How To Use CPT Code 88299

CPT 88299 describes an unlisted cytogenetic study that is not represented by any specific code. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 88299?

CPT 88299 is used to report cytogenetic procedures that do not have a specific code available. It is used when the analyst performs a cytogenetic study that is not represented by any of the standard and active CPT codes. This code allows for the identification of inherited or acquired chromosomal abnormalities through the study of chromosomes using light or fluorescent microscopy.

2. Official Description

The official description of CPT code 88299 is: ‘Unlisted cytogenetic study.’

3. Procedure

1. The analyst performs a cytogenetic study using light or fluorescent microscopy.
2. The study involves the examination of chromosomes to identify any inherited or acquired chromosomal abnormalities.
3. Specific techniques and methodologies may vary depending on the nature of the study and the specific abnormalities being investigated.
4. The results of the study are documented and reported.

4. Qualifying circumstances

CPT 88299 can be used when there is no specific code available to accurately describe the cytogenetic study being performed. It is important to note that this code should only be used when there is no other appropriate code that closely represents the service provided. The decision to use CPT 88299 should be supported by the lack of a specific code and the need for an unlisted procedure code to accurately report the service.

5. When to use CPT code 88299

CPT code 88299 should be used when there is no specific code available to accurately describe the cytogenetic study being performed. It is important to follow the CPT guidelines and not choose a code that merely approximates the service provided. If there is a Category III code available that represents the service, it should be used instead of an unlisted procedure code. However, if no specific procedure or service code exists, CPT 88299 can be used to report the service.

6. Documentation requirements

To support a claim for CPT 88299, it is important to provide thorough documentation. This should include a cover letter explaining the reason for choosing the unlisted code instead of a defined, active code. The documentation should also include one or more similar codes and a comparison of the service to those codes to justify the claim amount being billed. Additionally, operative notes or other relevant documentation should be included to strengthen the claim and avoid a possible denial. Payers will consider claims with unlisted procedure codes on a case-by-case basis and determine payment based on the documentation provided.

7. Billing guidelines

When billing for CPT 88299, it is important to follow the billing guidelines. Ensure that there is no specific code available to accurately describe the cytogenetic study being performed. Include a cover letter explaining the reason for using the unlisted code and provide supporting documentation. It is also important to compare the service to similar codes and justify the claim amount being billed. Remember to submit the claim with the appropriate modifiers and any additional required information.

8. Historical information

CPT 88299 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.

9. Examples

1. An analyst performs a cytogenetic study on a patient’s blood sample to identify any chromosomal abnormalities that may be contributing to their developmental delays.
2. A laboratory technician examines a bone marrow sample using fluorescent microscopy to detect any acquired chromosomal abnormalities in a patient with suspected leukemia.
3. A cytogeneticist analyzes a tissue sample from a tumor to determine if there are any specific chromosomal abnormalities that may be driving its growth.
4. A genetic counselor performs a cytogenetic study on an amniotic fluid sample to screen for any chromosomal abnormalities in a pregnant patient.
5. A researcher conducts a cytogenetic study on a cell culture to investigate the effects of a specific chemical exposure on chromosomal integrity.
