What 87110 covers

A clinical microbiology laboratory cultures submitted material to detect chlamydial organisms. Genital specimens, such as cervical or urethral samples, are common; conjunctival specimens may also be submitted when ocular infection is suspected. The ordering clinician selects the specimen site based on the suspected infection, and the laboratory performs the culture and reports the result.

Report this code for chlamydia culture itself, rather than nucleic acid probe or antigen detection. The code applies to culture from any source; select it based on the method performed, not solely on the specimen site. Medicare pays it through the CLFS at one national amount across localities, without geographic adjustment or an office-versus-facility payment difference. The 2026 national CLFS amount is $19.60, unchanged since 2020. Medicare pays the test through the CLFS.

How Medicare pays 87110

Clinical lab tests aren’t priced like physician services. They’re paid from their own fee schedule, with its own rules. See the whole lab fee schedule.

One national amount

CMS sets a single Clinical Laboratory Fee Schedule amount for 87110. There’s no geographic (GPCI) adjustment, so it pays the same in every state and payment locality.

No office or facility rate

Lab tests aren’t built from relative value units, so there’s no office and facility split: the place of service doesn’t change the CLFS amount.

Updated every quarter

CMS republishes the CLFS each quarter. New tests, often proprietary laboratory analyses (PLA codes), join during the year; existing amounts are updated each January.

Excluded from the physician fee schedule

The physician fee schedule lists 87110 with status X (excluded by statute), so the test itself is paid only from the CLFS.

87110 billing questions

When should this code be used instead of a chlamydia probe code?

Use 87110 when the laboratory performs culture. A direct or amplified nucleic acid probe is reported with the code matching that method, not as a culture.

Does this code describe a specific specimen site?

No. It applies to chlamydia culture from any source, with the specimen site selected according to the suspected infection.

Does this code include specimen collection?

It represents the culture test, not a specimen-collection service.

Which Medicare payment schedule applies?

Medicare pays 87110 through the CLFS, with one national amount across localities and no office-versus-facility payment difference.
