Venipuncture at a follow-up visit


What documentation is required when a medical assistant performs venipuncture on a date when the patient is not seen by the physician?


The documentation should refer to the written lab order by date and location (e.g., “in the 8/31/16 progress note”) and list the date of venipuncture, time, site, and patient tolerance of the procedure. All documentation should include the legible signature (written or electronic) and credentials of the individual performing the service.

Debridement of subcutaneous tissue


Which CPT code should be reported for debridement of subcutaneous tissue on two separate wounds?


Code 11042, “Debridement, subcutaneous tissue (includes epidermis and dermis, if performed); first 20 cm2 or less,” is reported once for the first 20 square centimeters or less of the combined wound surface measurements. When multiple wounds are debrided at the same level, use the sum of their surface areas in code selection. However, if multiple wounds are debrided at different levels, report separate codes for each wound (e.g., 11042 for debridement of subcutaneous tissue and 11043 for debridement of muscle and/or fascia). Code 11045 may be reported for each additional 20 square centimeters.

Body mass index


We have been advised that due to new ICD-10 guidelines, codes for body mass index (BMI) should be reported only when the BMI impacts the care of the patient. However, measuring and reporting the BMI is tied to a quality initiative. Can we report BMI codes when the measurement is necessary for this purpose?


Yes. The BMI code is a status code that may be reported to indicate that a patient's body mass was incorporated into the clinical evaluation of the patient's health status. It is always a secondary code to the primary reason for an encounter (e.g., well-visit, weight loss, obesity, etc.). The latest guidelines did add instructions
