q4 2016 release (schedule pfs, effective October 2016). National amounts apply a GPCI of 1.000 and leave sequestration off. The status indicator decides payability, never the RVU values, so a blank RVU stays blank. Releases are immutable: a rate retrieved for a past quarter always reflects that release. Commercial and cash-pay figures anywhere on this page are arithmetic on the Medicare amount, using commonly cited reimbursement ranges. They're illustrative, and no nationwide claims database stands behind them. Our methodology covers all of this in depth — sourcing, parsing, versioning, and how claims are cross-checked before they ship.
