A method of decoding video data includes receiving encoded data for a current block of the video data, the current block comprising one or more escape mode encoded samples and decoding, from the encoded data, a value indicating that the current block includes the one or more escape mode encoded samples. The method further includes, in response to determining that the value indicates that the current block includes the one or more escape mode encoded samples and that a current tree type for the current block is not dual tree chroma, decoding an absolute value for a luma delta quantization parameter for the current block and a sign for the luma delta quantization parameter. The method further includes reconstructing the current block based on the absolute value for the luma delta quantization parameter for the current block and the sign for the luma delta quantization parameter.
